Latitude and Longitude are all that is needed to create a basic display on Google Earth.  Add a Name, Description, and an Icon for a professional presentation.

Advanced features support GPS tracks, Time Sliders, and Grid Coordinates.

To get started, read the Quick Start instructions or download the sample data ExcelToKmlDemo.zip.

NEW: AppendDataColumnsToDescription accepts a list of column names.

If you need help getting started, or if you have ideas for improvement, please write or call.

Quick Start

• Open Excel.
• Enter these words into separate cells on the first row: "Latitude", "Longitude", "Name", "Description", and "Icon".
• On the rows that follow, enter the attributes of each point.
• "Latitude" and "Longitude" are required.  The other columns are optional.
• "Name" is the label that appears next to each icon on Google Earth.
• "Description" is the text that appears in the Google Earth pop-up balloon.  An Excel formula can be used to combine data from several columns.
• "Icon" designates the icon that is displayed for each point.  An easy way to get an icon is to enter a number from the table below.  If the Icon column is left blank or if it is missing, icon number 166 is displayed.  You can also enter an icon's "www" web address.  If you don't want an icon, enter the word "none".
• Save the worksheet.
• Click the "Browse" button above and select the worksheet you just created.
• Click the "View on Google Earth" button.

To Save The File

• In the "Places" window of Google Earth, right-click the folder "Earth Point Excel To KML".
• From the pop-up menu, select "Save As".

Features

• Displays an xls, xlsx, xlsm, xlsb (Excel), csv (comma separated values) or txt (tab delimited) file on Google Earth.
• Excel columns "Latitude", "Longitude", "Name", "Description", and "Icon" are all that are needed for a professional looking presentation.
• Advanced options allow you to elevate the icon above the earth's surface, draw a path ("connect the dots"), and control mouse-over effects.
• Icons can be specified by entering a number from the table below or by entering the URL of an icon stored on a web server.
• Formulas may be entered into any cell of a spreadsheet. Formulas can be used to specify icons, icon scale, format the Description text, etc. Formulas cannot be used in csv or txt files.
• Column specifications are listed below.

GPS Track: use the following columns: Latitude, Longitude, LineStringColor, Icon, IconColor, and IconHeading.  Enter "lime" or "yellow" into the LineStringColor column. For direction arrows, enter "196" into Icon, "yellow" into IconColor, and "line-180" into IconHeading.  If you don't want an icon, enter "none" into the Icon column.  more...

Grid Coordinates: ExcelToKml supports:
Universal Transverse Mercator (UTM)
Universal Polar Stereographic (UPS)
Military Grid Reference System (MGRS)
MGRS Polar
U.S. National Grid (USNG) identical to MGRS
Global Area Reference System (GARS)
Maidenhead used by amateur radio operators
World Geographic Reference System (Georef)
State Plane United States only

LatLon can be joined as one coordinate.  See the specifications below.

Guidelines

• File name must end in ".xls", ".xlsx", ".xlsm", ".xlsb", ".csv", or ".txt"
• The first row that contains the values "Latitude" and Longitude" or the value "Position" is considered to be the heading row. All previous rows are ignored. All subsequent rows are treated as data.
• The columns listed below control the appearance of each placemark. "Latitude" and "Longitude" are required. All others are optional. Any column not listed is ignored.
• Multiple worksheets are allowed in an Excel workbook. Each worksheet name will be displayed as a separate folder in Google Earth "My Places".

Security

Excel To KML security is comparable to sending an email to a trusted colleague.  Your data is transmitted over the internet and saved as a file on the Earth Point server.  The data is immediately sent back to your PC in the form of a KML file and the original file is removed from the Earth Point server.

Columns Used By Excel To KML

Latitude, Longitude, Name, Description, and Icon are all that are necessary for a professional looking presentation.  Advanced options allow you to elevate the icon above the earth's surface, draw a path ("connect the dots"), and control mouse-over effects.  Excel To KML ignores any additional columns in your spreadsheet.

Required Columns
Column Heading	Default Value	Description
Latitude	None	Latitude of point.  Google Earth uses the WGS84 geodetic datum.  Valid formats include:   N43°38'19.39"   43°38'19.39"N   43 38 19.39   43.63871944444445 If expressed in decimal form, northern latitudes are positive, southern latitudes are negative. If blank or invalid, item is not displayed on Google Earth.
Longitude	None	Longitude of point.  Google Earth uses the WGS84 geodetic datum.  Valid formats include:   W116°14'28.86"   116°14'28.86"W   -116 14 28.86   -116.2413513485235 If expressed in decimal form, eastern longitudes are positive, western longitudes are negative. If blank or invalid, item is not displayed on Google Earth.
Basic Optional Columns
Column Heading	Default Value	Description
Name	None	The text displayed next to the icon on Google Earth. If blank, no text is displayed.
Description	None	The text displayed in the Google Earth pop-up balloon. An Excel formula can be used to combine text from several columns. For example, to display data from columns D, E, and F, with each of D, E, and F on its own line, and supposing we are on row 6, the Description column formula is =D6 & "<br/>" & E6 & "<br/>" & F6 where <br/> is the html tag for a new line. HTML tags are allowed. Note: An easy way to show all of the spreadsheet data columns is to use the AppendLatLonToDescription column heading, and to not use the "Description" heading at all. If blank, no balloon is displayed.
Icon		Icon can be any of: 1) A integer between 1 to 279, or 301 to 529, which designates an icon selected from either of the tables below; or 2) The URL of an icon stored on a web site; or 3) The path of a file on your hard drive or network drive, for example   C:/folder/file.jpg or   file:///C:folder/file.jpg   (note the three slashes, not two, after "file:"); or 4) the word "none". If the file cannot be found, Google displays . If "none", no icon is displayed. If blank, is displayed.
Advanced Optional Columns
Column Heading	Default Value	Description
AppendDataColumnsToDescription	None	Valid values are "True", "Yes", "x", "False", "No", blank, or a list of column names. If "True", "Yes", or "x": appends spreadsheet data to the Description text. Includes all columns NOT used to format the Excel To Kml output. Also includes the "Name", "Latitude", "Longitude", "Position", and "TownshipAndRange" columns. "Name" is used as the Description title. If "False", "No", or blank: does nothing. If a list of column names, such as "Address, Price, City, Color, Region": these columns (if they exist in the spreadsheet) are appended to the Description in the order listed. If "Name" is included in the list, then the "Name" value forms the Description title.
AppendLatLonToDescription	None	Valid values are "True", "Yes", "x", "False", "No", and blank. If true, appends Latitude and Longitude information to the Description text. Useful for seeing the translation of coordinates that are entered into the Position column. The description text is displayed in the Google Earth pop-up balloon. The description text is also displayed in the spreadsheet view on this web page. The following example reports that "30UXC3542" is entered into the Position column, that it is an MGRS coordinate for a 1-kilometer grid, and that the equivalent Lat/Lon is 51.812518, -1.0416 MGRS KM:  30UXC3542 Lat, Lon:  51.812518, -1.0416 If blank, no text is appended to the Description text. If the spreadsheet does not have a "Description" column, the text will nonetheless be displayed in the Google Earth pop-up balloon. However, no text will be added to the spreadsheet view on this web page.
Folder	blank	Organizes the data into folders and subfolders. When viewing the data in Google Earth, the entire contents of a folder can be hidden or shown by clicking the folder in the "My Places" window. Both forward-slashes and back-slashes can be used to separate the folder levels. Examples: Country One Country One/City One/Street One Country One/City Two Country Three/Office Four/Room Six
HideNameUntilMouseOver	False	Valid values are "True", "Yes", "x", "False", "No", and blank. If true, the icon is displayed with no label, until mouse over, then the label is displayed. If False, the label is always displayed. If there many rows in your data, is helpful to hide the labels to reduce screen clutter. If blank, Name is always displayed, regardless of mouse-over.
IconScale	1	A decimal number that increases or decreases the display size of the icon. Typical values are in the range of .5 to 1. No matter how big or small an image actually is, Google Earth displays it according to the scale. For example, Scale=1 Scale=.7 Scale=1.5 If blank, scale is 1.
IconAltitude	0	Height of icon above the ground (default) or sea level (optional), in meters. If blank, height is 0. See IconAltitudeMode, just below.
IconAltitudeMode	Relative	If blank, "Relative", "AGL", or "AboveGroundLevel", the altitude of the icon is measured from ground level. If "Absolute", "MSL", or "MeanSeaLevel", the altitude of the icon measured from sea level.
IconLineColor IconLineColour	Yellow	If the icon is elevated above the ground (see IconAltitude) this is the color of the line drawn from ground up to the icon. See IconColor for details. If "none", the line is not displayed. If blank, color is yellow.
IconColor IconColour	None	Fills an icon with a color. Can be any of 1) an HTML named color, 2) an HTML hexadecimal color code, 3) a Hue value, 4) the word "none". Bright colors show up best on Google Earth. Bright named colors:       Red DarkOrange Yellow Chartreuse       Lime SpringGreen Cyan DodgerBlue       Blue DarkViolet Magenta DeepPink             Black Gray Silver White Same bright colors as hexadecimal values:       FF0000 FF8000 FFFF00 80FF00       00FF00 00FF80 00FFFF 0080FF       0000FF 8000FF FF00FF FF0080             000000 808080 C0C0C0 FFFFFF Same bright colors as Hue values:       0 30 60 90       120 150 180 210       240 270 300 330             No black or gray colors if Hue is specified. All Hue values from 0 to 360: If blank or "none", the icon displays its default colors (see icon table below at the bottom of the page).
IconHeading	None	Rotates an icon. Can be a number, the word "line" or the word "line" plus or minus a number. A positive number rotates the icon to the right by the number of degrees specified by the number. A negative number rotates the icon to the left. The word "line" rotates the icon to face in the direction of travel. The word "line" plus or minus a number rotates the icon to face the direction of travel, then rotates it some more as specified by the number. If blank, or 0, the icon is not rotated.
LabelColor LabelColour	White	Color of the label that is displayed next to the ion on Google Earth. See IconColor for details. If "none", the label is not displayed. If blank, the label is white.
LabelScale	1	Size of the label that is displayed next to the ion on Google Earth. Typical values are in the range of .8 to 2. If blank, the scale is 1.
LineStringColor LineStringColour	None	"Connect the dots" - draws a line from this point to the next. See IconColor above for specification details. If "none" or blank, the line is not displayed. Except that if LineStringColor is blank and any of LineStringWidth, LineStringAltitude, or LineStringAltitudeMode are specified, then the color will be yellow.
LineStringWidth	2	Width of the line drawn from one point to the next. A decimal number, typically in the range of 1 to 3. If 0, the line is not displayed. If blank, width is 2.
LineStringAltitude	0	The altitude, in meters above the ground, of this end of the LineString. If blank, altitude is 0.
LineStringAltitudeMode	Relative	If blank, "Relative", "AGL", or "AboveGroundLevel", the altitude of the line is measured from ground level. If "Absolute", "MSL", or "MeanSeaLevel", the altitude of the line measured from sea level.
LineStringDescription	None	The text displayed in the line's Google Earth pop-up balloon. An Excel formula can be used to combine text from several columns. For example, to display data from columns D, E, and F, with each of D, E, and F on its own line, and supposing we are on row 6, the LineStringDescription column formula is =D6 & "<br/>" & E6 & "<br/>" & F6 where <br/> is the html tag for a new line. HTML tags are allowed. If blank, no balloon is displayed when the line is clicked.
AppendDataColumnsToLineStringDescription	None	Valid values are "True", "Yes", "x", "False", "No", blank, or a list of column names. If "True", "Yes", or "x": appends spreadsheet data to the LineStringDescription text. Includes all columns NOT used to format the Excel To Kml output. Also includes the "Name", "Latitude", "Longitude", "Position", and "TownshipAndRange" columns. "Name" is used as the Description title. If "False", "No", or blank: does nothing. If a list of column names, such as "Address, Price, City, Color, Region": these columns (if they exist in the spreadsheet) are appended to the Description in the order listed. If "Name" is included in the list, then the "Name" value forms the Description title.
AppendLatLonToLineStringDescription	None	Valid values are "True", "Yes", "x", "False", "No", and blank. If true, appends Latitude and Longitude information to the LineStringDescription text. Useful for seeing the translation of coordinates that are entered into the Position column. The description text is displayed in the Google Earth pop-up balloon. The description text is also displayed in the spreadsheet view on this web page. The following example reports that "30UXC3542" is entered into the Position column, that it is an MGRS coordinate for a 1-kilometer grid, and that the equivalent Lat/Lon is 51.812518, -1.0416 MGRS KM:  30UXC3542 Lat, Lon:  51.812518, -1.0416 If blank, no text is appended to the Description text. If the spreadsheet does not have a "Description" column, the text will nonetheless be displayed in the Google Earth pop-up balloon. However, no text will be added to the spreadsheet view on this web page.
LookAtHeading	0	If an icon is double-clicked in Google Earth, or its label in the Places window, Google Earth will spin so that the viewer is looking in this direction.
LookAtRange	1000 meters from the icon	If an icon is double-clicked in Google Earth, or its label in the Places window, Google Earth will move so that the viewer this far from the icon (slant range distance, in meters).
LookAtTilt	0	If an icon is double-clicked in Google Earth, or its label in the Places window, Google Earth will tilt so that the viewer is looking at the icon at this angle. If 0, then looking straight down. If 90, then looking straight across.
Position	None	The position of the icon, in a number of formats: LatLon, UTM, UPS, MGRS, MGRS Polar, USNG (identical to MGRS), GARS, Maidenhead, Georef, and State Plane. Used in place of Latitude and Longitude. The following positions refer to 39° 18' 40.58" N 102° 17' 30.47" W which is near Burlington, Colorado, USA. In the following table, "d" is used to mark degree digits, "m" for minutes, and "s" for seconds. For lat/lon, the letters "N, S, E, and W can come before or after the coordinates. So long as the coordinate can be understood, punctuation, spaces, and °'" are optional. Acceptable formats include: Dec Degs 39.3112710°,-102.2917960° dd.dddddd   ddd.dddddd Dec Degs Micro 39.3112710N,102.2917960W dd.dddddd ddd.dddddd Dec Mins 39°18.67626', -102°17.50776' ddmm.mmmm dddmm.mmmm Dec Mins 3918.67626N10217.50776W ddmm.mmmm dddmm.mmmm Deg Min Secs 39°18'40.5756", -102°17'30.4656" dd mm ss.sss    dd mm ss.sss   Dec Mins Secs 391840.5756N, 1021730.4656W ddmmss.sss dddmmss.sss UTM 13S 733494mE 4354817mN MGRS, USNG 13SGD3349454817 State Plane United States State Plane coordinates.

For each row of the spreadsheet: Exactly one of Latitude and Longitude, Position, TownshipAndRange, or TexasAbstract must be filled in. The others must be blank. If all are blank, or if more than one is filled in, then the row is in error and will not be mapped.
TownshipAndRange	None	Western United States only, in a number of formats. Used in place of Latitude and Longitude or Position. The Quarter/Quarter closest to our example position 39° 18' 40.58" N 102° 17' 30.47" W is the SE 1/4 of the NW 1/4 of Section 35, Range 44 West, Township 8 South, Sixth Meridian, Colorado.

In the above examples, both SENW 35 44W 8S 6th and SENW 35 44W 8S CO are both allowed. However, some states have more that one meridian, for example California has three. CA 14N 6E could be in any of the Humboldt, Mount Diablo, or San Bernardino meridians. Yet, Humboldt 14N 6E is allowed, as there is no chance of duplication. Likewise, a single meridian can cross into more than one state, causing duplication along the border. For example, 6th 12N 84W could be in either Colorado or Montana. However, Colorado 12N 84 West and Montana 12N 84W are permitted as there is no possibility of duplication. Other formats USGS Meridian Code may be used in place of the meridian name For example, California Humboldt 14N 6E would be CA 15 14N 6E BLM "Landkey" CO 6th 8S 44W 35 SENW would be CO06T0080S0440W035SENW BLM Geocoder format CA,21,016,0,N,002,0,W,029,NENE,0 CO,6,8,0,S44,0,W,35,SENW,0 USGS Code Meridian Name 1 First 2 Second 3 Third 4 Fourth 5 Fifth 6 Sixth 7 Black Hills 8 Boise 9 Chickasaw 10 Choctaw 11 Cimarron 12 Copper River 13 Fairbanks 14 Gila-Salt River 15 Humboldt 16 Huntsville 17 Indian 18 Louisiana 19 Michigan 20 Montana 21 Mount Diablo 22 Navajo 23 New Mexico 24 St. Helena 25 St. Stephens 26 Salt Lake 27 San Bernardino 28 Seward 29 Tallahassee 30 Uintah 31 Ute 32 Washington 33 Willamette 34 Wind River 35 Ohio River Base 36 Between the Miamis 37 Muskingham River 38 38 Unknown 39 Scioto River Base (First) 40 Scioto River Base 41 Scioto River Base (Third) 42 42 Unknown 43 Twelve-Mile-Square 44 Kateel River 45 Umiat 47 West of the Great Miami 48 U.S. Military Survey 91 Connecticut Western 92 Ohio Company Purchase The equivalent Lat/Lon coordinates can be displayed by: Add an AppendLatLonToDescription column to the spreadsheet.

Mouse-over the Position column entries. The Lat/Lon coordinates are displayed. For each row of the spreadsheet: Exactly one of Latitude and Longitude, Position, TownshipAndRange, or TexasAbstract must be filled in. The others must be blank. If all are blank, or if more than one is filled in, then the row is in error and will not be mapped.
Texas Abstract	None	State of Texas, United States only, in a number of formats. Used in place of Latitude and Longitude or Position. Example, abstract 1025 in Anderson county: The FIPS code for Anderson county is 001, so the complete abstract number is 0011025. The county name can be used in place of the FIPS code, as in Anderson 1025. The space between the county name or code and abstract number is optional. The following values will be interpreted as abstract 1025 in Anderson county. ="0011025" ="001 1025" '001 1025 '0011025 Anderson1025 Anderson 1025 Note that Excel removes leading zeros from numeric values. If 0011025 is entered into a cell, the value stored is 11025. Unfortunately, 11025 is not the number of any Texas Abstract. There are several ways to preserve the leading zeros. 1) Enter the value as a formula, ="0011025" 2) Precede the numeric value with a single quote, '0011025 3) Use the Excel toolbar to format the cell as "text". Show List of County FIPS Codes... The equivalent Lat/Lon coordinates can be displayed by: Add an AppendLatLonToDescription column to the spreadsheet. If the spreadsheet also has a "Description" column, then the Lat/Lon coordinates will be added to the description. Click the "View File on Web Page, Check for errors" button above. Mouse-over the Position column entries. The Lat/Lon coordinates are displayed. For each row of the spreadsheet: Exactly one of Latitude and Longitude, Position, TownshipAndRange, or TexasAbstract must be filled in. The others must be blank. If all are blank, or if more than one is filled in, then the row is in error and will not be mapped.
Snippet	None	A short text description that is displayed under the Name in the "My Places" section of Google Earth. If blank, no text is displayed.
TimeWhen	None	TimeWhen identifies a location that is to be displayed at a single moment in time. If blank or invalid the value is ignored. If you have GPS tracks or other data that contains time information, you can view this information sequentially using the time slider in Google Earth.  Google Earth Blog has more information about the time slider. Valid formats include: August 17, 2007 1:09:26 PM 8/17/07 13:09:26 2007-08-17 13:09:26 1:09:26 PM 2007-08-17 Eras are supported. AD (Anno Domini), BC (Before Christ), CE (Common Era), and BCE (Before Common Era), +, and - can appear before or after the date, or the era can be entered separately into the TimeWhenEra column. Generally speaking, the TimeWhenEra column is the easiest way to add an era. The reason is that if era is entered together with the date in the TimeWhen column, the date formatting will likely be lost, causing the Excel To Kml utility to report an invalid value. However, if the era is to appear together with the date in the TimeWhen column, as might be the case if the data is imported into Excel from another source, then the following are a few valid examples: 8/17/07 13:09:26 BC B.C.E. 8/17/07 13:09:26 AD 8/17/07 13:09:26 It is also possible to use a formula in the TimeWhen column to combine date and era.   ... C D E 1 ... Date Era TimeWhen 2 ... 2007-08-17 BC =Text(C2, "yyyy-mm-dd") & D2 3 ... Aug 17, 2007 B.C.E. =Text(E3, "yyyy-mm-dd") & D3 4 ... 8/17/07 - =Text(E4, "yyyy-mm-dd") & D4 The result in column E would be 2007-08-17 BC 2007-08-17 B.C.E. 2007-08-17 - (minus sign)
TimeWhenEra	blank	Eras are supported. AD or A.D. (Anno Domini), BC or B.C. (Before Christ), CE or C.E. (Common Era), BCE or B.C.E. (Before Common Era), + (plus), - (minus) If blank or invalid the value is Common Era, also known as AD.
TimeBegin	None	Indicates that the location is displayed for a span of time starting at TimeBegin. TimeBegin is often paired with TimeEnd. However, if TimeBegin is specified, but TimeEnd is missing, the location is displayed from TimeBegin forever after. Eras are supported. See TimeWhen for details. If blank or invalid the value is ignored.
