Importing Data from .csv

The Map Maker .csv file import option allows you to rapidly import a large number of locations.

CSV File Format Notes:

Map Maker expects, at a minimum, the following fields/columns. These must be defined in the header row of your .csv file:

For best results, please use a comma-delimited file which does not encapsulate fields with quotes, as some data processors (such as Excel) export data where only some fields use quotes. This can confuse the parser.

Please see this example.csv file (you can view this file with a text editor or spreadsheet application, such as Excel).

Note About Lat/Lng Formats: Map Maker attempts to convert from various latitude/longitude formats, such as DMS (Degrees-Minutes-Seconds), into DD (Decimal Degrees), which offers the best results with the Google Maps API. If possible, we recommend uploading lat/lng data in decimal format.

A file upload dialog window will open.

Step 4: Browse for the .csv file you wish to upload and select to begin the file upload.

Once the file is uploaded and processed, the location data will be added to a new layer and loaded onto the current map.
