Troubleshoot data imports

Some data sets and browsers might cause problems when importing information into My Maps.

Grant your browser permission

If you're having trouble importing data into My Maps, you might need to give Google My Maps permission to access your Google Drive files. For Chrome users, here's how:

  1. Open Google Chrome on your computer and make sure you're signed in
  2. In the top right corner of the toolbar, click the Chrome menu Menu.
  3. Click Settings.
  4. Scroll to the bottom of the page and click Show advanced settings.
  5. Under “Privacy,” click Content Settings.
  6. Scroll down to “Pop-ups” and click Manage exceptions.
  7. Make sure that is listed as "allow." If it’s not, type "" into the "Add a new hostname" box.

Format data sets correctly

If you're having trouble importing data into My Maps, you might need to make sure that your spreadsheet:

  • Is a CSV, TSV, KML, KMZ, XLSX, or Google Sheets file. 
  • At least one column contains one of these types of geographic information:
    • Latitude-longitude information
    • Addresses
    • Place names
  • Has no more than 2000 rows. If your file has more than the maximum number of rows, split up your data into multiple files, and then import them into separate layers. Rows beyond the 2000 limit won’t be imported and won’t show up in the map or data view.
  • Is formatted with a first row that contains the column title(s).

Note: You can only import one data file per layer.

Adjust KML files

You can import KML files with data that My Maps support. You can import:
  • Feature types: points, lines, shapes.
  • Icons: stock or custom (including from URLs).
  • Images and videos from links in the info windows. My Maps does not store images or videos.
KML file information that won't load

Some of the following items in your file might not load:

  • Info balloons with HTML or JavaScript
  • KML tours
  • Time-based elements
  • Image and screen overlays
  • MultiGeometries
  • 3D models
  • Folders
