Felt reads many tabular spreadsheet formats, including:


Tabular data such as spreadsheets can reference geography in many forms: explicitly with lat/lon points and geometries, or implicitly with zip codes, place names, or street addresses.

See the Geocoding Addresses and Geomatching Regions pages for more about data without lat/lons.

Choosing Columns

Felt uses AI to identify the geometry columns in your data but we don’t always get it right first time. Fortunately, you can always pick the right ones - even if the upload failed!

Simply open the data table, select the appropriate columns and map them to the right field types. Remember: selecting address columns will result in Geocoding Addresses, while country names or ZIP codes will result in Geomatching Regions.



See the Troubleshooting Data Problems page for common upload failures and how to fix them.
