You can convert US or Canadian latitude/longitude coordinates (geocodes) to approximate addresses with Geocodio.
You can also add any of our data appends, such as Census tracts or Congressional districts, when reverse geocoding. See our full list of data appends here.
You can format your spreadsheet as single column (with latitude/longitude in one column) or with latitude/longitude in separate columns. You can download an example spreadsheet of coordinates for geocoding here.
When you upload a spreadsheet of latitude/longitude coordinates or use our API, we will return the closest street address, city, county, state, and country. You can download an example result here.
