You can convert US or Canadian latitude/longitude coordinates (geocodes) to approximate addresses with Geocodio.
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.
