CSV coordinates to map
Plot a CSV (or TSV / Excel) with latitude and longitude columns as points on a map. Free for Mac and Windows. Drag the file in; overlay a Shapefile or GeoTIFF. Files stay on your computer — not “CSV to Google Maps.”
How · .csv / .tsv / .xlsx
Drag it open on Mac or Windows
Drag the spreadsheet into NimbleMap. It picks latitude and longitude columns (or you choose them). Points land on the map; colour by a field; stack with other layers.
Why not a browser tab or QGIS
Free, local, and enough for a look
Online “CSV to map” tools are crowded and upload your rows. Google My Maps owns “CSV to Google Maps” — we do not chase that. NimbleMap is for desktop CSV coordinates to map: large local files, offline, and overlay with a Shapefile that browsers handle poorly.
