    Frequently asked questions

    What columns do I need?▾

    Any two columns named latitude/longitude (also lat, lng, lon, long, y, x). All other columns are kept as point properties.

    Why is my CSV limited to 100 rows?▾

    The free tool is capped to keep things instant. Signed-in Free accounts handle thousands of rows; paid tiers handle 100k+.

    Is my data uploaded?▾

    No — parsing happens entirely in your browser.

    My coordinates look wrong on the map.▾

    GeoDataMapper expects WGS84 (longitude ±180, latitude ±90). If your CSV uses a projected system like UTM, convert first with our coordinate converter.
