    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.
