    Batch coordinate files: a quick guide

    Every instrument and CAD package exports a different column order: total stations, GNSS rovers, and AutoCAD Civil 3D produce PENZD (point, easting, northing, elevation, description) or PNEZD files, while raw point clouds come as XYZ. This tool reads CSV, Excel (.xlsx), KML, GeoJSON, and DXF, and lets you map each column to its role or apply a one-tap preset — so thousands of points convert at once between any of the 195 systems (Egypt belts, Ain el Abd, Nahrwan, Karbala, Deir ez Zor…), WGS84, and UTM.

    Invalid rows (a missing coordinate or non-numeric text) are isolated and counted without stopping the rest of the file, and the result exports in the format you pick — CSV for spreadsheets, DXF for AutoCAD, or KML/GeoJSON for maps (always emitted in WGS 84 per the standard). Because all conversion runs inside your browser, your file is never uploaded to any server — ideal for sensitive data.
