Batch coordinate file converter
Upload a survey file (CSV / Excel / KML / GeoJSON / DXF), map its columns, and convert all its points across 195 Arab-world systems — download in any format, all in your browser.

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.

FAQ
- Which import/export formats are supported?
- Import: CSV/text, Excel (.xlsx), KML, GeoJSON, and ASCII DXF. Export: CSV, Excel, GeoJSON, KML, and DXF. KML and GeoJSON always export in WGS 84 (lon/lat) per the standard.
- How do I map my CSV columns?
- After upload we show the first rows with a role dropdown per column (name, easting, northing, height, longitude/latitude…) plus one-tap presets (PENZD, PNEZD, XYZ). Invalid rows are isolated and counted without stopping the rest of the file.
- Is my file uploaded to a server?
- No. All conversion runs inside your browser; the file never leaves your device. We only record an anonymous usage tally (point count, systems, approximate work area) with your consent — same as the other tools.
- How accurate is the conversion?
- It uses the published EPSG datum shifts — centimetres to a few metres depending on the system. For certified centimetre-grade work, ask about our geodetic adjustment service.
- How many points can I convert at once?
- The converter handles tens of thousands of points in the browser, converting in chunks to keep the UI responsive. The practical limit depends on your device’s memory — typical files (thousands of points) convert in seconds.
- Does it keep heights (Z) and point names?
- Yes. If you map the height (Z/elevation) column and the name/ID column, both travel with each point into the output; the Z value migrates between “height” and “elevation” when the system kind (geographic/projected) changes.
