Surveying file format converter
KML to DXF, Shapefile to GeoJSON, CSV to KMZ… eight formats with full geometry (points, lines, polygons), preserved attributes and reprojection across 195 Arab-world systems — all in your browser; the file never leaves your device.

FAQ
- Is my file uploaded to a server?
- No. Reading, converting and downloading all happen inside your browser; the file never leaves your device. We only record an anonymous usage tally (feature count, formats, approximate work area) with your consent — same as the other tools.
- Which formats are supported?
- Eight formats in AND out: CSV/text, Excel (XLSX), GeoJSON, KML, KMZ, GPX, DXF (ASCII AutoCAD) and zipped Shapefile (shp/shx/dbf/prj). Points, lines and polygons (with holes) plus the Multi* variants are all supported.
- What must a zipped shapefile contain?
- Upload a ZIP holding at least the .shp (geometry), .dbf (attribute table) and .prj (coordinate system) — plus .cpg for encoding when present. Exports produce a complete ZIP with those files and a README documenting any field renames (the 10-character dBase limit).
- Why do KML, GPX and GeoJSON always export in WGS 84?
- Their specifications mandate WGS 84 longitude/latitude (the GPS system). The tool reprojects automatically from your source system — just pick the right source and we handle the rest. DXF, CSV, Excel and Shapefile accept any of the 195 systems.
- How does the tool know my file’s coordinate system?
- GeoJSON, KML and GPX imply WGS 84 by spec, and shapefiles declare theirs in the .prj (auto-matched against the Arab-world registry). DXF, CSV and Excel carry none — you pick from 195 systems across 22 Arab countries.
- How is Arabic text in legacy shapefile tables handled?
- The .dbf table is read as UTF-8 first; if that fails we fall back to Windows-1256 (the legacy Arabic codepage) with a clear notice, and honour a .cpg sidecar when present. Exports are always UTF-8 with a .cpg included.
- How do polygons become GPX, or lines become Excel?
- GPX has no polygon type, so polygons export as closed tracks (inner holes dropped) with an upfront notice. CSV/Excel write lines and polygons into a standard WKT column that QGIS and ArcGIS read — nothing is ever dropped silently.
- Are elevations (Z values) preserved?
- Yes — Z values pass through every format that supports them. Reprojection is horizontal (no vertical datum transformation), the standard behaviour in surveying file exchange.
- What are the size limits?
- Up to 50 MB, 50,000 features and two million vertices — enough for very large survey jobs. Split bigger files and convert each part. The tool is free, no sign-up, no usage caps.
