How can I choose the fields and geometry in a GIS export?

Load GeoJSON, filter by geometry type and choose attribute columns. Preview the selected records, then export CSV, GeoJSON or a shapefile package. Shapefile field names are mapped to unique names within its ten-character limit, and text is encoded as UTF-8. Long values fail explicitly so you can omit the field or retain it in CSV/GeoJSON.

Make sense of your geography.

4 features · 4 fields selected. GeoJSON retains geometry and IDs; CSV contains attributes and geometry types.

The local background has country outlines, without street detail. Map segments are drawn in longitude/latitude space; routes crossing ±180° can appear across the map. Measurement calculations follow spherical geometry. Save your dataset before leaving.

Is this tool free, and are my files uploaded?

This tool is free with no account required. The work happens in your browser. Your input and files are not sent to a processing server.

What are the limits and details?

All processing stays on this device. The bundled country outlines are a small-scale reference with no street detail. Coordinates use longitude, latitude order. Local files preserve your work; automatic cloud storage is not included.

Limits: 2,000 features, 40,000 coordinates, 100 distinct attribute fields and 5 MB of GeoJSON. Conversions run in a cancellable browser worker.
