What do the coordinate columns contain?

One row per feature, with the geometry type and its coordinates written as text: a point is a pair, a line or polygon is a list. That keeps shapes with any number of vertices in a single cell.

Can I get the properties only?

Yes: delete the geometry columns after exporting, or filter them out in your spreadsheet. The CSV keeps every property as its own column.

GeoJSON to CSV Converter

Paste the GeoJSON or open a .geojson file, run the analysis, and export the feature list as CSV or Excel. Each feature becomes one row: its properties, its geometry type and its coordinates.

Features whose geometry is too nested to flatten are skipped and counted on the page, so a scan of the output is never a silent data loss. The file is parsed in your browser and never uploaded.

GeoJSON Viewer & Simplifier

Paste or upload a GeoJSON file to validate it, preview it on a map, shrink it with Douglas-Peucker simplification, and export it as GeoJSON, KML or CSV.

Your data never leaves this browser

The file is parsed, previewed and charted on your own device. Nothing is uploaded — not even a sample. Close the tab and the data is gone.

GeoJSON

Or pick a .geojson file

Simplification tolerance100 m

0 keeps every coordinate. Larger values drop points that sit within that distance of the line — handy before shipping a boundary file to the web.

Import a file to get started. Everything runs locally.

How it works

1.Paste a GeoJSON document or pick a .geojson file — nothing is uploaded.
2.Set the simplification tolerance if you want a smaller file: 0 keeps every coordinate.
3.Press Check and preview: you get the feature and coordinate counts, the bounding box, the property keys and any structural problem with its location.
4.Download the simplified GeoJSON, or the coordinates as CSV.
