GeoJSON is the standard format for web maps, but spreadsheets, databases and analysis tools usually want a flat CSV table. This tool flattens your GeoJSON into CSV: one row per feature, the properties spread across columns, and the geometry written into a single column as WKT (the text geometry format of PostGIS and QGIS).
Every property key found across all features becomes a column, so nothing is lost even if features carry different attributes. The geometry of each feature - point, line or area - is written as WKT in the geometry column, which keeps the full geometry round-trippable; the partner tool CSV to GeoJSON reads it straight back.
Everything runs entirely locally in the browser - your possibly sensitive location data never leaves your device. Honestly framed: the geometry travels as WKT text in one column rather than as separate map columns, so the table stays tidy and lossless. An invalid or empty GeoJSON is rejected with a clear message.

Limitations: Converts GeoJSON to a CSV table: one row per feature, columns are the union of all property keys plus a geometry column holding the geometry as WKT. Coordinates WGS84. Round-trips with CSV to GeoJSON. An invalid or empty GeoJSON is rejected with a clear error.
In a single geometry column as WKT (e.g. POINT (13.4 52.5)), so every geometry type round-trips losslessly.
Every property key across all features becomes its own column; features missing a key get an empty cell.
Yes, use the partner tool CSV to GeoJSON; it reads the WKT geometry column (or latitude/longitude columns) back.
No, the conversion happens entirely locally in the browser; location data never leaves your device.
