Understanding GeoJSON Formatter
Geometry and attribute translation
Validate, inspect, format, and minify GeoJSON locally in your browser.
GeoJSON Formatter translates geojson into geojson. Geometry and common properties usually transfer, while styling, CRS metadata and format-specific extensions may not have direct equivalents.
What to check after conversion
Conversion preserves supported geometry and attributes, but source-specific styling or metadata may not have an equivalent output representation. Review warnings and validate the result before replacing the source.
After GeoJSON Formatter, compare feature counts, geometry types, bounds and representative attributes with the source. Open the output independently before replacing or distributing the original file.
