Geometry Repair Workbench
Check GeoJSON shapes for errors such as crossing polygon edges. Try repairs and compare the results before using the new file.
How can I repair an invalid GeoJSON shape?
Add your GeoJSON and run the check. The report shows which shapes are invalid and whether the repair worked. A repair can split or change a shape, so inspect the new geometry before using the downloaded copy.

What are the limits and details?
Use GeoJSON with at most 1,000 features and 100,000 coordinate positions. Review repaired geometry: self-intersections may become multiple polygons or collections. Coordinates use x/y order; reprojection does not add missing elevation data.
Limits: one file up to 8 MB; 500,000 characters per text field. One job runs at a time on the worker, with a two-minute limit.
