WKT to GeoJSON Coordinate Review

Convert saved WKT to GeoJSON and review the declared longitude and latitude coordinates. Keep the unchanged WKT, complete GeoJSON and both original reports together in a ZIP for manual review.

• Use one UTF-8 WKT text file (.txt),or paste up to1 MiB. Declare longitude/latitude coordinates yourself:the flow does not infer CRS,SRID,units or reproject. The original converter accepts planar coordinates;the next original inspector refuses positions outside longitude±180/latitude±90. Review the complete original geometry and both reports. All7supported geometry types,consistent2D/Z and empty geometries are retained;the original conversion report keeps an empty WKT Z declaration that GeoJSON cannot express. Decimal spelling may normalize in binary64. Ordinary bounds are not a minimal antimeridian envelope. No topology,ring orientation,self-intersection,hole containment or mapping/import-readiness certification. Source and every native report remain private inside the ZIP;review before sharing. A valid first checkpoint can exceed the next1MiB source ceiling and remains downloadable when review refuses. Hash association is not signed authenticity.
