Coordinate List Cleaner

Parse decimal or DMS coordinates, review likely swaps, normalize precision, and remove duplicates without network access.

Local syntax processing only: no geocoding, datum transformation, map lookup, or network request occurs. Coordinates are treated as WGS 84-style latitude/longitude values but their real-world accuracy and datum cannot be verified. Swap suggestions are never applied silently.

Coordinate list

Quote CSV DMS values containing spaces or commas. Whitespace mode is best for decimal or colon-form DMS. Up to 2,000 rows and 100 fields.
