1. Open Velox Map Locator → Import / Export.
2. Upload the prepared CSV.
3. Map source columns to the corresponding Location fields.
4. Run the validation preview.
5. Review errors, warnings and the planned create/update behavior.
6. Correct the source file or mapping if the preview is not what you expect.
7. Confirm the import.

Chunked writes

The importer performs writes in chunks rather than attempting an unbounded single operation. This is more suitable for larger datasets.

Validate before confirming

Treat the preview as a required quality-control step. A clean preview is faster than reversing hundreds of incorrect Locations.
