Questions and answers
Is my CSV uploaded?
No. The selected file is read and validated by JavaScript in your browser; this site has no upload endpoint.
What CSV quoting is supported?
Comma-delimited fields, quoted commas, and doubled quote characters are supported.
Does a valid result mean the shipment data is correct?
No. It means the checked structure and values passed these rules, not that the underlying facts are accurate.
