How it works
The input is parsed locally with quote-aware CSV parsing, so commas and line breaks inside quoted fields are preserved. Each column is then written to the output in the order you choose, with unchecked columns removed and renamed headers applied. Missing cells in short rows become empty fields, and the result is written back as standards-compliant CSV with your original delimiter. Nothing is sent to a server.
