About CSV

CSV is a flexible but loosely-defined format. This toolkit uses PapaParse under the hood to handle quoted fields, custom delimiters, and round-tripping JSON to CSV.

  • Quote fields containing commas or newlines.
  • Use TSV when fields might contain commas.
  • Skip the header row for data-only files.
  • Detect delimiter heuristically when unsure.
