About this tool

Parse comma-separated CSV locally. The first row supplies object property names and every following value remains a string, so identifiers such as 00123 are not changed.

Common uses

  • Convert exported spreadsheet rows into JSON
  • Handle quoted commas, escaped quotes, and multiline fields
  • Preserve Unicode and empty fields without type inference
