  • Database seed generation

Privacy

CSV data is parsed entirely in your browser. No rows or column values are sent to a server.

Quick tips

  • The first row is treated as the header row.
  • Use auto-detect if you are unsure about the delimiter.
  • Combine with JSON Formatter to pretty-print the result.

How to use this tool

  1. Paste your CSV content or edit it directly.
  2. Select the correct delimiter or use auto-detect.
  3. Click Convert and copy or inspect the JSON output.

Common questions

Does the CSV need a header row?

Yes. The converter expects the first row to contain column names, which become JSON object keys.

Are quoted fields with commas handled correctly?

Yes. The parser follows RFC 4180 quoting rules so fields wrapped in double quotes are treated as single values.
