How it works

Convert CSV rows to JSON objects or flatten JSON arrays into CSV with live formatting and copy-ready output.

  • Toggle header handling and delimiter to match your file.
  • Escapes quotes and newlines so exported CSV stays valid.

Quick examples

JSON to CSV (tiny)
[{"id":1,"name":"Ada"}]
id,name\n1,Ada

Use header toggle off when your JSON is a flat array of values.

Mini FAQ

Can I change separators?

Yes, set the delimiter field before converting.

What if my JSON items are missing keys?

Missing keys become empty cells in the CSV output.

Do I need a header row?

Turn off header row for CSV without headings or when exporting value arrays.
