WHAT IS CSV TO JSON?

Convert a CSV table to pretty-printed JSON. Quoted commas, escaped quotes and quoted newlines are handled correctly.

How to use?

  1. Paste or upload your CSV (first row as headers).
  2. Click Convert and review the resulting JSON.
  3. Copy or download it.

Frequently asked questions

Can it correctly parse a CSV cell containing a comma or a newline?

Yes — it uses a mature CSV parser that correctly handles quoted commas, escaped quotes, and cell values that span multiple lines, instead of naively splitting on every comma.

Will numeric-looking values become JSON numbers or stay strings?

They stay strings — CSV has no type system of its own, and guessing types risks corrupting data like a zip code "007" or phone number by stripping leading zeros or symbols.

What if a row has fewer fields than the header?

That row's resulting object simply omits the key for the missing field — it doesn't fabricate a value, and it doesn't fail the whole conversion.

Conversion runs entirely in your browser — nothing you paste or upload here is sent to any server.
