About this tool

Made for the task at hand.

Transform a header-based delimited file into an array of JSON objects. The parser follows quoted-field rules, including doubled quotes and multiline cells, instead of splitting every line naively.

How to use

  1. Paste CSV with a unique header row and at least one data row.
  2. Select the delimiter used by the source data.
  3. Resolve any row-width or quoting error and copy the JSON array.
Your work stays yours.

Common questions
Are numbers and booleans converted automatically?

No. Every cell becomes a JSON string, preventing accidental loss of leading zeros or changes to identifiers.

Can a quoted cell contain a newline?

Yes. Quoted multiline fields and doubled quote escapes are supported; inconsistent row lengths are rejected.
