Private by design. This tool runs entirely in your browser — nothing you enter or add is uploaded to any server.
How it works
- Paste your CSV or TSV content.
- Select the delimiter and whether the first row contains column names.
- Click Convert to JSON to produce an array of objects (or arrays if no headers).
Examples
- A header row plus data becomes [{ "name": "Ada", "role": "Engineer" }, ...].
- Without headers you get arrays of values: [["Ada", "Engineer", "98"], ...].
- Quoted fields containing commas are preserved correctly.
Frequently asked questions
Does it handle quoted commas?
Yes. Standard CSV quoting rules are followed so commas inside quotes stay inside the field.
What if my CSV has empty lines?
Empty lines are skipped. Trailing empty fields are kept.
Is the data uploaded?
No. Conversion runs completely in your browser.
