CSV to JSON converter

Convert CSV to JSON or JSON to CSV, live as you paste - nothing ever leaves your browser.

Drop a file here, or choose one.

Runs fully in your browser. Nothing is uploaded.

How it works

  1. Paste your CSV or JSON.

  2. Pick a direction: CSV to JSON, or JSON to CSV.

  3. Copy the result.

Frequently asked questions

No. Everything is converted entirely in your browser.

No. Every CSV value stays a string, so a leading-zero ZIP code or a phone number is never silently corrupted into a number.

You'll see a clear message asking for an array of objects (or a single object) instead of a generic error.
