How to use the CSV to JSON Converter

  1. Paste your CSV (or JSON) data into the input box, or drag & drop / upload a file.
  2. Pick a delimiter, or leave it on auto-detect — the tool checks commas, semicolons, tabs and pipes.
  3. Toggle "array of arrays" if you want raw rows instead of objects keyed by the header row.
  4. Click "Convert" to run the conversion in either direction.
  5. Copy the result or download it as a file.

Why use ZillaKit's CSV to JSON Converter?

Spreadsheet exports are messy: quoted fields containing commas, embedded newlines, and inconsistent delimiters trip up naive converters. ZillaKit's CSV to JSON tool includes a small, correct CSV parser built from scratch that properly handles quoted fields, escaped quotes, and mixed line endings — all running locally in your browser. Nothing you paste or upload is ever sent to a server. Convert CSV exports from Excel, Google Sheets, or database dumps into clean JSON arrays of objects (using your header row) or arrays of arrays, and convert JSON back into CSV just as easily. It is free, fast, and requires no signup, making it ideal for quick one-off conversions or repeated daily use.

FAQ

Does this tool handle quoted fields with commas inside them?

Yes. The built-in CSV parser correctly handles quoted fields containing commas, newlines, and escaped double quotes ("").

How does delimiter auto-detection work?

The tool inspects the first few lines and counts occurrences of common delimiters (comma, semicolon, tab, pipe) to pick the most likely one. You can always override it manually.

Can I convert JSON back to CSV?

Yes, switch to the "JSON → CSV" tab, paste an array of objects or array of arrays, and click Convert.

Is my data uploaded anywhere?

No. All parsing and conversion happens locally in your browser. Your files never leave your device.

What if my CSV has no header row?

Enable "output as array of arrays" to skip header-based object keys and get raw rows instead.
