JSON ↔ CSV Converter
Convert a JSON array of objects to CSV, or CSV back to JSON — live, with download, in your browser.
How to use
Paste a JSON array of objects with JSON → CSV selected, or paste CSV (first row = headers) and switch to CSV → JSON. It converts live as you type. Quotes, commas, and newlines inside fields are handled correctly, and Swap feeds the result back in. Everything runs locally.
