CSV to JSON, JSON to CSV, YAML & XML Converter Free

A clean two-pane converter for developers and analysts: paste or load CSV, JSON, YAML or XML on the left, get the converted result on the right. Includes JSON beautify and minify. Ideal for API payloads, spreadsheets exports and config files — and since it's local, fine for sensitive data too.

How it works

Choose the conversion — CSV→JSON, JSON→CSV, JSON↔YAML, XML→JSON, or JSON formatting.
Paste your data or load a file.
Click Convert and copy or download the result.

Frequently asked questions

How does CSV to JSON handle headers?

The first row is treated as column names, producing an array of objects — the format APIs and scripts expect.

Is nested JSON converted to CSV?

Top-level fields map to columns. Deeply nested objects are stringified into their cells, which keeps the conversion lossless.

Are my files uploaded to a server?

No. Every iConvertDoc tool runs entirely in your browser using JavaScript. Files are opened on your own device, processed locally, and never transmitted anywhere — you can even go offline after the page loads.

Is this really free? Any limits or watermarks?

Completely free — no sign-up, no daily limits, no watermarks, no premium tier hiding features.
