What does the JSON formatter do?

It takes raw or minified JSON and re-indents it with 2-space formatting so it is easy to read and navigate.

What happens when my JSON is invalid?

The validator will show you the exact parse error message, including the position of the syntax mistake, so you can fix it quickly.

Is my JSON data sent to a server?

Never. All formatting and validation happens entirely in your browser using JavaScript. Your data never leaves your device.

Is it safe to use Edita for sensitive files?

Absolutely. Edita processes all your files locally in your browser using WASM (WebAssembly) technology. Your documents never leave your device and are never uploaded to our servers, ensuring total privacy.

Does Edita store my data or file history?

No. We have a strict 'no-storage' policy. Once you close your browser tab, all traces of your processed files are gone. We don't track your content or keep any logs of your file data.

Why is Edita faster than other online converters?

Traditional tools require you to upload large files to a server, wait for processing, and then download them back. Edita eliminates all network lag by processing everything instantly on your own hardware.
