Frequently Asked Questions

Is my data secure?

Absolutely. jtools.app performs all formatting locally in your browser. Your JSON data never touches our servers. We value developer privacy and data integrity.

What JSON specs are supported?

We support standard RFC 8259 JSON. Our tool handles large files, nested structures, and provides helpful syntax error pointing for quick debugging.

Can I format nested arrays?

Yes, the formatter recursively beautifies arrays and objects regardless of depth, ensuring consistent indentation throughout your document.

How do I minify JSON?

Simply paste your code and click the "Minify" button in the action bar. This will remove all whitespace and newlines to compress the payload.
