FAQs
Which languages work best?
JSON gets perfect pretty-printing. JavaScript and CSS are handled by a brace-aware formatter that works well for typical code.
Can it beautify minified JavaScript?
Yes. The generic formatter breaks minified code at braces and semicolons and re-indents it, which makes minified scripts far easier to scan.
What happens with invalid JSON?
If the input is not valid JSON, the tool falls back to the generic brace-aware formatter instead of showing an error.
Is any of my code stored?
No. All formatting happens locally in your browser, and your code never leaves your device.
