Întrebări frecvente

Does this validate my code for errors?

No — it only reformats spacing and indentation. Syntax errors in the original code will remain in the formatted output.

Is my code uploaded anywhere?

No. Formatting runs entirely in your browser using a bundled formatting library — nothing is sent to a server.

Can I adjust the indentation style?

The tool uses a standard 2-space indent, matching common style guides for web code.
