Frequently Asked Questions
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.
