FAQ
What formats does this online formatter support?
JSON, XML, HTML, CSS, SQL, and plain text (whitespace cleanup). You can pick a format or use Auto-detect.
Is my data uploaded to a server?
No. Formatting runs entirely in your browser and the tool does not send network requests.
Why does it say “Invalid JSON” or “Invalid XML”?
The input can’t be parsed (often due to missing commas/brackets in JSON or mismatched tags in XML). Fix the syntax and try again.
Can this tool fix broken JSON/XML automatically?
No—this tool formats valid input. It will show an error when parsing fails.
Does SQL formatting understand strings and comments?
It’s a lightweight formatter and may not handle every edge case (especially complex queries). For strict SQL-aware formatting, use a dedicated parser-based formatter.
Why did my HTML change when minifying?
Minifying collapses whitespace, which can affect text nodes in some HTML. If whitespace is significant, use Format instead of Minify.
How do I quickly format without clicking buttons?
Press Ctrl+Enter (Windows/Linux) or Cmd+Enter (macOS) to run Format.
