FAQ

What formats does this pretty print converter support?

It supports JSON, XML, and SQL. Auto-detect chooses a format based on the first non-space character.

Does this tool upload my data to a server?

No. Formatting runs locally in your browser and the tool does not make network requests.

Why do I see a JSON error?

JSON must be strictly valid (double quotes, no trailing commas). Fix the reported issue and run Pretty Print again.

Can I sort JSON keys for stable diffs?

Yes—enable “Sort JSON keys” to recursively sort object keys before output.

Is the XML formatter a validator?

It parses XML to check well-formedness, then formats it. For complex edge cases, use a dedicated XML validator.

How does SQL formatting work here?

It applies lightweight spacing and line breaks around common clauses. It won’t fully understand dialect-specific syntax.

How do I quickly format using the keyboard?

Use Ctrl/⌘ + Enter to Pretty Print, and Ctrl/⌘ + M to Minify.
