Purpose
Parse XML, report structural errors, and apply consistent indentation.
How it works
A DOM parser builds a valid document tree before formatting; whitespace in mixed content may be meaningful and cannot always be rewritten safely.
Input
Enter text, numbers, a file, or a query target as required. Start with the page example to confirm the format, then replace it with your data.
Interpreting output
Confirm output format, units, and status, then compare with the input and target environment; successful formatting does not prove validity.
Limitations and privacy
This tool processes input locally in the browser and does not send it to the server.
