FAQ

    
How do I validate SEPA XML files?
Import (or paste) your SEPA XML and click Run. The tool checks well-formedness and reports the exact error location (line/column) with a snippet.
Does this validate against a SEPA XSD schema?
This tool validates XML well-formedness and provides diagnostics. Schema (XSD) validation requires the correct SEPA schema file/version and is not included in this lightweight checker.
What does the diagnostics report show?
It shows the error message, line/column (when available), a snippet with a caret, and practical fix suggestions based on the error type.
Can the tool repair my XML automatically?
It can remove invalid XML 1.0 control characters (often introduced by copy/paste). Structural issues (missing/incorrect tags) must be fixed manually using the diagnostics.
How do I copy or download the result?
Use Copy output to copy to your clipboard, or Download output to save it as an XML file.
Why is the tree view disabled for large files?
Rendering huge XML trees can freeze the browser. For large inputs the tool keeps the page responsive by disabling tree rendering while still validating and reporting diagnostics.
