Factur-X / CII Validator

Run a local structural precheck on Cross Industry Invoice XML before it moves into a stricter hybrid invoice workflow.

Local precheck only. This page does not claim EN 16931 or legal compliance certification.

Drop a CII or Factur-X XML file here, or choose a file.

This precheck looks for the core signs users need first: CII root markers, hybrid markers, document identity, parties, and totals.
