The detector searches the uploaded content for namespaces, profile identifiers, root elements and national format markers. It can distinguish many common UBL, CII, JSON and fiscal-document profiles without submitting the file to an external service.

What the tool checks

Root document and syntax family
Customization, profile and schema markers
National format signatures
Confidence level for each match

What it cannot confirm

Technical check only

A detected signature is not a complete schema validation
Unknown extensions may require the issuing platform
