Free tool
E-invoice XML viewer
Paste a Peppol BIS, XRechnung or Factur-X (CII) document and get it cleanly indented and readable. It runs entirely in your browser — nothing is uploaded.
Check it, don't just read it
Send the same XML to the API for a full EN 16931 rule report:
curl -X POST https://fakturwire.com/v1/validate \
-H "authorization: Bearer $FW_KEY" \
-H "content-type: application/json" \
-d '{"xml": "<Invoice…>", "profile": "peppol-bis-3"}' Prefer a UI? Paste the same document into the free validator for a rule-by-rule report — or get an API key with 50 free credits →
