How Factur-X / ZUGFeRD XML Extraction Works
Upload Your Hybrid PDF
Drag and drop a Factur-X or ZUGFeRD PDF. We detect the embedded XML attachment automatically, no matter which branding the file uses.
Parse & Extract
The embedded CII XML (factur-x.xml, zugferd-invoice.xml, or xrechnung.xml) is pulled byte-for-byte from the PDF/A-3 container. No transformation, no reformatting.

Why Extract XML from Factur-X or ZUGFeRD?
Factur-X and ZUGFeRD invoices embed structured XML inside a standard PDF, but many accounting systems can only process the raw XML data. Extracting the XML lets you automate data import, eliminate manual entry, and integrate invoice data directly into your ERP or financial workflows. Whether you're archiving, validating, or feeding data into a pipeline, the extracted XML gives you machine-readable access to every field in the invoice. The same extractor handles both formats, since Factur-X and ZUGFeRD 2.x share an identical PDF/A-3 + CII XML container.

Frequently Asked Questions
Does this work with Factur-X and ZUGFeRD?
Yes. Factur-X and ZUGFeRD 2.x use the same PDF/A-3 + CII XML container and are detected automatically. The extractor recognises all three spec attachment names, factur-x.xml, the legacy zugferd-invoice.xml, and xrechnung.xml (the ZUGFeRD XRechnung reference profile), and returns the embedded XML as-is.
What if my PDF has no embedded XML?
If the uploaded PDF does not contain an embedded CII XML attachment, use the AI Parse endpoint (/v1/parse/json) to read the visible invoice content, map it to the EN 16931 data model, and return structured invoice data.
What XML format is returned?
The extracted XML follows the UN/CEFACT CII (Cross Industry Invoice) format, the same syntax used inside Factur-X and ZUGFeRD files and one of the two official syntaxes of the EN 16931 European standard.
Is the extracted XML validated?
No. The XML is returned byte-for-byte from the PDF attachment. Pass it through /v1/validate/facturx, /v1/validate/zugferd, or /v1/validate/cii for a full Schematron validation pass.
