## Frequently Asked Questions

Is this Factur-X / ZUGFeRD (CII) test data free to use?

Yes. The rows are released under CC0-1.0, so you can copy, modify, and redistribute them without attribution.

Is the data real?

No. All rows are synthetic. Values are structurally shaped for the format and are clearly marked synthetic. They are not real accounts, patients, devices, or registrations.

How is the dataset generated?

Deterministically from a fixed seed, so the same size always produces the same rows. That makes it safe to pin in a fixture or CI pipeline.
