About BeispielWerk
Tools and explanations for everyone who needs sample and test data without using real data.
What the site is for
BeispielWerk offers a sample shop database, generators and validators for German identifiers such as the IBAN and the VAT ID, invoice numbers and test records. The audience is developers, testers, trainers and anyone who wants to fill forms, templates or demos with visibly invented values. The tools run in the browser; values you enter never leave your device.
Who runs the site
The operator is Ailiniyazi Maimaiti, 81739 München. Full details are in the imprint. The site started as a German-language project; the German version is at the home page.
How we work
Explanations rely on public sources, which are named on each page. The rules by which values are generated and the automated tests are described (in German) under Methodik und Quellen. The site does not give legal or tax advice.
To report mistakes or suggest improvements, write to kontakt@beispielwerk.de. Please do not send real IBANs, tax numbers or other personal identifiers; describe a problem with invented sample values.
