How to use this tool
- Choose the number of groups, characters per group and the separator between them.
- Choose letters or numbers, add optional beginning or ending text and set the batch size.
- Generate your codes, then copy or download the complete list. The product key preset uses five groups of five characters.
Things to know
- These are newly generated codes for your own projects or sample data. They do not activate Windows, Office or other third-party software.
- Up to 16 groups of 32 characters. Random codes use browser cryptographic randomness; grouping and fixed text do not add randomness.
- Duplicate prevention applies only to this batch. Your own application must handle issuing, storing and validating its licences.
- Generate up to 10,000 codes at a time. Results stay in this tab and are never saved by the site.
- Copy or download the complete batch as text or CSV. Import the CSV column as text to keep leading zeros; formula-like CSV values receive a protective apostrophe.
