How to generate mock test data
- Add columns and choose a data type for each.
- Set the number of rows.
- Choose an output format (JSON, CSV, or SQL).
- Generate and copy the result.
How this works
Data is generated from curated name/word lists and randomized number/date logic entirely in your browser — no data is ever real, and nothing is uploaded or sent to a server.
Common use cases
- Generate realistic sample data for testing a database or API
- Create mock JSON or CSV data for a demo or prototype
- Populate a test database with sample records
