What is Mock Data?
A mock data generator for building test datasets. Choose the columns you need, set the row count, and export the result as CSV or JSON.
How it works
Each selected field is generated with a deterministic, seedable generator (or @faker-js/faker), assembled into rows, and serialized to CSV or JSON.
- Enter your input. Type or paste your input into the field above — the tool responds instantly.
- Review the result. Output updates live as you type. Everything runs entirely in your browser.
- Copy or download. Use the Copy button to grab the result, or Download to save it as a file.
