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.
Examples
Demo data generation
Generate a mock CSV dataset with names, emails, dates, and numbers — configurable rows and columns for demos and load tests.
Common mistakes
Column types are fixed
The column schema is fixed by the template — pick the template that matches your demo's data shape.
Frequently asked questions
What formats can it export?
CSV and JSON, with row counts up to tens of thousands.
