About Mock / Fake Data Generator
Build a schema by adding fields and choosing a type for each — UUID, first/last/full name, email, username, phone, city, country, company, job title, street, zip, date, boolean, number, sentence, color, URL or IPv4. Set how many rows you need and export the result as JSON, CSV or SQL INSERT statements.
Great for seeding databases, testing UIs and writing examples. Everything is generated locally in your browser; no data is uploaded.
A users dataset
id: uuid · name: fullName · email: email · age: number
[{ "id": "…", "name": "Ada Khan", "email": "ada.khan@example.com", "age": 36 }, …]Switch the output to CSV or SQL, and set the row count up to 1,000.
