JSON Mock Data Generator
Paste one example record and get a list of realistic mock objects back — same keys and types, invented values. Pick how many. It all runs in your browser.

The JSON Mock Data Generator turns one example record into a whole list of realistic fake objects. It keeps your template's shape — the same keys and the same types — and invents believable values per type: names, emails, ages, cities, lorem words, booleans and numbers. Pick how many records you want. Everything runs locally in your browser, so your template never leaves your machine and the generated data is entirely synthetic.
Reproducible by default
The generator reseeds on every run, so the same template and count produce the same records — ideal for stable test fixtures and snapshot tests. Tweak the template or the count to get a fresh set.
For seed data, fixtures and demos
Use it to seed a database, populate a UI with many rows, mock an API response, or build a demo — without hand-writing arrays or exposing real data. Nested objects and arrays in the template are filled too. Want to turn the result into a table or insert statements? Pair it with JSON to SQL or open the PayloadIQ playground.
