JSON Dummy Data Generator

Generate an array of fake JSON records from a schema you define — e.g. {“id”:”number”,”name”:”name”} — computed entirely in your browser.

Developer Tools

Define a JSON schema below (field name to field type) and generate an array of matching synthetic records, including nested objects and arrays.

Generated locally in your browser — nothing is sent to our server.

Supported types: number, id, first_name, last_name, full_name, email, phone, company, job_title, username, website, address, city, state, country, postal_code, date, datetime, uuid, boolean, currency, random_string, status, category
