About Mock JSON Generator
Mock JSON builds an array of JSON objects from a compact schema: one "field: type" line (e.g. "id: int", "name: name", "email: email"). Known types include int, float, bool, name, email, username, phone, date, datetime, url, color, and uuid.
Set the record count and a minify option. Ideal for populating mock API responses or frontend test fixtures. It CREATES new data, unlike the JSON formatters/validators in other categories.
FAQ
Is any data sent to a server?
No. Mock JSON Generator runs entirely in your browser — everything is generated locally and never uploaded to our servers.
