Random JSON Generator
Generate sample JSON data with custom schemas and realistic random values
All processing happens in your browser. No data is sent to any server.
Why This Tool
Building a frontend before the API is ready? Testing a JSON parser? This tool generates random JSON data matching a schema you define — with realistic names, emails, numbers, and nested objects.
How It Works
Define your JSON structure with field names and types (string, number, boolean, array, object). Set the number of items and generate. Copy or download the result.
