About JSON Schema to Mock Data

This tool generates mock data from JSON Schema with configurable count, array strategy, localization preference, and generation history.

Key Features

  • Schema-driven Generation: Produces data based on type/constraint definitions.
  • Built-in Examples: User/product/API schema starters.
  • Generation Controls: Count, array strategy, null inclusion, Chinese-content preference.
  • History Tracking: Keep recent generated outputs for reuse.
  • Stats + Export: Type counts plus copy/download actions.

Steps

  1. Paste/load a JSON Schema.
  2. Configure generation options.
  3. Generate and review output.
  4. Format, copy, or download results.

Use Cases

  • Rapid sample payloads for integration.
  • Mock data for frontend development.
  • Structured test data in automation pipelines.

FAQ

Why does generated data differ from expectations?

Complex constraints may require richer schema details or manual post-rules.

Is generation history permanent?

Usually session-oriented; export important outputs when needed.
