Generate data to preview JSON…What this tool does
It generates realistic JSON records from a small schema so you can prototype UIs, test edge cases, and reproduce bugs faster.
When to use it
- UI prototyping and empty/loading states.
- Testing table/list rendering with realistic values.
- Creating sample payloads for bug reports.
Tips to get better mocks
- Include edge cases: empty strings, long names, and null-like values when applicable.
- Keep counts reasonable to avoid heavy renders.
- Format the output before sharing.
