About

Generate random nested JSON payloads to test parsers, validators, and API robustness.

Accepted input

Accepts raw JSON, JSON arrays, schemas, or diff inputs pasted into the editor. Invalid JSON is surfaced inline before any transformation runs.

How to use

Open Random JSON Generator and paste, type, or upload the input it expects.
Adjust the available options until the preview or output reflects the workflow you need.
Use copy, download, or related follow-up tools once the result looks correct.

Tips

Pair it with other json tools from the same category when you need a broader workflow.
Pinned tools and recent history make it faster to return to repeated workflows.
