How to Format JSON Online - AI ToolBox
JSON formatting matters because it makes structure visible, not because it looks prettier.
Paste the raw JSON
Start with the response, log fragment, or config payload you need to inspect.
Check the structure
Focus on arrays, nested objects, and the fields you care about.
Move to the next step
After formatting, decide whether you need validation, conversion, or documentation.
FAQ
Does formatting change the data?
No. Formatting changes readability, not the meaning of the JSON itself.
