JSON formatter
Check JSON, make it readable, or compact it for reuse.
02 / Your result
Your result will appear here.
Start with your own input or try an example.
What it does
Find a syntax error in a configuration file, inspect an API response, or make a JSON document easier to review. Format or compact your input without silently rounding large number tokens. Copy the output or save it as a file; compatible data can become a JSON applet draft in your dashboard.
Useful when
- Find a misplaced comma in a configuration file.
- Read an API response before building an integration.
- Prepare small JSON data for a hosted endpoint.
How to use it
- Paste JSON or import a .json file.
- Choose readable formatting or compact output.
- Check the result, then copy or download it.
A few useful details
Is this a JSON schema validator?
It checks JSON syntax, not a custom schema or whether the contents are correct for another service. It does not execute your data.
Are large numbers changed?
Formatting and downloads preserve number tokens as written. The dashboard handoff is more restrictive and is unavailable when parsing could change the data, including unsafe numbers or duplicate keys.
Does my JSON leave the browser?
No. Formatting happens locally. Saving a dashboard applet is a separate action you review in the workspace editor.
