Practical Guide
How to use JSON Cleanup Tool
When an API response is difficult to read, paste the JSON here to request a formatted version and a check for obvious syntax problems. Keep the original payload so you can compare changes.
Useful situations
- Inspect a nested API response before debugging a failing request.
- Identify potential syntax problems in a copied configuration object.
- Turn a compact payload into an easier-to-review structure.
Step-by-step workflow
- Paste a JSON object or array, including any broken section you want reviewed.
- Run the tool and compare the proposed correction with the source.
- Validate the returned JSON in your application before using it.
Sample input to try
Use the Load example button in the playground, or copy this input and adapt it.
{"customer":{"id":12,"active":true,},"tags":["trial","web",]}
Important: AI-generated corrections can change intended values. Do not assume malformed JSON can always be repaired unambiguously.
