How to Format JSON for API Debugging

1. Capture the Raw Response

Grab the exact payload from devtools or logs, then paste it into the JSON Formatter to reveal structure and syntax problems.

2. Validate and Minify

Send the beautified payload through the JSON Minifier if you need to ship it over chat or store fixtures. When stakeholders only need CSV output, pipe it into the JSON to CSV converter for schema validation.

3. Compare Versions

Use Text Compare to highlight differences between failing and healthy payloads. This makes regression causes obvious for reviewers.

4. Decode Embedded Data

Run suspicious strings through the Base64 Encoder/Decoder or URL Decoder to spot double-encoding.

5. Share Evidence

Attach screenshots plus links to this article and the Developer Tools hub so QA, product, and support teams can replicate the fix.
