How to Debug Common JSON Errors
Track down malformed JSON quickly using a formatter, validator and diff tool.
1. Validate the JSON first
Use the JSON Beautifier to validate and pretty-print any payload. Syntax issues stand out immediately.
2. Compare old vs new payloads
If something suddenly broke, load the old working response and the new one into JSON Diff to see what changed.
3. Isolate the problematic section
Trim your JSON down until the error disappears. This narrow slice is usually where the issue lives.
