Fix Broken API JSON Before It Breaks Your App
Repair malformed API responses, validate the syntax, and inspect the cleaned payload before it reaches production code.
Why this workflow matters
Copied API payloads often contain trailing commas, smart quotes, comments, or truncated objects. This workflow gets the response back into valid JSON quickly so you can debug the real problem instead of fighting the parser.
What success looks like
- Stop parser crashes caused by malformed payloads.
- Get a valid JSON document you can share, diff, or feed into other tools.
- Move from syntax cleanup to actual API debugging in one pass.
