FAQ
Should I format JSON before validating it?
If the payload is very dense or hard to read, formatting first can make the validation problem easier to spot. If you already know the data is malformed, validating first is also reasonable.
Do these tools replace each other?
No. Formatter improves readability, while validator confirms whether the parser accepts the content.
When do I need both tools?
You often need both when a payload is dense, unfamiliar, and likely to contain an error.
