Frequently Asked Questions
Does this identify where JSON syntax errors are located?
Yes, if invalid JSON is provided, the exact line and character offset is highlighted with clear error explanations.
What does it do with invalid JSON?
It shows a clear error pointing to the problem, so you can fix it — then format the valid result beautifully.
Can I minify JSON too?
Yes. Besides pretty-printing with 2 or 4 spaces, one click condenses JSON to a single compact line.
