Frequently asked questions
Can this tool fix invalid JSON automatically?
No. It validates JSON and shows parser errors so you can fix the source without guessing what changed.
What is the difference between format and minify?
Format adds readable indentation for review, while minify removes extra whitespace for compact snippets and payloads.
