About this tool
Developers need to read API responses easily. This tool turns compact text into an indented structure and reveals errors such as a trailing comma or a missing quote.
No JSON is sent to a server, which matters when you handle sensitive data.
Frequently asked questions
Why do I get a JSON error?
Common causes: a trailing comma, single quotes, or a key without quotes.
What is minifying for?
