About this tool
JSON is the standard format for sending data between apps and APIs, but raw JSON can be impossible to read when it arrives on a single line. Formatting adds indentation so you can see the structure at a glance.
The validator catches common mistakes such as trailing commas, single quotes, missing brackets and unquoted keys, and tells you where the error is. Minifying removes all whitespace to make a payload as small as possible. Everything is processed on the server and not stored.
Frequently asked questions
What are common JSON errors?
Trailing commas, single quotes instead of double quotes, unquoted keys and missing closing brackets.
What does minify do?
It removes all spaces and line breaks so the JSON is as small as possible. The data stays the same.
Is my JSON stored?
No. It is processed to give you the result and not saved.
