JSON Formatter / Validator
③ Data / Text
What it is: JSON is the most common data format for APIs and configs. Expand one-line JSON into a readable layout (or minify it) and check it is valid.
When to use: When an API returns a wall of cramped JSON, or you need to check that JSON is written correctly.

FAQ
What JSONPath syntax is supported?

Is my JSON sent to a server?
No. All processing happens entirely in your browser. Your data never leaves your device.
