About JSON Formatter
Takes a wall of unreadable JSON and lays it out neatly as a tree you can fold and unfold. If it is broken, it tells you where. It can also squash it back down to the smallest version.
When people use it
- Reading a response from an API you are working with
- Finding the missing bracket in a file that will not load
- Anyone handed a config file that is one enormous line
- Checking a file is valid before sending it on
