## `qmk format-json`
Formats a JSON file in a (mostly) human-friendly way. Will usually correctly detect the format of the JSON (info.json or keymap.json) but you can override this with `--format` if neccesary.
**Usage**:
```
qmk format-json [-f FORMAT] <json_file>
```
## `qmk info` ## `qmk info`
Displays information about keyboards and keymaps in QMK. You can use this to get information about a keyboard, show the layouts, display the underlying key matrix, or to pretty-print JSON keymaps. Displays information about keyboards and keymaps in QMK. You can use this to get information about a keyboard, show the layouts, display the underlying key matrix, or to pretty-print JSON keymaps.
