Formatters are used for translating data formats between those used in for display and those used for storage.

Following is the list of built-in angular formatters:

- `boolean` - Formats user input in boolean format
- `json` - Formats user input in JSON format
- `list` - Formats user input string as an array
- `number` - Formats user input strings as a number
- `trim` - Trims extras spaces from end of user input
