Simply open a project in Brackets, and select ```Convert indentation to spaces``` or ```Convert indentation to tabs``` from the ```Edit``` menu.


This will replace tabs with N spaces, and replace N spaces at the begining of each line with a tab (N being the tab length defined in the editor, 4 being the default).

```Convert 4-space indentation to tabs``` will replace 4 spaces at the begining of each line, regardless of editor defaults.

This will replace tabs with N spaces, and replace each group of N spaces with a tab (N being the tab length defined in the editor, 4 being the default).
