How to convert tabs to spaces in Notepad++

Author : Piyush Gupta

To convert existing tabs to spaces, press Edit->Blank Operations->TAB to Space.

If in the future you want to enter spaces instead of tab when you press tab key:

1. Go to Settings->Preferences...->Language (since version 7.1) or Settings->Preferences...->Tab Settings (previous versions)
2. Check Replace by space
3. (Optional) You can set the number of spaces to use in place of a Tab by changing the Tab size field.
