Sublime Text 3, convert spaces to tabs

Question

I know there are a lot of posts about this, but I couldn´t get it to work.
I use tabs for coding. Is there a way, to convert always spaces to tabs? I.e. on open and on S

You can use the command palette to solve this issue.

Step 1: Ctrl + Shift + P (to activate the command palette)

Step 2: Type "Indentation", Choose "Indentation: Convert to Tabs"
