What Spaces to Tabs can do:

This tool takes blocks of spaces and swaps them out for tab characters. You decide how many spaces count as a tab, and it handles all lines live. It’s useful when cleaning up indented text, fixing formatting in scripts or data files, or prepping text for editors that prefer tab characters. The live counter below the output tells you how many lines were processed. With file import, maximize toggle, and export buttons, it’s a handy quick-fix for space-heavy formatting.

Example:

Input:

Line    with    spaces
Indented line

Spaces per tab:

4

Output:

Line	with	spaces
	Indented	line

Common Use Cases:

The Spaces to Tabs Tool converts groups of spaces into tab characters based on your specified space width. It’s ideal for reformatting code, aligning text for cleaner indentation, preparing text files for development or publishing, converting legacy documents to tabbed layouts, and making structured data easier to read and manage.
