How to use Spaces to Tab

Paste text with space-based indentation and set the group size, and the tool converts each matching group of spaces back into a tab character.

Frequently asked questions

Which spaces get converted?

Only space groups at the start of lines (indentation) are typically converted.

You can choose whether to convert all space groups or only leading indentation.
