# Tabs to Spaces Converter

> Convert indentation between tabs and spaces without disturbing alignment inside lines.

Converting indentation between tabs and spaces should only touch the leading whitespace on each line. Tabs or spaces used inside a line to align comments, table columns or string contents must be left alone or the alignment breaks — which is why this converter defaults to leading-only.

## FAQ

### Does the tabs-versus-spaces choice matter?

Only that a project picks one. Mixed indentation genuinely breaks Python and makes every diff noisy in other languages. Record the decision in .editorconfig and the argument stops being one.
