Frequently Asked Questions

Why convert tabs to spaces?
Spaces render identically across editors and platforms, avoiding the inconsistent display that tabs can cause.
Can I convert only leading whitespace?
Yes. Enable leading-whitespace-only mode and only indentation will be converted, leaving in-code whitespace intact.
