What the Tabs to Spaces Converter does
Replace tab characters with a consistent number of spaces.
Set how many spaces each tab becomes and get evenly aligned text ready for style guides or diffs.
Why the Tabs to Spaces Converter is useful
Tabs may render at different widths across editors and can cause misaligned text or code.
Mixed tab widths make code review diffs noisy, so converting to spaces once keeps indentation consistent for everyone on the team.
