About converting tabs to spaces
Each tab becomes a fixed number of spaces
The converter replaces every tab character with the configured number of spaces, using 4 spaces by default. It does not calculate visual column alignment or inspect language syntax, so mixed indentation should still be reviewed in your editor or formatter.
A cleanup step, not a full formatter
Use it when a snippet, config file, or copied command needs spaces instead of tab characters before pasting elsewhere. The page only converts tabs to spaces; it does not convert spaces back to tabs or rewrite code style beyond that replacement.
