Collapse runs of spaces, tabs, and blank lines into a single space (and trim), or strip all whitespace entirely. Great for cleaning copied text.
It replaces every run of whitespace with one space and trims the ends — ideal for reformatting.
It deletes every space, tab, and newline, producing one continuous string.
Collapsing can change indentation in code; use "remove all" only when you truly want no spaces.
