About the Whitespace Cleaner tool
Fix pasted text in one click: trim each line, collapse runs of spaces and tabs, remove blank lines or compress them to at most one.
It deliberately leaves intentional indentation alone when collapsing is off — toggle individual options to keep the structure you need.
Everything runs locally in your browser: no data is uploaded, no account is needed, and it works offline once the page has loaded.
