Whitespace & Indentation Cleaner

Clean up messy text or code in one paste. Strip trailing whitespace, collapse runs of blank lines, swap tabs for spaces (or vice versa), normalize CRLF/LF/CR line endings, and replace weird Unicode spaces with plain ASCII — with live before/after stats and toggleable rules so you only touch what you want.

Introduzione allo strumento

Panoramica dello strumento

Whitespace bugs are the silent productivity drain — emails with double spaces, code reviews with mixed indentation, CSV exports with no-break spaces hiding in cells. This tool gives you a focused interface for the common cleanups: trim each side independently, collapse internal runs, drop or merge blank-line gaps, convert between tab and space indentation at any width, and rewrite line endings to LF, CRLF, or CR. Everything runs locally.

FAQ

Will this corrupt strings inside code?+

Be careful with 'collapse internal spaces' and 'spaces to tabs' on code that has spaces inside strings or significant alignment — those run on every character including string contents. For most cleanups, trim and blank-line rules are safe.

What counts as a Unicode space?+

No-break space (U+00A0), em/en spaces, thin space, hair space, zero-width space, ideographic space, and similar — all the troublemakers that look like regular spaces but break grep, diff, and CSV parsing.

Why might I want CR or CRLF endings?+

CRLF is the Windows default and is required by some Windows-only tools and protocols. CR is the classic Mac OS 9 ending and rarely useful today. LF is the modern default for Linux, macOS, and most build tools.

Is my text uploaded?+
