Common whitespace problems
Text copied from PDFs, web pages, Word documents, or code editors often carries hidden whitespace: trailing spaces at line ends, double spaces between words, mixed Windows (CRLF) and Unix (LF) line endings, or non-breaking spaces ( ) that look like regular spaces but break matching.
The Full Clean preset trims every line, collapses multiple spaces, removes blank lines, and normalizes line endings — the most common combination for cleaning copied text before pasting into a database, CMS, or code file.
Clean Code Paste normalizes tabs to spaces and collapses blank lines, preserving structure while removing the junk that comes from copying from Slack, email, or web pages.
