Whitespace / Extra Space Remover

The Whitespace / Extra Space Remover cleans up messy pasted text by trimming leading and trailing spaces from every line, collapsing repeated spaces into one, and optionally deleting blank lines entirely. It's the tool for the moment right after copying text from somewhere that adds invisible padding — indented email replies, spreadsheet cells with trailing spaces, or a document with inconsistent spacing from years of manual edits.

It comes up constantly in data cleanup: preparing a list of names or emails for a bulk import where trailing spaces would break an exact-match lookup, tidying up code or config text pasted from a formatted source, and cleaning a block of prose before running it through a word counter or spell checker where extra spaces would throw off the numbers. Because whitespace is invisible, these issues are easy to introduce and hard to spot by eye — a trailing space at the end of a spreadsheet cell looks identical to no trailing space at all until something downstream breaks.

Each of the three cleanup passes is independent and toggled separately: trimming removes only leading/trailing whitespace on each line, leaving internal single spaces alone; collapsing repeated spaces turns runs of two or more spaces or tabs into a single space, which fixes text that was manually aligned with the spacebar; and removing blank lines strips lines that are empty or contain only whitespace, useful for collapsing double-spaced text or removing gaps left by a bad copy-paste.

The three options can be combined or used alone depending on what's actually wrong with the input — collapsing spaces without removing blank lines keeps paragraph structure intact while still fixing internal spacing issues, for instance.
