Remove Empty Whitespace Online
Code with inconsistent indentation, text with double spaces after periods, and spreadsheet exports with invisible trailing spaces all carry horizontal whitespace problems that are easy to miss but cause real issues in editors, databases, and parsers. Paste your text here to fix spacing character by character without touching your line breaks or paragraph structure.

How it works
Paste your text into the input panel and toggle the options you need. Each toggle targets a specific type of horizontal whitespace independently. The line structure of your text—every line break and paragraph gap—stays exactly as it is unless you use the Nuclear option.
The whitespace toggles explained
Fix double spaces collapses any run of two or more consecutive spaces into a single space. This covers the classic double space after a period, extra spaces between words copied from a PDF, and any text that used multiple spaces for visual alignment.
Trim line ends removes invisible spaces and tab characters sitting at the end of each line. These trailing characters are completely invisible on screen but they show up in diffs, break certain parsers, and cause unexpected behaviour in version control systems and database imports.
Convert tabs to spaces replaces every tab character (\t) with a set number of spaces. If you need the opposite direction, the find and replace tool with regex can swap space indentation back to tabs.
Remove zero-width characters purges invisible Unicode formatting marks (like zero-width spaces or joiners). If you suspect your text is haunted by non-printing characters, run it through the normalize unicode tool as a follow-up.
Nuclear (Remove ALL) is the absolute override. It strips every single space, tab, and line break from your document, compressing the entire input into one continuous string of characters.
Who uses this and why
Programmers use it most for trailing whitespace. Most style guides and linters flag trailing spaces as errors. Cleaning them manually across a large file is impractical. Pasting the code here and running Trim line ends strips them all in one operation before the code goes into a review or gets committed.
Marketers run into double spaces constantly when editing drafts. Catching every instance by eye is slow and unreliable. For heavier data cleaning, running the output through the remove duplicate lines tool catches any rows that only differed by invisible whitespace.
