Clean text

Remove unwanted spaces and empty lines from text copied out of a document, an email or a web page. You choose exactly which corrections to apply: trimming spaces at the start and end of each line, collapsing repeated spaces and tabs, or deleting empty lines. The result is produced locally in your browser and can be copied or downloaded.

The tool offers three independent options, all switched on by default. The first removes spaces at the start and end of every line. The second replaces any run of ordinary spaces or tabs with a single space. The third deletes lines that are completely empty once the other options have run. Line breaks are normalised first, so text coming from Windows or another system ends up with consistent line endings. To keep the indentation of a code snippet, switch off line trimming and space collapsing: those characters can be part of the syntax. Likewise, keep empty lines when they separate paragraphs or blocks of data. This cleaner does not fix spelling or punctuation, does not change letter case and has no option for removing repeated lines; use the dedicated tool to deduplicate a list. Start with a small extract when you work with Markdown, CSV or any data whose layout carries meaning, and check the result before copying it or downloading the text file. Before cleaning structured text, choose the options one by one. A list of names usually tolerates collapsed spaces, whereas a code extract or a table aligned with tabs may depend on them. After processing, review the passages where line breaks and indentation have a particular meaning.
