Text Cleanup and Whitespace Normalizer
Clean pasted text locally by trimming lines, normalizing spaces, tabs, blank lines, and line endings.
How to use this tool
Paste messy text from a document, spreadsheet, CMS, email, or log file.
Choose cleanup options such as trimming lines, collapsing spaces, converting tabs, and limiting duplicate blank lines.
Copy the normalized text for documentation, publishing, import scripts, or diff-friendly commits.
What text cleanup can fix
Whitespace cleanup can remove trailing spaces, normalize line endings, collapse repeated spaces, and reduce excessive blank lines.
This is useful before importing CSV-like text, preparing Markdown, cleaning copied website content, or comparing two text files.
It does not rewrite meaning or grammar; it only normalizes characters and spacing based on the selected options.
Avoid accidental data changes
Collapsing spaces can be wrong for code, fixed-width data, poetry, or legal text where spacing matters.
Review the output before replacing source content, especially when tabs or multiple spaces are meaningful.
For code formatting, use a language-aware formatter instead of a generic whitespace normalizer.
Examples
Trim and collapse copied text

Hello Lumio\n\nTools now
Prepare text before diffing
Normalizing line endings and trailing spaces can make diffs easier to read when content came from different editors or operating systems.
FAQ
Will this change words or punctuation?
No. It only changes whitespace according to the selected cleanup options.
Can this be used for code?
Only for simple cleanup. For real code formatting, use a language-aware formatter to avoid changing meaningful whitespace.
Does it handle Windows and Unix line endings?
Yes. It can normalize mixed line endings so copied text behaves consistently.
Is the text uploaded?
No. Cleanup runs locally in your browser.
