What is Trim Lines?
Trimming works line by line: it strips whitespace at the beginning (left trim), at the end (right trim) or both, and leaves the line breaks alone. It fixes copied lists with stray indentation, trailing spaces that break comparisons and sloppy exports.
Choose which side to trim, and optionally collapse runs of spaces inside each line into one. Indentation is removed only when you ask for it, so trimming only the trailing side keeps code-style indentation intact.
How does it work?
- Paste the lines you want to clean.
- Select trimming on both ends, at the start only, or at the end only.
- Tick "collapse repeated spaces inside lines" if needed, then copy the result.
Common use cases
- Removing trailing spaces from code or configuration before committing.
- Cleaning a list of values pasted from a spreadsheet before deduplicating it.
- Stripping indentation from copied Markdown or e-mail text.
- Normalizing lines before comparing two texts.

Frequently asked questions
How is this different from Remove Extra Spaces?

Are tabs and non-breaking spaces trimmed?
