How to use
Paste the block, trim each line, then copy the cleaned result.
- Paste the line-based text that has extra spaces or tabs at the edges.
- Click Trim Lines to clean every line without changing the order.
- Copy the output back into your editor, config, or spreadsheet.
Use cases
This helps when the content is fine but each line carries messy edge whitespace.
- Clean copied code snippets or config lists before reuse.
- Fix line-based data before comparing it in diffs or reviews.
- Remove accidental edge spaces from pasted content blocks.
When this tool is useful
Use Trim Lines to clean whitespace around every line in a block of text while preserving the original line structure. Trim Lines sits in the text cleanup part of the site, which focuses on whitespace fixes, blank-line cleanup, and quick copy-paste repair.
It is especially helpful when copied text carries hidden spacing, uneven line breaks, or formatting noise from PDFs, email threads, exports, or CMS editors. Within that group, it leans toward whitespace cleanup tasks, so the page is tuned for quick single-purpose use rather than a long multi-step workflow. If this step is only part of the job, the most relevant follow-up tools are Remove Empty Lines and Duplicate Line Remover.
Before you copy the result
- Check that the cleaned output keeps the structure you still need, such as paragraph breaks or one item per line.
- Scan the first and last lines after processing so whitespace or accidental blank lines do not slip through.
- If you need one more formatting step, move straight into a related text cleanup or conversion tool instead of editing by hand.
