When this tool helps
Use this tool when copied lines contain unwanted spaces before or after each value.
It is useful before deduplication, sorting, spreadsheet import, keyword list cleanup, or matching text values between tools.
Common cleanup options
Leading spaces
Remove accidental indentation before list values, keywords, names, or exported fields.
Trailing spaces
Clean hidden spaces that can break matching, imports, or comparison work.
Internal spaces
Optionally collapse repeated spaces inside each line.
Line order
The tool keeps the original order unless you use a separate sorting tool.
How to use it
- Paste text with extra spaces.
- Choose whether to collapse repeated internal spaces.
- Choose whether to remove empty lines.
- Run the tool and review the cleaned output.
Privacy, review, and limitations
The current version processes pasted text in your browser for normal use, and the page explains the tool behavior that is visible in the interface. Review the preview before copying output into another workflow, especially when the source text came from PDFs, spreadsheets, exports, or copied tables.
Trimming is text-based and does not validate whether a value is correct.
Intentional indentation should be reviewed before trimming source code, outlines, or formatted text.
Frequently asked questions
What whitespace does this trim?
It removes leading and trailing spaces or tabs from each line.
Can it collapse repeated spaces inside a line?
Yes. Turn on internal space cleanup when copied text contains repeated spaces between words.
Will it change line order?
No. Trimming keeps the original line order.

How this page is maintained
This tool page is maintained for practical accuracy, clear limitations, browser-based processing behavior, and links to related cleanup tasks. It is intended for everyday text cleanup, not for legal, medical, financial, security, or other high-stakes decisions.
Browser-local processing
The current tool runs in the browser and does not require an account, upload, or server-side text processing for normal use.
Reviewed behavior
Examples, options, and limitations are checked against the actual tool behavior before public pages are added to the site.
Human review still matters
Text cleanup can miss source-specific issues such as broken words, malformed data, or copied table artifacts, so review important output before reuse.
Safe use checklist
- Use sample or non-sensitive text when testing a workflow.
- Check the output preview before copying it into another system.
- Keep confidential, regulated, or customer data inside approved tools.
- Use related tools only when they match the same cleanup task, not to force unrelated edits.
