About Trim Whitespace
The Trim Whitespace tool removes leading and trailing spaces, tabs, and other whitespace characters from every line in your text. Paste your content and get a clean result instantly — no manual editing, formulas, or scripts required.
Leading and trailing whitespace is a common problem in data exported from spreadsheets, copied from PDFs, pasted from web pages, or received from external systems. These invisible characters cause sorting errors, duplicate detection failures, and data matching problems.
The tool trims whitespace from both ends of every line simultaneously. It does not change spacing between words. Your text content remains intact.
Everything runs locally in your browser. Your data never leaves your device, and no account or sign-up is required.

Frequently Asked Questions
Does it remove spaces between words?
No — only leading spaces (before the first visible character) and trailing spaces (after the last visible character) are removed. Spaces between words are preserved.
Does it remove tabs as well as spaces?
Yes — tabs, spaces, and other whitespace characters at the start or end of each line are all removed.
Why does trimming matter for data processing?
Hidden whitespace causes 'apple ' and 'apple' to be treated as different values. This breaks deduplication, sorting, lookup formulas, and database queries. Trimming ensures consistent matching.
Can I trim only leading spaces or only trailing spaces?
The default mode trims both ends. If you need to trim only one side, use the Find & Replace tool with a regex like ^\s+ (leading) or \s+$ (trailing).
Does it normalize multiple spaces between words?
No — this tool only trims the ends of each line. To normalize multiple consecutive spaces within a line, use Find & Replace with regex: replace \s+ with a single space.
Should I trim before or after removing duplicates?
Trim first. Invisible trailing spaces cause 'apple' and 'apple ' to be treated as unique values, which defeats deduplication.
