How to Clean Up Whitespace and Extra Spaces in Text

What the cleaner fixes

The tool tidies every line of your text: it trims spaces from the start and end of each line, and collapses any run of spaces or tabs inside the line down to a single space. So " Hello world " becomes "Hello world".

Removing blank lines

Tick the "Remove blank lines" option and every empty line disappears, leaving a compact list. Leave it unticked and blank lines are kept — useful when empty lines separate paragraphs you want to preserve.

Why messy whitespace matters

Extra whitespace causes real problems:

• Spreadsheets and databases treat "apple " and "apple" as different values
• Duplicate-line removers and sorters miss matches when spacing differs
• Code and config files can break on stray tabs or trailing spaces
• Pasted lists look ragged in documents and emails

Worked example

Paste in " Hello world " followed by two blank lines and " A cleaner list ". The result is "Hello world", the blank lines (or not, if you ticked the option), and "A cleaner list" — every line trimmed, every gap reduced to one space. Click Copy result to grab the cleaned text.

A tidy text workflow

Whitespace cleaning works best as the first step: clean the text, then run it through Remove Duplicate Lines to drop repeats, then Text Line Sorter to put it in order. Three free tools, one tidy list.
