Remove Extra Spaces
Collapse double spaces, strip trailing whitespace, convert tabs, and remove surplus blank lines — all in one pass. Useful before importing data, publishing copy, or committing text to version control.
What gets cleaned
- Multiple spaces between words collapse to a single space.
- Leading and trailing spaces on each line are trimmed.
- Tabs are converted to spaces, which prevents alignment breaking when the text moves between editors.
- Runs of blank lines collapse to a single blank line, preserving paragraph separation without the gaps.
Where stray whitespace causes real problems
Trailing spaces are invisible and cause a surprising amount of trouble. In a spreadsheet, "London " and "London" are different values, so lookups fail and pivot tables split one category into two. In a database, a trailing space in an email address breaks the login. In version control, trailing whitespace produces noisy diffs that hide the real change. And in Markdown, two trailing spaces are meaningful — they force a line break — which is why removing them can silently alter your rendered output.
The double space after a full stop
If your text has two spaces after every sentence, it was probably typed by someone trained on a typewriter, where monospaced letters needed the extra gap. Proportional fonts handle the spacing themselves, and every current style guide — Chicago, AP, MLA, APA — specifies one space. This tool collapses them automatically, which is the fastest way to modernise an inherited document.
