How to remove whitespace
- Paste your text into the box above.
- Pick a mode. Extra spaces is the safe everyday choice.
- Pick Leading or Trailing to trim only one side of each line.
- Pick All whitespace only when you need one unbroken string.
- Copy the result or download it.
Five whitespace modes
- Extra spaces turns tabs into spaces and shrinks runs to one. It trims line ends too.
- The Leading mode removes indents from the start of every line.
- The Trailing mode removes hidden spaces at the end of every line.
- Blank lines: drops empty lines and leaves the rest alone.
- All whitespace: removes every space, tab and line break.
- A report of how many whitespace characters the tool removed.
Why remove whitespace?
Extra spacing comes from everywhere. Text from a PDF carries indents from the page layout. Spreadsheet exports pad values with trailing spaces. Word processors leave double spaces after periods. That habit comes from the typewriter days. Text copied from a website brings its own formatting along.
Spaces at the end of a line cause the most trouble because you cannot see them.
- A cell with "London " does not match "London" in a lookup.
- An email address with a trailing space fails a form check for no visible reason.
- A password field with a stray space rejects a password that looks right.
A cleanup fixes a whole group of bugs that are otherwise maddening to find.
Pick the right mode to remove whitespace
| Mode | Best for |
|---|---|
| Extra spaces | Everyday cleanup that keeps structure |
| Leading | Flattening indented text such as quoted emails |
| Trailing | Data before an import |
| Blank lines | Closing up double spaced text |
| All whitespace | One unbroken string for checks and hashes |
Be careful with all whitespace mode
It does exactly what it says. Every space, tab and line break disappears. "the quick brown fox" becomes "thequickbrownfox." You cannot rebuild the original from the result. The positions of the spaces are simply gone.
That makes it useful for a small set of jobs. Think of palindrome checks, hash inputs or comparing two strings while you ignore formatting. It ruins anything you plan to read. Keep your original text if you might want it back.
Why the tool converts tabs
Extra spaces mode turns tabs into single spaces. That suits normal writing. It breaks anything where tabs carry structure. Indented code is one example. A TSV file is another because the tab separates the fields.
For code and tab separated data, use Leading or Trailing mode instead. Those modes leave tabs inside each line alone.
One space or two after a period?
One. Two spaces came from typewriters where every letter had the same width. Modern fonts made the extra space useless. Every modern style guide asks for a single space. Extra spaces mode fixes double spaces for you.
Common whitespace problems and fixes
My code lost its indents
Extra spaces mode collapsed them. Use Trailing mode for code instead.
Some spaces will not go away
They may be special non breaking spaces from a web page. Run the text cleaner first. It turns those into normal spaces.
My paragraphs merged together
You picked All whitespace. Undo by pasting the original again and pick Extra spaces.
Remove whitespace before a data import
Imports fail in quiet ways when values carry stray spaces. A product code with a trailing space creates a duplicate record. A customer email with a leading space fails to match an account. Run the column through Trailing mode first. Then paste it back into your sheet. Your import will match records the way you expect.
Tips to remove whitespace safely
- Start with Extra spaces and check the result.
- Use Trailing mode on code and tab separated data.
- Save your original before you try All whitespace.
- Clean special spaces with the text cleaner first.
- Count characters before and after to see the change.
Who uses a whitespace remover?
Data teams clean values before imports. Developers trim strings and config files. Writers fix double spaces in old documents. Marketers tidy email lists. Office staff clean text pasted from PDFs.
Your text stays private
The tool works inside your browser. It sends nothing to a server and keeps no copy. Customer lists and code stay on your device. Need to join broken lines too? Use the line break remover. Want unique lines only? Try remove duplicate lines. Need a count after cleanup? The character counter helps.
