Frequently Asked Questions
- How do I remove extra spaces from text online?
- Paste your text into the input box. The "Collapse spaces" option is on by default. Any run of two or more consecutive spaces is replaced with a single space. The cleaned output appears in the right panel immediately. Click Copy to put the result on your clipboard.
- How do I remove blank lines from text?
- Turn on the "Remove blank lines" option by clicking the checkbox. Any line that is empty or contains only spaces and tabs is deleted from the output. PDFs often insert blank lines between paragraphs. Removing them restores the flow of the text when pasting into documents or emails.
- What does "trim lines" mean?
- Trimming a line removes any spaces or tabs at its very start and at its very end. The content in the middle of the line is unchanged. Trimming fixes lines indented with spaces or lines where trailing spaces were accidentally added. The "Trim lines" option is on by default.
- What is the difference between trim and collapse spaces?
- Trim removes spaces only at the start and end of a line. Collapse replaces any run of two or more spaces anywhere in a line with a single space. Use trim to fix indentation. Use collapse to fix text where words are separated by multiple spaces instead of one.
- Can I remove tabs from text?
- Yes. Turn on the "Replace tabs" option. Every tab character in the text is replaced with a single space. Tab replacement helps when copying code or spreadsheet data. Tab characters become spaces so the text flows as normal prose.
What is Whitespace Cleaner?
Whitespace cleaner removes unwanted spaces, tabs, and blank lines from any block of text. Copied text from PDFs, spreadsheets, and web pages often contains extra whitespace. Five independent operations can be applied in any combination.
Available options: trim line edges, collapse multiple spaces, replace tabs, remove blank lines, trim the whole text. Each option is a checkbox you can toggle on or off. The output updates live as you change the settings.
How does it work?
Each cleaning operation runs as a separate string transformation in sequence. Tabs are replaced first, so the subsequent space operations also catch any spaces introduced by tab replacement. Line trimming runs next, removing spaces at the edges of each line. Space collapsing then reduces internal runs. Blank line removal filters the resulting lines. Final trim cleans the overall string boundaries.
The character count below the output shows how many characters were removed. A zero count means the text had no whitespace problems matching the selected options.
When should you use Whitespace Cleaner?
Use it after copying text from a PDF. PDF text extraction frequently adds extra spaces between words and blank lines between paragraphs. Pasting directly into an email or document looks broken without cleaning first.
Use it to clean data pasted from spreadsheets before importing. Some systems treat "Mumbai " and "Mumbai" as different values. Running the text through a trimmer first prevents these mismatches.
Tips to get the best results
- Keep "Trim lines" and "Collapse spaces" on for most cleaning tasks. Both options handle the majority of whitespace problems from copied text.
- Turn on "Remove blank lines" only when the blank lines are unwanted. Some text, like poetry or formatted lists, uses blank lines intentionally.
- If your text is code, be careful with "Collapse spaces". Code often uses multiple spaces for indentation, and collapsing them will break the formatting. Use a code formatter instead for source code.
- Use "Replace tabs" when pasting tab-delimited data into a system that expects space-separated values. Skip it for CSV or TSV data where tabs are the actual delimiter.
