Suppresseur d'espaces blancs

À PROPOS DE CET OUTIL

Paste text and remove leading and trailing spaces, collapse multiple spaces into one, or strip blank lines entirely. Especially useful when cleaning up copy-pasted content from PDFs, spreadsheets, or web pages. Text pulled from these sources often carries invisible extra spaces between words, stray tabs, or empty lines left behind by page breaks and cell formatting. This tool separates the cleanup into distinct options so you can trim only what you need — for example collapsing doubled spaces from a PDF without deleting the blank lines that separate paragraphs.

COMMENT UTILISER

1. Paste the text you want to clean into the input box
2. Select whether to trim leading/trailing spaces on each line
3. Select whether to collapse multiple consecutive spaces into a single space
4. Select whether to remove blank lines entirely
5. Copy the cleaned text once the preview looks right

CAS D'USAGE COURANTS

• Cleaning text copied out of a PDF where extra spaces appear between words due to justified formatting
• Removing repeated blank lines left behind when pasting from a spreadsheet cell into a text field
• Tidying code or config snippets copied from a chat app that added extra indentation spaces
• Preparing scraped web page text for a dataset by stripping inconsistent spacing before further processing
• Cleaning up pasted email content full of trailing spaces from a previous forwarding chain

CONSEILS ET ERREURS COURANTES

• Collapsing multiple spaces will also affect intentional spacing used for plain-text alignment, like ASCII tables, so avoid that option if formatting matters
• Removing blank lines entirely will merge paragraphs together with no separation — use paragraph-preserving trim options instead if you still want single blank lines between paragraphs
• Tabs and spaces are different characters; check whether the tool's options address tabs separately if your source text uses tab-indentation
• Trailing whitespace at the end of lines is often invisible in normal view but can break exact string matching or diffing tools, so it's worth running text through this before pasting into code

AUTRES QUESTIONS

What's the difference between trimming and collapsing whitespace?

Trimming removes spaces only from the start and end of each line, while collapsing reduces any run of multiple spaces within a line down to a single space — you can use either independently or both together.

Will this tool remove single blank lines used to separate paragraphs?

Only if you enable the option to strip blank lines. If you want to keep paragraph breaks, leave that option off and just use the trim or collapse settings.

Does it handle tabs the same way as spaces?

Tabs are a distinct whitespace character from spaces, so depending on the option selected, tabs at the start or end of lines are typically trimmed, but tab characters used mid-line for alignment may not be converted to single spaces automatically.

Can this fix inconsistent line breaks from copying across Windows, Mac, and Linux?

The tool focuses on spaces and blank lines rather than line-ending characters (like CRLF vs LF), so if you're seeing odd line-break behavior across operating systems, that's a separate issue from the whitespace this tool targets.
