关于 删除多余空格
Remove Extra Spaces cleans up your text by collapsing multiple consecutive spaces into a single space and trimming leading and trailing whitespace from each line. This is a common problem with text copied from PDFs, Word documents, web pages, or exported data where formatting artifacts introduce unwanted double or triple spaces.
The tool processes your text in real time, replacing any sequence of two or more spaces with a single space on every line. Line breaks and paragraph structure are preserved, so your content remains properly formatted after cleaning.
All processing runs locally in your browser with no data sent to any server. This tool is particularly valuable for sanitizing API inputs, cleaning CMS content before publishing, or normalizing imported data before database insertion.

故障排除
Expecting tab characters to be removed or converted
解决方案
This tool collapses consecutive spaces but does not remove or convert tab characters. To remove tabs, use the Clean Text tool or a Find & Replace operation targeting the tab character.
Non-breaking spaces (\u00A0) not being collapsed
解决方案
Non-breaking spaces are a different Unicode character from regular spaces and are not collapsed by this tool. Use the Clean Text tool to normalize non-breaking spaces to regular spaces first.
Indentation being removed from code snippets
解决方案
This tool removes leading whitespace from each line, which will destroy intentional indentation. If you are cleaning code, use a dedicated code formatter that preserves indentation rather than this whitespace cleaner.
常见问题
Does it remove tab characters?
No. Only consecutive space characters (ASCII 32) are collapsed. Tab characters (ASCII 9) and newline characters are preserved exactly as they are in the input.
Does it remove non-breaking spaces?
No. Non-breaking spaces (Unicode U+00A0, often found in HTML content) are a different character from regular spaces and are not affected. To normalize these, use the Clean Text tool which handles all Unicode whitespace variants.
Will it destroy indentation in code?
Yes — leading spaces on each line are trimmed, which would remove code indentation. This tool is intended for prose text, not source code. For code, use a dedicated formatter that preserves intentional indentation.
Is there a text length limit?
No. Processing runs locally in your browser with no server overhead, so there is no character limit. Large documents with many thousands of words are handled instantly.
Does it preserve paragraph breaks?
Yes. Newline characters separating lines and paragraphs are preserved. Only multiple consecutive spaces within a line are collapsed — the line structure itself is not changed.
Why does my text still have double spaces after processing?
If double spaces persist after processing, they may be non-breaking spaces (U+00A0) rather than regular spaces. Copy the output into a hex editor or use the browser developer console to inspect the character values.
Is my text sent to a server?
No. All processing runs in client-side JavaScript in your browser. Your text is never uploaded, stored, or transmitted to any server or third-party service.
Can it collapse spaces inside HTML tags?
This tool works on plain text, not HTML-aware content. It will collapse spaces inside HTML tag attributes if you paste raw HTML, which may break the markup. For HTML, use an HTML formatter instead.
