How to use Remove Extra Spaces
The Remove Extra Spaces tool cleans up messy whitespace in any block of text entirely in your browser — nothing is uploaded. It collapses runs of multiple spaces down to a single space, trims leading and trailing whitespace from every line, and optionally strips blank lines and tabs. Writers, developers and data-entry teams use it to tidy copy-pasted text, normalise log output, and prepare clean input for parsers that choke on irregular spacing.
- Paste or type the text you want to clean into the input area.
- Toggle "Remove blank lines" to collapse consecutive empty lines into none.
- Toggle "Remove tabs" to replace tab characters with spaces before collapsing.
- The cleaned output updates instantly — review it in the output area.
- Click Copy or use the result actions bar to copy the cleaned text to your clipboard.

Why extra spaces cause problems
Extra whitespace is one of the most common formatting issues in digital text. Copy-pasting from PDFs, emails, or word processors frequently introduces doubled or tripled spaces that are invisible to the author but cause real problems downstream. Code parsers may misinterpret indentation, CSV importers can create phantom columns, and search engines treat "hello world" and "hello world" as different strings. In HTML, browsers collapse multiple spaces visually, but the raw source stays bloated — increasing file size and making diffs noisy. A single normalisation pass solves all of these issues.
Whitespace characters and Unicode
The term "whitespace" covers more than just the ASCII space (U+0020). Common whitespace characters include the horizontal tab (U+0009), line feed (U+000A), carriage return (U+000D), non-breaking space (U+00A0), and several Unicode spaces like the em space (U+2003) and thin space (U+2009). This tool targets the most common culprits — repeated ASCII spaces and tabs — which account for the vast majority of formatting problems in everyday text. For specialised Unicode normalisation, a dedicated tool or regex replacement is recommended.
| Character | Unicode | Description |
|---|---|---|
| Space | U+0020 | Standard ASCII space — the most common whitespace |
| Tab | U+0009 | Horizontal tab, typically 4 or 8 spaces wide |
| Line feed | U+000A | Unix-style newline |
| Carriage return | U+000D | Part of Windows-style CRLF line ending |
| Non-breaking space | U+00A0 | Prevents line break; common in HTML |
| Em space | U+2003 | Typographic space equal to the current font size |
Worked examples
Collapse spaces
Inputs: 'a b'
Result: 'a b'
Trim line ends
Inputs: lines with trailing spaces
Result: leading/trailing spaces removed per line
Remove blank lines
Inputs: double-spaced prose
Result: single-spaced output
Glossary
- Whitespace
- Any character that represents blank horizontal or vertical space — spaces, tabs, newlines, and Unicode space characters.
- Trim
- Removing leading and trailing whitespace from a string or line so only the content characters remain.
- Collapse
- Replacing a run of consecutive identical characters (e.g. multiple spaces) with a single instance.
- Blank line
- A line containing only whitespace characters or nothing at all, often produced by double line breaks in copy-pasted text.

Frequently Asked Questions
Why use Remove Extra Spaces?
- Collapses multiple consecutive spaces into one in a single pass without altering any letter content
- Per-line trimming removes leading and trailing spaces that cause CSV parsers to create phantom columns
- Tab-replacement converts tab characters to spaces before collapsing for fully consistent output
- Blank-line removal compresses double-spaced prose into tight single-spaced output in one step
Common use cases
- Clean up text pasted from a PDF where the extractor inserted an extra space between every word
- Normalise a CSV export where leading spaces in column values break downstream string comparisons
- Tidy double-spaced prose pasted from a word processor before inserting it into a web CMS
- Remove irregular spacing from a copied code snippet before reformatting it with an auto-linter
- Strip trailing spaces from each line of a config file before committing it to version control
