Whitespace Cleaner

About this tool

The Whitespace Cleaner tidies text that has picked up extra spaces, tabs or blank lines. Paste or type into the Input box and the Output box updates on every keystroke — there is no Clean button to press. It collapses every run of spaces and tabs into a single space, removes the leading whitespace from each line, and reduces a run of two or more blank lines to one. Whitespace at the very start and end of the text is trimmed as well.

There are no toggles, checkboxes or settings. The cleaner applies all of its rules automatically, so the only controls are Copy, which copies the cleaned output, and Clear, which empties both boxes. It also reports how many characters were removed and how many lines were collapsed, which gives you a quick sense of how much invisible clutter was in the original.

Writers use it to even out spacing in drafts, developers use it to flatten copied code or config snippets, and data entry teams use it to clean lists and fields before importing them into a spreadsheet or database. It is equally useful for text copied from PDFs, emails, web pages and word processors, where hidden tabs and stray blank lines are common.

Everything runs locally in your browser. The text you paste is never uploaded, stored or sent to a server, so it is safe to use with internal notes, unpublished drafts and other private content. There is no signup and no file upload — just paste, copy and go. If the cleaned text is JSON, paste it into the JSON Formatter & Validator to confirm the structure is still valid. Placeholder copy from the Lorem Ipsum Generator often arrives with stray line breaks and doubled spaces, so run it through here before dropping it into a mockup.

How to use

1. 1Paste or type your text into the Input box. Cleaning starts as soon as you type.
2. 2Check the read-only Output box, which updates automatically with the cleaned text.
3. 3Use the Chars Removed and Lines Collapsed counters to see how much was cleaned.
4. 4Click Copy to put the cleaned text on your clipboard.
5. 5Click Clear to empty both boxes and start again.

The quick brown fox
jumps over the lazy dog

Second paragraph with extra spaces.

The leading tab and extra blank lines are removed, and each run of spaces becomes one space.

What counts as whitespace

Common uses

• Cleaning text copied from PDFs, emails or web pages before pasting it into a CMS or document.
• Preparing plain-text lists and fields for spreadsheet or database imports where extra spaces cause mismatches.
• Tidying copied code or config snippets where tabs and repeated spaces have made lines uneven — leading indentation is removed, so keep a copy if you need it.
• Fixing uneven spacing in articles, email drafts and other documents.
