Text Formatter

Clean up messy text in one pass: collapse double spaces, trim blank lines, and convert full-width characters to plain half-width — then copy the tidy result. No upload, no sign-up — your text never leaves your browser.

What is the Text Formatter?

The Text Formatter cleans up messy text in a single pass. It collapses runs of double and triple spaces down to one, trims whitespace from the start and end of every line, removes the extra blank rows that pile up when you copy and paste, and — uniquely among most English-language cleaners — converts full-width characters (the wide ＡＢＣ１２３ produced by CJK input methods) into ordinary half-width ASCII. When text arrives ragged from a copy-paste, a spreadsheet export, a chat log, or a bilingual document, this tool makes it tidy and ready to use, then lets you copy it with one tap.

The text formatter normalizes everything in your browser, so even sensitive documents stay on your device. Nothing is uploaded, logged, or saved — the cleanup runs locally as you type, and closing the tab leaves no trace. That matters when the text you are tidying is a draft contract, an internal note, or anything you would rather not paste into a stranger's server.

How to use it

Paste the messy text into the top box.
Tick the cleanup actions you need — collapse spaces, trim lines, remove blank lines, or convert character width.
Read the cleaned text in the lower box; it updates the instant you type or change an option.
Click Copy to take the tidy version with you, then close the tab. The whole flow is paste, clean, copy, leave.

The method behind it

Each action is a precise, transparent operation that runs locally and never reorders or rewrites your words — it only touches spacing and character width:

Collapse extra spaces — any sequence of two or more spaces or tabs becomes a single space; line breaks are left alone.
Trim each line — whitespace at the beginning and end of every line is removed, fixing accidental indentation from copy-paste.
Remove blank lines — three or more consecutive newlines (two or more empty rows) collapse to a single blank line, keeping one clean separator between paragraphs while dropping the rest, plus any blank lines at the very top or bottom.
Full-width → half-width — characters in the Unicode full-width block (U+FF01–U+FF5E) map back to their ASCII equivalents, and the ideographic space (U+3000) becomes a normal space.
Half-width → full-width — the inverse mapping, for the rarer case where you need wide forms to fit a CJK layout.

Examples

Input "Hello world" (multiple spaces) → "Hello world".
Input "Ｈｅｌｌｏ１２３" (full-width) → "Hello123" (half-width).
A block with three blank rows between paragraphs is reduced to a single blank row between paragraphs.

Common use cases

Cleaning text pasted from PDFs, spreadsheets, or chat that has irregular spacing.
Converting full-width letters and numbers from Chinese, Japanese, or Korean documents to plain ASCII for forms, code, or databases.
Tidying writing before submitting it somewhere that formatting matters.
Preparing copy for a CMS or email where stray whitespace would show up in the published result.

Why use this one

Most text cleaners stop at trimming spaces. This one adds full-width to half-width normalization that Western tools usually skip, bundles several cleanup actions so a single paste does the whole job, and gives you one-click copy — all in the browser with no account and no upload. It loads instantly on mobile and the cleaned text appears live, with no button to press to see the result.

It is part of a small, focused text toolkit, and each tool has a clear job. If your real problem is wrapped lines that need to become one continuous paragraph, Remove Line Breaks is built for exactly that — this formatter deliberately leaves your line structure intact and only normalizes spaces and character width, so the two never overlap. To change capitalization, use the Case Converter; to check the final length of your cleaned text, the Word Counter gives live word and character counts.

Frequently asked questions

What does full-width to half-width conversion do?

Full-width characters (such as ABC123, common when typing with a CJK input method) take up the space of a wide character. Converting them to half-width turns them into ordinary ASCII letters, digits, and punctuation (ABC123). This is useful when pasting text from Chinese, Japanese, or Korean documents into systems that expect plain ASCII.

How does it clean up extra spaces?

The formatter collapses any run of multiple spaces into a single space and removes spaces at the start and end of lines. This fixes text that has uneven spacing from copy-pasting or manual alignment, without disturbing the words themselves.

Will the text formatter remove my paragraph breaks?

It can trim extra blank lines so you do not have several empty rows in a row, while keeping a single blank line between paragraphs. If your goal is to join wrapped lines into one continuous paragraph, the Remove Line Breaks tool is the better fit.

Is my text private when I format it here?

Yes. Every cleanup action runs locally in your browser, so the text you paste is never sent to a server and nothing is stored.
