Assignment Text Cleaner

Paste the messy version. Strip smart quotes, double spaces, stray bullets, duplicate lines and tracking links before you paste the text into Word, Excel or an AI prompt.

The short answer

A text cleaner standardises pasted text: it trims lines, collapses repeated spaces and blank lines, straightens curly quotes, removes bullets, URLs or email addresses, deletes duplicate lines and changes casing. This one runs live in the browser, so the text is never uploaded.

Questions about the text cleaner

Is the pasted text uploaded?

No. Every cleanup option runs in JavaScript in your browser. The text, email addresses and URLs are not sent to our server or included in analytics.

Can it remove AI-style punctuation?

Yes. It converts curly quotes and en/em dashes to plain characters, removes ellipsis characters and can strip bullet markers. It does not rewrite wording or bypass AI detectors.

What does “Apply to original” do?

It replaces the original text with the cleaned output and resets the options, so you can run a second pass. Nothing is saved unless you copy or download the result.

Can I clean a CSV or a list of names?

Yes, although the Excel Data Cleaner is better for rows and columns because it understands delimiters and quoted cells. Use this tool for prose, notes and line-based lists.

Does it remove duplicate lines case-insensitively?

Yes. “Assignment” and “assignment” count as duplicates when that option is enabled. Blank lines are kept so paragraph breaks are not lost.

Need it done for you?

Cleaned the text but the data still will not behave?

Text cleanup will not fix numbers stored as text or dates with the wrong locale. Send the workbook and an expert will diagnose the data types and formulas.
