Paste your text, turn on the Remove Duplicates option, and click Run to keep only the first copy of each matching line. This is the fastest way to clean repeated rows from exports, notes, contact lists, keyword lists, and copied blocks from spreadsheets or web pages.
Duplicate line cleanup is useful when you are reviewing email lists, tag exports, inventory rows, log snippets, copied notes, AI-generated lists, or any column of text where repeated entries make the result harder to scan. It is especially helpful before importing text into a CMS, comparing data manually, or turning a messy list into something you can sort or reformat.
This tool removes exact matching lines after the other selected cleanup steps run. That means you can first remove extra spaces, bullets, or leading tabs, then dedupe the cleaned result. If two lines still differ after cleanup, both lines stay. That behavior is useful when you need predictable results instead of fuzzy matching.
A common workflow is: remove bullets from a copied outline, remove extra spaces from the lines, then remove duplicates and sort the final list. Another common workflow is pasting email addresses or product IDs from multiple sources, deduping the list, and then exporting it as a comma list or semicolon list for reuse.
This example shows repeated lines from a copied list being reduced to unique entries. It is the kind of cleanup people use before importing values into a spreadsheet, CRM, ad platform, CMS, or prompt.

Duplicate line removal also helps when copied notes or exports repeat the same value several times. After deduping, the list is easier to review, sort, and share.

Paste one line per item, turn on Remove Duplicates, and click Run. If the text also has messy spacing or bullets, clean those first so duplicate lines match correctly.
It works well for copied text from spreadsheets, PDFs, websites, documents, email exports, inventory rows, notes, AI-generated lists, and contact data.
Yes. The tool runs in the browser so you can clean text quickly without installing extra software.
Yes. The tool keeps one copy of each exact line after the selected cleanup steps have been applied. It does not guess at similar lines or merge partial matches.
