Remove Duplicate Lines
Remove duplicate lines from pasted lists, keyword exports, copied rows, logs, and draft text while keeping the first occurrence in your browser.
Duplicate line details
No duplicates detected.
Copy the deduped result, then sort lines, join items, count rows, or continue in the Text Cleanup Toolkit.
Remove repeated rows before sorting or importing
Duplicate lines appear in keyword exports, copied spreadsheet columns, merged lists, CMS drafts, logs, QA notes, and pasted research. This tool keeps the first copy of each non-empty line and removes later repeats so the cleaned text stays in its original order.
Example duplicate-line workflow
Start with Trim Lines when pasted rows have uneven edges, use Remove Empty Lines when blank rows inflate the list, then remove duplicates here. If the final order does not matter, finish with Sort Lines Alphabetically; if you need a comma-separated list, continue with Join Text.
Case-sensitive vs. case-insensitive matching
Case-insensitive matching is useful for lists where Alpha, alpha, and ALPHA should count as the same item. Turn on case-sensitive matching when IDs, labels, code-like values, or product names intentionally differ by capitalization.
Privacy and limits
The cleanup happens entirely in the browser session with a practical text-size limit to keep the page responsive. Pasted text is not uploaded to ClearUtils, stored in an account, fetched by a crawler, or sent to a paid API.
