Quick answer
Use Remove Duplicate Lines when pasted text contains repeated whole lines that should appear only once. Keep the original text, remove duplicates only when each line is an independent item, and review the result before using it in a document, import, or workflow.
Open Remove Duplicate LinesWhen this cleanup is useful
Primary keyword: remove duplicate lines from text. Search intent: clean pasted lists, exported rows, repeated labels, keyword lists, and other line-based text where accidental repeated lines are unwanted.
This article is more practical than the general how-to article. It focuses on pasted text and copied lists where repeated lines often come from exports, manual editing, or combining lists from multiple sources.
Example: pasted text with repeated rows
/about
/contact
/pricing
/contact
/blog
/pricing/about
/contact
/pricing
/blogThis cleanup is safe only if each URL line is an independent item and repeated URLs are not meaningful. If the repeated rows came from analytics events, votes, logs, or records, deduplicating them could change the count or the story the data tells.
Use the right cleanup tool around duplicate-line removal
Use Remove Empty Lines when blank rows are the problem, Sort Text or Alphabetize List only when order can safely change, and Text Cleaner when duplicate lines are only one part of a broader cleanup issue.
Do not use duplicate-line removal to fix repeated words inside sentences. That is a proofreading task for duplicate-word checking, not whole-line deduplication.
Mini decision rule
- Remove duplicate lines only after confirming duplicates are accidental.
- Keep original text before removing lines.
- Review output before importing, publishing, or sending.
- Avoid duplicate removal on ranked lists, logs, votes, data exports, repeated names, or structured records without review.
- Use Text Cleaner when duplicate lines are only one part of a broader cleanup problem.
Common cases
- Pasted text with repeated rows.
- Copied lists with duplicates.
- Repeated names in simple lists.
- Duplicate keywords.
- Repeated labels or categories.
- Exported plain-text items.
- Cleaning simple line-based data.
- Preparing lists for review.
Best practices
- Remove duplicates only when each line is an independent item.
- Preserve order when order matters.
- Do not remove repeated lines that represent real repeated events or records.
- Check output before importing or publishing.
- Avoid pasting private or sensitive data unnecessarily.
- Use the right tool if the issue is duplicate words, empty lines, or spacing instead.

FAQ
What counts as a duplicate line?
A duplicate line is a full line that matches another full line according to the tool’s comparison rules. It is different from a repeated word inside one sentence.
Can I remove duplicate rows from pasted text?
Yes, when each pasted row is an independent line and repeated rows are truly unwanted. Review first if the rows represent real records or events.
Should I remove duplicates from logs or votes?
Usually not without checking the source meaning. Repeated log lines, votes, rankings, events, or records may be meaningful.
Does duplicate-line removal preserve meaning?
Only when the repeated lines are accidental. If duplicates represent counts, repeated names, checklist items, or exported records, removing them can change meaning.
When should I sort text after removing duplicates?
Sort only when the remaining lines are independent and order can safely change. Keep the original order when sequence or ranking matters.
What should I check before using the cleaned text?
Check whether any repeated line represented a real item, record, vote, log entry, or intentional duplicate before publishing, importing, or sharing the result.
