How to Remove Duplicate Lines from a List (No Excel)
Clean a list of emails, keywords or URLs by removing repeated lines. Ignore case, trim spaces, drop empty lines and sort, all in your browser.
Quick answer: open Remove Duplicate Lines, paste your list (one item per line) and copy the result. The first copy of each line is kept and the repeats are removed.
Step by step
- Open the duplicate line remover.
- Paste your list, one item per line.
- Choose options: ignore upper/lower case, trim spaces, remove empty lines and sort A to Z.
- The tool shows how many lines were kept and removed. Tap Copy.
Which option should I use?
| Situation | Option |
|---|---|
Email list where Ali@x.com and ali@x.com are the same person |
Ignore case |
| Lines copied from a sheet with stray spaces | Trim spaces |
| A list with blank gaps | Remove empty lines |
| You want an alphabetical list | Sort A to Z |
Good uses
- Cleaning a keyword list before a search campaign.
- Merging two lists of URLs or usernames.
- Tidying hashtag lists. Make them with the Hashtag Generator first.
Is my list private?
Yes. It is processed in your browser and nothing is uploaded. Large lists work, limited only by your device.
