Remove Duplicate Lines
Paste a list of lines below to instantly remove duplicates, keeping only the first occurrence of each line.
How to use the remove Duplicate Lines
- Paste your list, one item per line, into the input box.
- Choose whether matching should be case-sensitive and whether to ignore extra spaces.
- Click 'Remove duplicates'.
- Review the cleaned list and copy the result.
Example
Given the list apple, banana, apple, cherry (one per line), the tool returns apple, banana, cherry — removing the second, repeated "apple" line while keeping the first occurrence.
Why remove duplicate lines?
Lists exported from spreadsheets, email tools, or scraped data often contain repeated entries. Removing duplicates manually in a long list is tedious and easy to get wrong — this tool does it instantly while preserving the original order.
Keeps the first occurrence
Rather than sorting or reordering your list, the tool keeps each unique line in its original position, only removing later repeats — so your list structure stays intact.
