Remove duplicate lines
Paste a list and keep every line only once. The first occurrence stays where it is; later copies are removed.
How it works
-
Paste your text
Type or paste the text in the left box, or open a .txt file. No text to hand? Click Example.
-
Instant result
The result appears as you type. Change the options and see straight away what changes.
-
Copy or download
Copy the result with one click, save it as a file or use it as input for a next step.
Options
- Ignore case:
Appleandapplecount as the same line. Off by default. - Ignore spaces at the start and end:
pearandpearcount as the same (on by default). - Keep empty lines: blank lines are left where they are instead of being treated as duplicates of each other (on by default).
The order of the lines doesn't change. The note says how many duplicates were removed.
To also sort the list, use sort text alphabetically with Remove duplicate lines ticked. To just delete blank lines, use remove empty lines.
