How to use the remove duplicate lines
- Paste your list, one item per line.
- Choose whether case and extra spaces matter.
- Copy the cleaned list.
What counts as a duplicate
By default “Red” and “red” are treated as the same line, and spaces at the start or end are ignored. Tick Case-sensitive to keep different capitalisations, or untick the spaces option to treat “ green” and “green” as different.
Examples
red, blue, green (3 removed with spaces ignored)
a, A
