Duplicate Line Remover
Remove repeated lines from a block of text, keeping the first occurrence of each.
- Original lines
- Unique lines
- Duplicates removed
Worked example
The lines Apple, Banana, Apple, Cherry, Banana become Apple, Banana, Cherry. The first time each line appears is kept, in its original order.
How this works
Lines are compared exactly. Capital letters count, so "Apple" and "apple" are different lines, and spaces count, so "text" and " text" with a leading space are different lines too. Lines are never trimmed or changed before they are compared. If you want that, use the Whitespace Cleaner first. A blank line is still a line, so the first blank line is kept and later blank lines are removed like any other repeat.
The lines that are left stay in their original order and are never sorted. Their line breaks stay as they were, so text with Windows line endings comes back with Windows line endings. To put lines in order, use the Text Sorter.
What this result means
The result is your text with repeated lines removed, keeping the first time each line appears.
