Remove duplicate lines
What does Remove Duplicate Lines do?
This tool cleans keyword, tag, URL, lead and other one-item-per-line lists. It compares complete line text, keeps the first occurrence only, and leaves the result in predictable original order for easy auditing.
Deduplication rules
CRLF and CR line endings are normalized to LF, then a set tracks each complete line. Later identical lines are removed; case, leading or trailing whitespace and different characters remain distinct items.
List example
For apple, apple, banana, apple, the output is apple and banana. apple stays in the position of its first occurrence, without silently rewriting case or text.
How to use
- Paste one item per line.
- Remove duplicates while retaining first-occurrence order.
- Review and copy the result into your sheet or content system.
Frequently asked questions
Does it ignore letter case?
No. Apple and apple are distinct complete lines, so the tool does not change your data meaning without permission.
Does it trim spaces inside lines?
No. It only removes repeated lines and preserves the first line exactly. Clean whitespace separately when that is your intent.
Will it reorder the list?
No. Every unique line remains in first-occurrence order, which makes the result easy to trace back to the source.
