Duplicate Line Finder
Find repeated lines in a long list and see how many times each one appears — useful for cleaning lists, order IDs or logs.
How to use
- Paste one item per line; duplicates are listed with their counts
- Blank lines are ignored and matching is exact, including case
FAQ
Does it ignore case?
No — comparison is exact, so Apple and apple count as different entries. Lowercase the text first if you need a case-insensitive check.
Why doesn't it merge the duplicates?
This tool only reports them. Use the text dedupe tool afterwards to remove the repeated lines.
