How to use Remove Duplicate Lines
- Paste the listPut one item per line in the left box. The sorted result appears on the right at once.
- Pick the optionsChoose how to sort and tick Remove duplicates or Reverse the order if you need them.
- Copy the resultCopy it, download it as a text file, or click Use as input to apply another step.
Paste a list of emails, keywords, names or codes and every line that appears more than once is cut down to its first appearance, in the original order, with the number of duplicates removed shown beside the result. Stray spaces at either end are ignored, and so is case if you tick it, so that Apple and apple count as one. Sort the result too if you want it in order.
How it works
Remove Duplicate Lines is a web page that does its work on your own device. Everything you type or choose is worked out by your browser and never sent to a server, so nothing is stored and there is nothing to delete. There is no account, no sign-up and no limit on how often you use it.
Cleaning a mailing list
Paste the column of email addresses, tick Ignore upper and lower case, since addresses are not case sensitive in practice, and copy the result back.
Questions
Which copy of a duplicate is kept?
The first one. Later repeats are removed, so the list keeps the order in which items first appeared.
