Clean up lists fast
Mailing lists, keyword lists, product codes or name lists often contain duplicates and blank lines. Instead of cleaning them up in a spreadsheet, you can do it here in seconds.
Sorting is natural: “file 2” comes before “file 10”, and accented letters are sorted correctly.
Frequently asked questions
Is the order kept when removing duplicates?
Yes. The first occurrence of each line is kept and the rest of the order stays the same.
Can I ignore upper and lower case?
Yes. With “Ignore case”, “Apple” and “apple” count as duplicates.
How many lines can it handle?
Even lists with a hundred thousand lines are processed in a fraction of a second, right in your browser.
