Frequently asked questions
Is the order preserved?
Yes. The first occurrence of every line is kept in its original position. Only later duplicates are removed.
Can I match case-insensitively?
Yes. Untick 'Case-sensitive comparison' and 'Email@x.com' and 'email@x.com' count as the same line.
What about lines with extra spaces?
Enable 'Trim each line before comparing' and lines that only differ in surrounding whitespace are treated as duplicates.
How many lines can I dedupe?
Up to 2 MB of text per job, comfortably hundreds of thousands of lines.
