Faster way to check and sort duplicate numbers
I have been using COUNTIF(A:A,A#) to check for doubles for a while now. The
formula works fine for small ranges of numbers, but really starts to lag after 4000 numbers or more. Well, now I am having to deal with serial number ranges of 10-60000 and my formula is no longer practical. Is there a faster way to identify multiple (up to 5 or so) occurences of the same number(with alpha characters) in a column? Thanks, |

Faster way to check and sort duplicate numbers
I tried the pivot table, but I have too many unique values. I read that the
pivot table can only hold about 8000, and I'm way past that. It does work for my smaller ranges, though, quite well.
