count data but avoid double entries
Dear all
i have a quite big spreadsheet with 50.000 entries in rows. i want in column A to count the entries but not to count the double entries. There are some data that exist 2 till 10 times. There is any possibility to count the rows in column A but to avoid the double entries? Thanks in advance Manos |
Hi!
Try this: =SUMPRODUCT((A1:A50000<"")/COUNTIF (A1:A50000,A1:A50000&"")) Biff -----Original Message----- Dear all i have a quite big spreadsheet with 50.000 entries in rows. i want in column A to count the entries but not to count the double entries.
