Do you want to get the number of all kinds of filtered content? If there is one, it can be realized by the COUNTIF function.
Assuming that the data is in column A, the operation is as follows:
1. Select the data in column A, use advanced filtering, check "Select non-duplicate records" and confirm.
2. Select the filtered result, copy and paste it into other worksheets (create a new worksheet).
3. Cancel the filtering, and paste the content just copied and pasted into column B (assuming it starts from B 1).
4. Enter =COUNTIF(A:A, B 1) in C 1.
5. Copy down the formula of C 1.
