Hi there!

To count the cells in a range that have alphanumeric data, you can use the COUNTIF function in Excel. Here's how:

1. Select the range of cells that you want to count.
2. In the formula bar, type "=COUNTIF(range,"*#*")" (without the quotes), where "range" is the range of cells you selected in step 1.
3. Press Enter.

The COUNTIF function will count all cells in the range that contain at least one number. The asterisks before and after the "#" symbol are wildcards that allow the function to count cells with any number of characters before or after the number.

For example, if you have the following data in cells A1:A8:

asd
we
rty
22r
45aa
1s
wer
tyu

And you want to count all cells that have at least one number, you would select cells A1:A8 and enter the formula "=COUNTIF(A1:A8,"*#*")". The result would be 3, since there are three cells in the range that contain at least one number (22r, 45aa, and 1s).
