Count specific phrase (letters and numbers) in continuous range

I am trying to figure out how get a formula that will allow me to count how many times a specific phrase in cell ranges are present.

my problem is, i have cells that contain phrases such as: O2s-1d2a21k

and I am trying to see if I am able to count how many times "1d' is in roughly 200 cells (A1:A200)

Thanks in advance....

=COUNTIF(A1:A200,"*1d*")

That should do it, let me know if you need anything else

Try this:

=COUNTIF(A1:A200,"*1d*")

The * is the wildcard character, which can be used with COUNTIF, so this will match with anything containing "1d".

Hope this helps.
