Assistance with Dax formula for occurrence of character in column

[pbrenneise]

Hi folks,

Is there an efficient Dax formula I can use to count the number of occurences of a particular special character in a column based on conditions? The column looks something like this:

Column A

Bill Murray

John Doe; Joe Biden; Bill Gates

Mark Twain; Paul Bunyan; Jack Black

Stevie Wonder; Erica Karros

Due to the presence of the occasional blank cell, I need ensure that only cells with characters in them are counted, which led me to COUNTA() (not every cell has as a delimiter next to a user's name (e.g. if only one user is listed)). The logic I was considering involved firstly testing to ensure the cell wasn't blank, and then I needed to start counting the number of delimiters in each row with a base count of 1 (again to account for cells with text in them, but do not contain the delimiter in question). Hope that makes sense and appreciate the help, particularly if there's an easier way to do this. I didn't want to unpivot the column and count that way in Power Quert since the table is already too big.

Best,

That helped - appreciate the assistance!

@pbrenneise Try:

Column = LEN([Column A]) - LEN(SUBSTITUTE([Column A],";",""))
