I'm trying to create a formula to count the occurrences of Barcodes in Sheet2 which is comma-separated in Sheet1, where I'd like to summarize the occurrences.
Sheet1is a product-list. A product can have multiple Barcodes (Column B).Sheet2is a input of Barcodes which occurrences I'd like to count inSheet1.Column CinSheet1is the Count-formula. For the example I've added aCountif()that I used until recently where a product now can have more then one Barcode.
