I searched and found a solution that almost made my day :)
The problem I have is that some strings that I want to create checksums on are more than 255 characters and than I get a #VALUE returned.
I want to create a checksum for each row in my sheet, so I have a formula similar to this: =md5hash(concatenate(C4;D4
Thankful for all help.
Now attached a file for your reference:
