I've no idea how many characters can be stored in a single value in a collection. I imagine it's tied to .NET limitations coupled with that Blue Prism is a 32-bit application, so I'd guess it's one of those 'whichever comes first' kind of things. What error message do you receive? And how many characters were in the Excel cell when it failed?
