I have a workflow that writes output to an Excel file. Every day, it appends a new worksheet with a dynamic sheetname (today's date -1 business day (unless there's a bank holiday involved)). I need to be able to then use this most recent worksheet as input when I run the workflow on the next business day. So I need to dynamically input the most recent file (which I know how to do) and the most recent worksheet (this is where I'm stuck). Especially since I can't really just apply a formula that says "hey grab the worksheet with yesterday's date" since the date might not actually be yesterday. Any suggestions?
