But, but… you haven’t shown a process block in the pic!
Here is what I assume you want to do: Read the excel formulas from an excel sheet and store them in queue items, so you can use the formula in the process later by accessing QueueItem.SpecificContent.
Take a look at this sample. I won’t send .xaml, please practice this yourself 
Edit: RowNumber should probably be RowIndex + 2 (not +1) unless you don’t have headers. So RowIndex 0 is corresponding with ExcelRow 2.
Happy automating
