Do you have Multiple Excel Files each containing Multiple Sheets that needs to go through Routine Calculation/Formula Steps? OR
Do you have to manually replace the Excel Files given as Input to Alteryx Workflows?
Then here is an Alteryx Workflow/Macro which will let you import Multiple Excel Workbooks containing multiple Sheets, Apply the required Calculations on each sheet and then Save the Output in same the way as it was provided as Input with same Sheet/Tab Name.
(Note: Output Excel Workbook Name is different to identify Input & Output File easily.)
(Note: Add/Modify the Calculations/Formula in 2nd Macro as per your Data Requirements)
