In which case should we read the multiple file using regression in Excel Input step?

I am reading the two file( customer.xlsx and employee.xlsx) using regression in excel input step. As the number of field differ in both file, the output is looking like (see snapshot)

Can you give the example of such case where we need to read the multiple files using regression in excel input step?
What I am thinking if all file are having same field then it is useful…

Hi Shubham,

-Use Get File Names plugin to get all files for execution.
-Create workflow for file operation.
-Drag workflow executor plugin next to get file names plugin and call above workflow in workflow executor plugin.
