Hi
Hope the below steps would help you resolve this
—use a excel application scope and pass the filepath as input and from that activity get the output with a variable of type Workbook named Out_workbook
—then use a assign activity like this to get the sheet names
Arr_sheetnames = out_workbook.GetSheets.ToArray()
Arr_sheetnames is a variable of type Array of string
Or
You can try with custom activities
