@yazanhijazeen32 startCol has to be a number [0 for A, 1 for B and so on…)
Also you might need to provide a sheetName.

kindly show the Warning message in the snap and it seems that u have not provided the sheet name so it may be the problem

usually, it is “Sheet1” for a new excel file
or change the sheet name as in the exporting excel file

try this out
