Need help with VBA code

Question

I have many folders. Each folder contains an excel spreadsheet file. Path is as follows:

"C:\DU1212\DU1212.xls"

Folder are named as DU1212 only the numer 1212 changes for every folder.

Excel files names inside these folders are named similarly such as DU 1212.xls.

I have dozens of these files generated everyday.

I would like to use VBA code to convert each excel file to csv files. This is all I need.

Can someone help me as I am not very good at coding and do not consider myself a programmer.
Thank you in advance.
