I would be pleased if I could see the name of the import excel files name as progress bar,It would be much better,Each import file has its name displayed during data collection.In this way, the import would be completed by displaying one after the other.
such as the progress bar will be added as a percentage according to the number of files selected to import, the mouse is busy during the import time, this is a busy time. It will have a progress bar attached, is it possible to create such a difficult program, which is not available till date, if you could do it, my hope would be fulfilled, but it is a very difficult task, hope you will try,

Multiple file name and percent
