Optimized whole code, added redim step var.
I had to create Excel files for my needs, but I wondered how to do it because xlsx files are not raw editable; so I searched for a way do it.
Excel can open multiple files type, and the XML is a good way to do it so here it is.
It creates an Excel XML file, with which you will be able to :
-Create Cells and set it's color
-Set column width
-Set global text horizontal align
-Set XML author
