Here is the picture. To large to post it up.

I think also Excel don't show every cell to if you look closley. It's space.

I want to scroll and drag with the mouse, you know what im sayin?
exchange.xlsx
Here is the file i use. Its EUR/USD Currency.

Edit: The spaces is not in the file.
The file only writes
