Another faster way to do this:
This step only needs to be done once: In Excel add the Camera tool to the toolbar (Tools > Customize > Toolbar, then select Commands tab, on the left, choose Tools, then on right scroll to bottom and choose "camera" and drag it onto the toolbar wherever you want. Click OK).
In Excel, select the range of cells, and click the camera button on the toolbar, and click in Excel (it will place a picture there - if you skip this step, it will not retain the formatting). Then go to Pages and paste. You will get the image exactly as it is in Excel.
