Saving from Excel 2011 to 2013

I have been using Excel 2011 (Mac), but when I try to save or copy worksheets over to Excel 2013 onto my PC the sheet layout changes. Not only do I need to adjust the row height and column widths afterwards, but the zoom level too. All this I find time consuming when I have a number of worksheets.

I understand you can save to an older Excel version, but how do I save from 2011 to the latest 2013.

Thanks
