Upgrading a Excel and a Word file to Office 2010 and Make it work properly

The mandate is to convert an Excel file containing some macros and a Word file that is taking data and charts from this Excel to a Microsoft Office 2010 compatible one. Since both files were created under Office 2003, there are some designs and look and feel issues which would need to be repaired. As you will see when comparing the 2 PDF attached, when producing the files from the Word document with Office 2012 the results is not good in terms of graphic display. The lines are fat and we cannot read well the wording behind. Basically, a revision of the Excel file containing some macros as well as a word document that is taking the references form the Excel file for producing the chart of the PDF should be done to make it compatible and looking good with Microsoft Office 2010. thanks for your help.
