Excel 2003

Hi Steve, Thank you for your post and welcome to the forum, For the purposes of simplicity I am going to assume that the e-mailed spreadsheets you have received are Excel Worksheets. If this is the case you can simply cut/copy and paste them into a new Worksheet.
If however they are not Excel based tables then you should use the Insert>Object operation and follow the steps in the helper.
If you require more help please come back.

regards Pete
