Click export at the top and save as a length delimited CSV file then open in excel put your headings in sort everything out then away you go, is the way I would do it.
Yoou could try sending to Excel through office integration but mine seems to of stopped working so I dont know if it works.
I agree with Rhianrach, save as a csv file. This is the way I have always done it, I have used quite a few different sage versions and it hasn't failed yet.
