that would work if he was happy with how the ms charts looked, but if you want them pretty, well... MS ain't pretty. til quark 5, here's what I'd do:
cut text from ms word/excel, then set up new graph at correct size in illustrator, paste in data.
Design the way you want, colors, fonts, etc.
save as, replace data, illustrator will change graph.
Usually works, some bugs with somethings not wanting to change or reverting back to "pre-design" settings.
If they are all text charts (w/columns and such) best bet is to import text into quark, and set up a style sheet with tabs where you need them.
<sbrug> it's alls I got...
