Importing excel cells in wordpress page

I like to import excel cells into a wordpress-page. As I normally do, I select the cells in excel, copy them and them paste them in the wordpress-page. Everything looks good, till I publish it. Only the first row is left, the rest is gone. This is for someone who is no html expert, so exporting the excel sheet to html and then paste it in code is no oppurtunity. I use this method a lot in a mambo site and that works. I hope there is a way to do this easy in wordpress. I don’t want to import a complete worksheet, just some selected cells.
