Combine several Excel sheets in one Word doc?

Hi, All you have to do is open a word file and link the worksheet you want in the document.
If you set the update to manual you will have to refresh the data manually (check you word help file) or you can set it to automatic.
You may link as many as you want, keep in mind that the process slows down if there are network shares involved.

It really depends on what you mean by "and make them work together". There is no straightforward way to embed an Excel workbook in a Word document such that you can edit it and have the edits reflected in any other workbook embedded in the document. For that kind of thing it's much simpler to maintain a single external workbook and have the relevant parts linked to the Word document.
