Use Table and Cell styles....
Ok, can yo be a little bit more specific?
Since i don't whant the text to be in any cells or tables i placed it as an "Unformatted tabbed text" is it some way i can edit this text but still keep the edits when i update the link?
No. For this situation you would need to do the formatting in Excel, or don't link and use Copy/Paste Without Formatting to update manually.
