Excel Data to Populate Word Template

We have an Excel Spreadsheet containing data. I need this data to then populate a word template (not a new word document) but a specifically designed word template. I have the spreadsheet already prepared. I will need a word document creating with the relevant bookmarks for the data to come across and then I will design the prospectus once the technical side as been done. I envisage this being done through a Macro, with a button embedded in Excel which will then open and populate the word document. I have attached the excel document and under the tab prospectus I have highlighted the information in red which needs to be brought across into the word template.
