I have all of my 38 years worth of research from the archives and publications archives on an excel spreadsheet I am looking for someone you can tell me how to load it here on research gate.
I guess you want to add all the items from your excel file as separate entries in ResearchGate (automatically export data for multiple items). AFAIK there's no official way to do this (but you should contact the RG team to be sure).
Some "quick and dirty" could be to add a single RG entry entitled e.g. "List of my achievements" which can be the excel list exported to pdf.
