Hello,
Welcome to Microsoft Q&A!
I got to save data as excel file so I tried to make a reference in uwp project but I couldn't make it.
Currently microsoft.excel
does not work for UWP platform, for this scenario, I'd suggest you submit a feedback/feature request about this API/feature in the Feedback Hub. You could find the Feedback Hub in the Start Menu. Please select Developer Platform->API Feedback as the category when you submit your request. The related team will check the request.
Thank you.
