Need interactive .xlsx on page

I have an .xlsx ROI calculator that I think was made in excel. I need to put it up on my wordpress site so that it’s interactive for visistors to calculate their monthly bill savings. I’ve tried inporting into googe spreadsheet, where it does work live, and linking it to WP with the google spreadsheet inline plugin. It displays on the page but it’s not interactive for users to input data. What’s the best way for a novice accomplish this? I’d even be willing to recreate the calculator within a WP plugin as long as it works.
