'Is There Any Means of Exporting an HTML Form to an Excel File Offline?

So I am admittedly fairly new to programming but I'm looking at helping some of my employees with some surveying information as well as eliminating paper waste. With Javascript, I have been able to create a new Excel file with each passing entry but I have not found a means of adding the information to an existing spreadsheet. I'm more than willing to utilize an HTML table instead of exporting into an excel file, I can handle that side of it all manually. That said, I'm having trouble having the form write to an HTML table without taking it online too. Again, I am not well-informed on coding and am in the early stages of learning everything beyond HTML but I feel like this has to be possible, right?

Any time I submit a file it exports to an entirely new excel spreadsheet instead of adding to an existing one.
