How to save data from excel file to javaScript array? Excel file is hosted on server.

Question

I have a excel sheet hosted on server called 'abc.xlsx' and url of the file is "https://example.com/abc.xlsx"
I want to show data from a particular cell from excel to webpage.

var database = convertToArray("sheet" , "https://example.com/abc.xlsx");

Here var database is an array.

Actually I want the function "converToArray()"
