}`

Answer 1

I never create Excel file directly in javascript.

You can send your data to your server and you build your Excel file from it. For example, your have an array of object in JSON, then you parse your JSON and build each sheet based on the objects in the array.

The result of the of the query must be the file generated which enable the user to download it.

It will probably be easier to create your Excel file from Java or C# than in Javascript.
