How to parse xls file in JavaScript to json or xml?

Question

JavaScript

Greetings!
There is a task in the input to load the xls file and then parse it line by line. I read similar questions, but it did not lead to anything.
I tried to make SheetJs this library , but as far as I understand, it is necessary to run the whole thing in node js, and the examples are not very clear.
