JavaScript: reading an excel-cell value

I am working on a task of automation testing and I need to access an excel file to get the input data.

I need help on how to access specific cell values from a local excel file using Javascript.

I have an excel file in my local storage, which has the word 'After Life' in its cell 'B2'.

Currently, I have made two functions: one for navigation to the desired page and the other for search. But, as I don't know how to import data from a local excel file, I typed the string argument 'After Life' manually for the search function.
