Angular: Unable to access values of non-existent data (reading '0')

I'm encountering an error when trying to import an excel file using the following code

Angular Ag Grid Excel Import

Cannot read properties of undefined (reading '0')

I'm attempting to import a file named Book.csv, and wondering if this type of file can be successfully imported.

1,chocolate,brown,10
2,gum,red,11
3,juice,yellow,5

Upon inspecting the app.component.ts file, it appears that the import is configured for 4 columns.

app.component.ts


    var columns = {
        'A': '',
        'B': 'Make',
        'C': 'Model',
        'D': 'Price'
    };

An issue arises within the App component code at this specific section

 fetchData(info: any) {
    // our information is located in the initial sheet
    var initialSheet = info.SheetNames[0];

The SheetNames attribute is not present in the provided info parameter (=undefined). Verify the data type of the object being passed
