How to convert (row, col) to 'B2'?

[gigcasters-dev]

I am looking at the borders of specific cells. How do I convert a (row, col) to a cell address?

var workbook = XLSX.readFile("./source.xlsx", {cellStyles:true});
var first_worksheet = workbook.Sheets[workbook.SheetNames[0]]; // First Page of xlsx
var address_of_cell = 'B2';
var desired_cell = first_worksheet[address_of_cell];
console.log(desired_cell.s.border);

I ended up doing:

xlsxLoc = ((String.fromCharCode((97 + col)).toUpperCase()) + (row + 1));
