I am trying to set columns name using the Xlsx npm package, after that, I want to map the excel file to get the value of the cells, I want to do something like the below code. is it something similar possible with the xlsx or any package, I have tried the convert-excel-to-json npm, the problem is with this package is sometimes the cell will be empty so I want to get the empty cell too, on this package it is skipping the empty cell.

// Mapping columns to keys
        columnToKey: {
          A: "roll",
          B: "name",
          C: "English",
          D: "Math", } 

  const mapExcel = excelData.sheetName.map((student) => {
       const {
         roll,
         name,
         English, Math } = student }
