How to set cell width when export .xlsx files with js-xlsx

Question

I am trying to set a fixed column/cell width to my exported excel files with js-xlsx.

Answer 1

public exportAsExcelFile(json: any[], excelFileName: string): void {

   const header = Object.keys(json[0]); // columns name

   var wscols = [];
   for (var i = 0; i < header.length; i++) {  // columns length added
     wscols.push({ wch: header[i].length + 5 })
   }
   const worksheet: XLSX.WorkSheet = XLSX.utils.json_to_sheet(json);
   worksheet["!cols"] = wscols;
}
