I am trying to export my html table to excel file, using SheetJS library. This is my code:

 var table = document.getElementById("tableToExport");
 var ws = XLSX.utils.table_to_sheet(table, { sheet: "Raport Odorizare",dateNF: 'dd.mm.yyyy'});
 var wb = XLSX.utils.book_new();
 XLSX.utils.book_append_sheet(wb, ws, "Raport Odorizare");
 XLSX.writeFile(wb, "Raport Odorizare.xlsx");

My date in html table look like this: "2021-08-06" (whitout the time)

However when I export to excel my date look like this: "08/06/2021 12:00:24 AM" (see the picture,pls) and I can't figured it out why my date in excel is beeing generated with the time part.
