I’m using XLSX package to read an excel file and for some reason some Date Objects are Date and others are string.

I’m using this line to define cells as Date type.

const workbook = XLSX.read(buff, {cellDates: true, dateNF:"dd/mm/yy"});

When is time to read this date “26/07/2024 00:00:00” I get undefined in this sentence

const dateToParse = new Date(dato);
