I have an Excel file with several fields, including a date type field. I am using PhpSpreadSheet to read the Excel cells and load them in a query but I realized that when reading the cell that contains a date, it reads it as a number, for example in the excel I have 06/01/2018 and php lo returns as 43106. Any idea how to read as such on 06/01/2018 or how to convert the whole number?
