excel date format in php
Please use this formula to change from Excel date to Unix date, then you can
use "gmdate" to get the real date in PHP:
UNIX_DATE = (EXCEL_DATE - 25569) * 86400
and to convert from Unix date to Excel date, use this formula:
EXCEL_DATE = 25569 + (UNIX_DATE / 86400)
After putting this formula into a variable, you can get the real date in PHP
using this example:
$UNIX_DATE = ($EXCEL_DATE - 25569) * 86400;
echo gmdate("d-m-Y H:i:s", $UNIX_DATE);how do i use php read excel file
Mark Baker was extremely helpful in guiding me to the right answer. I don't use Composer with PHP (I should probably learn), but given that, in order to get this to work I went to the GitHub page for PHPExcel (https://github.com/PHPOffice/PHPExcel), clicked the green Clone and download button, and then the Download ZIP link.
After unzipping the file, I got a folder called PHPExcel-1.8. I moved that folder to the same folder as both the Excel file I wanted to read (in my code below test.xlsx) and the PHP file that has the code below.
The key to getting it to work was inputting the correct path to the IOFactory.php file. It may seem simple to some, but it was tripping me up.Copyright © 2021 Codeinu
