Spreadsheet/Excel

Framelix have integrated  PhpSpreadsheet, a tool to generate spreadsheet files (for Excel, OpenOffice, etc...)

We have a small wrapper around it, for most common features. Framelix/src/Utils/SpreadsheetWrapper.php

A basic spreadsheet file out of a PHP array. Notice that the timestamp in the data is UTC, as all times are default UTC, except times displayed in the frontend with the proper HTML Tag (which are user device based).
