phpoffice/phpspreadsheet is a successor of phpExcel. We recently developed an automated solution to pull all the backup success rate reports from Dell EMC Data Protection Advisor (DPA). The portal which displays the report was good but not enough to use that information further like sharing the reports, pivoting etc..
After trying several methods, found this library to be very useful. There aren’t many examples available on the internet to retrieve data from MySQL and write to XLSX file. Hope this blog might be helpful who would like to use this library for creating XLSX files. Fear not, it doesn’t throw errors while opening this file in MS Office Excel
