The amr-users-plus export to excel feature uses the phpoffice/phpspreadsheet library. The library must be accessible on the server. Here are two ways to make it available:
Option 1: the easy low tech way: use the plugin cbxphpspreadsheet
Add the plugin https://github.com/codeboxrcodehub/cbxphpspreadsheet to your wordpress installation. The plugin does not need to be active, it.only needs to exist in your wordpress plugins folder. It may be safer to activate the plugin so that you don’t accidental delete it thinking it is not in use.
The amr-users-plus plugin will check for it’s code and load the necessary files if the files are found. Then in the plugin list settings, simple tick the checkbox to show the ‘export to xls’ option in the lists you want.
Option 2: use composer to load the spreadsheet.

The amr-users-plus XLS export feature will not function if phpspreadsheet and the writer class are not found. It will give you an error message instead.
