Do not run Composer as root/super user! See https://getcomposer.org/root for details

  Problem 1
    - phpoffice/phpspreadsheet[1.17.0, ..., 1.17.1] require ext-fileinfo * -> it is missing from your system. Install or enable PHP's fileinfo extension.
    - Root composer.json requires phpoffice/phpspreadsheet ^1.17 -> satisfiable by phpoffice/phpspreadsheet[1.17.0, 1.17.1].

To enable extensions, verify that they are enabled in your .ini files:
    - /www/server/php/74/etc/php.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Installation failed, deleting ./composer.json.
