Answer 1

The PHPExcel_IOFactory class file is in the phpoffice/phpexcel package, which is a dependency of the yii2-phpexcel extension. Please make sure that you have successfully installed the extension. You could take a look at the vendor directory, and check if there is a following structure:
...
moonlandsoft/
...
phpoffice/
phpexcel/
Classes/
PHPExcel/
IOFactory.php
...
If not, you could reinstall the yii2-phpexcel extension.
In order to answer your question, I installed the extension on my application, and put the following snippet in an action:
$fileName = '/tmp/a.xls';
$data = \moonland\phpexcel\Excel::import($fileName);
print_r($data);
The $data was printed correctly. Then, I renamed the phpexcel directory in vendor/phpoffice to phpexcel2. This time, I reproduced your error message:
