the text.xlsx is on my GitHub repo for this project.
if you look at my index.php, you will see the following
$excel=basename($conf, '.ini') . ".xlsx";
if (! $e->set_excel($excel, 'false'))
$error='<div class="alert alert-danger">ERROR: file is not configured or not found for: '.$excel.'</div>';
make $excel match your file, I had a configuration file for displaying select Excel cells called test.ini.
Try downloading a zip from my GitHub repo for this project, if you still get errors please let me know; I am slowly working on updating this project when I get free time.
