underscore is ignored and convert to "-"

[monaye]

After recent update following will replace the underscore "_" to dash "-" of header row.

Excel::load('file.csv', true)->toArray();

Not really an issue, I guess?
This is caused by the Str::slug() function of Laravel.

If you didn't publish the config yet do:

php artisan config:publish maatwebsite/excel

And change the seperator to _

Else add to the app/config/packages/maatwebsite/excel/config.php

/*
    |--------------------------------------------------------------------------
    | Slug seperator
    |--------------------------------------------------------------------------
    |
    | The default seperator for the Str::slug() method.
    | If you have problemen with _ being converted to -, you can
    | change the seperator to _ here.
    |
    */
    'seperator' => '_',
