Describe your issue

I have been using the (new ObjectImport)->toArray($path) function in order to import multiple sheets but with some files it just returns null.

I have included two files in the attachment, one(0001104659-16-155721.xlsx) returns null in an array of array, the other returns the correct result of array[96].

How can the issue be reproduced?

You can find the excel files in the attachment.

0001104659-16-155721.xlsx
0001104659-17-065845.xlsx

1. Create an Import class

<?php

namespace App\Imports;

use Maatwebsite\Excel\Concerns\Importable;
use Maatwebsite\Excel\Concerns\ToArray;

class FilingsImport implements ToArray
{
    use Importable;

    public function array(array $array)
    {
        // TODO: Implement array() method.
    }
}

2. Use this import class in another class(in my case it's in a job):

$allSheets = (new FilingsImport)->toArray($this->path);

This is the return I got with a valid excel file(0001104659-16-155721.xlsx):

array (
  0 => 
  array (
    0 => 
    array (
      0 => NULL,
    ),
  ),
)

Yet another valid excel file(0001104659-17-065845.xlsx) returns the correct result of array[96].

What should be the expected behaviour?

Expected behavior should be that it returns the correct result of array of 108 since there is 108 sheets in the file.
