How to get Laravel Excel data export like this ?

Hello.

I have array like this. I want to change this array so I can export in different format. I want to group the companies distinctly as each row and group dates across top as headings (I have array item for every day in the week). This is array at this moment.

return [
    [
        'company_id' => 1,
        'company_name' => 'ABC Corp',
        'start' => '2021-09-27',
        'end' => '2021-09-27',
        'staff' => [
            [
                'name' => 'Jared',
                'age' => 32
            ],
            [
                'name' => 'Vladimir',
                'age' => 44
            ],            
        ]
    ],
    [
        'company_id' => 1,
        'company_name' => 'ABC Corp',
        'start' => '2021-09-28',
        'end' => '2021-09-28',
        'staff' => [
            [
                'name' => 'Jenifer',
                'age' => 19
            ],
            [
                'name' => 'Woijiec',
                'age' => 30
            ],            
        ]
    ],
    [
        'company_id' => 99,
        'company_name' => 'HBO Inc',
        'start' => '2021-09-27',
        'end' => '2021-09-27',
        'staff' => [
            [
                'name' => 'Pablo',
                'age' => 27
            ],
            [
                'name' => 'Reinir',
                'age' => 40
            ],            
        ]
    ],
    [
        'company_id' => 99,
        'company_name' => 'HBO Inc',
        'start' => '2021-09-28',
        'end' => '2021-09-28',
        'staff' => [
            [
                'name' => 'Anjun',
                'age' => 30
            ],
            [
                'name' => 'David',
                'age' => 28
            ],            
        ]
    ],
]
