Using the Larvel 6.0 with the following code for exporting into Excel. the exported file is shown corrupted.

However, when we have checked same code in Laravel 7 and above versions, the file is getting exported and showing correctly.

We are using the following code

public function excel()
        {
            $report = new Report;
            $report->run()->exportToExcel('excel')->toBrowser("myreport.xlsx");
        }

<?php

namespace App\Reports;
use \koolreport\KoolReport;

class Report extends \koolreport\KoolReport
{
    use \koolreport\laravel\Friendship;
    use \koolreport\export\Exportable;
    use \koolreport\excel\ExcelExportable;

    function settings()
    {
        return array(
            "dataSources"=>array(
                "sample_data"=>array(
                    "class"=>'\koolreport\datasources\ArrayDataSource',
                    "dataFormat"=>"table",
                    "data"=>array(
                        array("name","age","income"),
                        array("John",26,50000),
                        array("Marry",29,60000),
                        array("Peter",34,100000),
                        array("Donald",28,80000),
                    )
                )
            )
        );
    }
    function setup()
    {
        $node = $this->src('sample_data')->pipe($this->dataStore('unloadsPivot'));
    }
}

Please Help.

Still Showing the same error we have modified our function as per your suggestion

public function excel()

    {
        $report = new Report;
        $report->run()->exportToExcel(array(
            'dataStores' => array(
                'unloadsPivot' => array()
            )
        ))
        ->toBrowser("myreport.xls");
    }

Please note that we are using Laravel 6 version.
