    /**
    * @param array $row
    *
    * @return IlluminateDatabaseEloquentModel|null
    */

    private function transformDateTime(string $value, string $format = 'Y-m-d')
    {
        try {
                return Carbon::instance(Date::excelToDateTimeObject($value))->format($format);
            } 
            catch (ErrorException $e) 
            {

Answer 1

use use AppImportsDate; to PhpOfficePhpSpreadsheetSharedDate

then it will be

namespace AppImports;
use PhpOfficePhpSpreadsheetSharedDate;
use CarbonCarbon;
use AppVouchers;
use MaatwebsiteExcelConcernsToModel;
use MaatwebsiteExcelConcernsWithHeadingRow;
use MaatwebsiteExcelConcernsWithBatchInserts;
use MaatwebsiteExcelConcernsWithChunkReading;
use MaatwebsiteExcelImportsHeadingRowFormatter;

HeadingRowFormatter::default('none');

class VouchersImport implements ToModel, WithHeadingRow, WithBatchInserts, WithChunkReading
{
    /**
    * @param array $row
    *
    * @return IlluminateDatabaseEloquentModel|null
    */

    private function transformDateTime(string $value, string $format = 'Y-m-d')
    {
        try {
                return Carbon::instance(Date::excelToDateTimeObject($value))->format($format);
            } 
            catch (ErrorException $e) 
            {
                return Carbon::createFromFormat($format, $value);
            }
    }
