I am not able to import .xlsx file using maatwebsite Excel laravel

Can anyone help me to rectify this issue. Maat website is able to upload file with mime type application/vnd.ms-excel but it is not importing the file having mime type application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

When i save As the file with same name and extension its mime type is converted into application/vnd.ms-excel and then its data is easily imported into system
