In Laravel you can use validate the file upload with extension using After Hooks. Read more from here!

$validator->after(function ($validator) use ($request){
    if($this->checkExcelFile($request->file('file')->getClientOriginalExtension()) == false) {
        //return validator with error by file input name
        $validator->errors()->add('file', 'The file must be a file of type: csv, xlsx, xls');
    }
});

function checkExcelFile($file_ext){
    $valid=array(
        'csv','xls','xlsx' // add your extensions here.
    );        
    return in_array($file_ext,$valid) ? true : false;
}
