有现成的代码你可以直接运行(在php环境下)：html页面：

Filename:

upload_file.php：

<?phpif ((($_FILES["file"]["type"] =="application/vnd.ms-excel")|| ($_FILES["file"]["type"] =="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"))){if ($_FILES["file"]["error"] > 0){echo "Return Code: " .$_FILES["file"]["error"] ."
";}else{echo "Upload: " .$_FILES["file"]["name"] ."
";echo "Type: " .$_FILES["file"]["type"] ."
";echo "Size: " . ($_FILES["file"]["size"] / 1024) ." Kb
";echo "Temp file: " .$_FILES["file"]["tmp_name"] ."
";if (file_exists("upload/" .$_FILES["file"]["name"])){echo $_FILES["file"]["name"] ." already exists. ";}else{move_uploaded_file($_FILES["file"]["tmp_name"],"upload/" .$_FILES["file"]["name"]);echo "Stored in: " ."upload/" .$_FILES["file"]["name"];}}}else{echo "Invalid file";}?>

这个就可以实现选择具体的数据类型，但是有兼容问题，我在测试的时候只有Opera，Chrome能用，火狐和IE都不兼容
