The supplied data appears to be in the OLE2 Format.

The supplied data appears to be in the OLE2 Format. You are calling the part of POI that deals with OOXML (Office Open XML) Documents. You need to call a different part of POI to process this data (eg HSSF instead of XSSF)

在做Excel导入功能时，发现导入的文件报错，代码中判断了文件类型：

// IO流读取文件
InputStream input = file.getInputStream();
//解析xls
HSSFWorkbook wb = new HSSFWorkbook(input);
//解析xlsx
XSSFWorkbook wbx = new XSSFWorkbook(input);

但是依旧报错：

org.apache.poi.openxml4j.exceptions.OLE2NotOfficeXmlFileException: The supplied data appears to be in the OLE2 Format. You are calling the part of POI that deals with OOXML (Office Open XML) Documents. You need to call a different part of POI to process this data (eg HSSF instead of XSSF)

网上查询也都是版本问题。

后来反复测试，发现xls导入没问题，但是将文件后缀直接改成xlsx导入就会报错。

将文件另存为xlsx后，再次导入，就不在报错了。

总结：

修改文件类型时最好使用另存为，避免出现版本问题。
