Hi, I have an InputStream wrapped in a BufferedInputStream and I'm trying to detect whether it is a normal zip file or a xlsx file (and take appropriate actions accordingly). I have tried to use hasOOXMLHeader <https://github.com/apache/poi/blob/trunk/src/java/org/apache/poi/poifs/filesystem/DocumentFactoryHelper.java#L91> to achieve this. But it just checks if the input stream is a zip file and there is nothing specific for an xlsx file there. (I understand that xlsx is a zip file with a bunch of xml files).
Is it possible to detect if the inputstream is from xlsx file or a normal zip file?
