I am using Apache POI 3.7, to ensure that I'm able to datamine some Stand out excel spreadsheets. However, some excel spreadsheets contain embedded documents for example Word paperwork, emails etc..
Now through this tutorial: http://poi.apache.org/spreadsheet/quick-guide.html#Embedded you'll be able to see whether the Stand out spreadsheet consists of embedded documents or otherwise but in the workbook level.
However, I question if you'll be able to determine whether a specific cell contained inside a spreadsheet consists of an embedded document instead of in the workbook level.
I have looked and looked with no success, any pointers could be apprecited.
