olebrowse is a simple GUI to browse OLE files (e.g. MS Word, Excel, Powerpoint documents), to view and extract individual data streams.
It is part of the python-oletools package.
If you provide a file it will be opened, else a dialog will allow you to browse folders to open a file. Then if it is a valid OLE file, the list of data streams will be displayed. You can select a stream, and then either view its content in a builtin hexadecimal viewer, or save it to a file for further analysis.
