Is it possible to import outlined data from Excel?
This is where Excel shows drill-down [+] [-].
Reading from ODBC doesn’t give parent/child info; neither does exporting to CSV; export to HTML gives this info via mso-outline-level styles, but 2007 version puts actual content into subfolder and users will be VERY confused trying to select an appropriate file.
I ended up parsing .mht file exported from Excel, it has the required structure in form of tr tags and mso- attributes.
