I don't recall ANY Python Excel reader/writer that can handle embedded
scripting. They all only read the last value active in a cell, not the code
behind the cell. They mostly just bypass the need to convert to/from
CSV/TSV.
Presuming you are doing this on Windows, you might be able to use
either the pywin32/win32py extension library, or ctypes, to invoke the
Excel COM interface -- which may allow you to read the underlying script
and/or form objects.
If this is a one-time operation, it may be faster to just open the
files and use cut&paste <G> Or write a large VBA script in Excel.
This appears to be the current "favored" package from Python:
https://openpyxl.readthedocs.io/en/stable/
You may still have problems:
"""
keep_vba controls whether any Visual Basic elements are preserved or not
(default). If they are preserved they are still not editable.
"""
If not editable, you won't be able to copy from one file to another.
Also:
"""
openpyxl does currently not read all possible items in an Excel file so
images and charts will be lost from existing files if they are opened and
saved with the same name.
"""
It does, however, grant access to the formulas in cells, rather than
just last value; along with style information...
