@Ryan Hi Ryan, I haven't seen this particular error before, but googling turn up this link which leads me to think you encountered a versioning issue between Python and the Win32 extensions. From the link the solution is to erase the autogenerated files under C:/Python26/Lib/site-packages/win32com/gen_py/ Good luck --- Dan Thanks --- Dan

After invoking excel, I get the following error when I try to open a new workbook with the excel.Workbooks.Add() command…

Traceback (most recent call last):
File “”, line 1, in
wb = xl.Workbooks.Add()
File “C:\Python26\lib\site-packages\win32com\gen_py0020813-0000-0000-C000-000000000046×0x1×5.py”, line 27289, in Add
File “C:\Python26\lib\site-packages\win32com\client\__init__.py”, line 94, in Dispatch
assert UnicodeToString is None, “this is deprecated and will go away”
AssertionError: this is deprecated and will go away

Any idea why this is happening?

Thanks,
Ryan

[...] The program begins with the standard boilerplate: import the win32 module and start Excel. If you have questions on this, please refer to the earlier posts. [...]

Hi Paul,

To answer your questions, you can use something like:

ws.Range(”B1:B5″).NumberFormat = “@”

to format cells as Text. See the next post at http://www.pythonexcels.com/2009/10/mapping-excel-vb-macros-to-python/ for a walkthrough on how to capture the appropriate Excel Visual Basic command in a macro and map it into Python.

Could you provide an example for formatting cells as text? Thanks. This blog is fantastic.
