Finally got a chance to test your snippet. Thank you for it!
I took the liberty of flushing it out a bit.
================
#!/---

import os
import win32com.client
excel = win32com.client.Dispatch( 'Excel.Application' )
excel.Visible=1 # shows the spreadsheet (can be handy)
xlCSV = 6
# substitute for list generation
list = ["c:\\temp\\test.xls", "c:\\temp\\test1.xls"]
for nm in list:
csv = os.path.splitext( nm )[0] + '.csv'
print "Procesing file:", csv
if os.path.exists(csv): # window$ won't auto overwrite
os.unlink(csv)
wb = excel.Workbooks.Open( nm )
wb.SaveAs( csv, xlCSV )
print wb.Close() # requires manual verification
# eliminating unattended runs
#wb.Exit() & wb.Quit() # generate ERROR(s) - no such thing(s)
# leaving Excel open
excel.Visible=0 # actually closes Excel if no sheet open
# verified via task manager
print "Check to see if this worked."
# end of file
=================
The above does in fact work.
Using the above I have a few questions.
Documentation on xlCSV came from where?
" on .Workbooks.Open(file.xls) came from ???
" on .SaveAs( filename, xlCSV ) came from ???
" on .Close() came from ???
MSDN has rather extensive documentation on the Excel object model,
although it is somewhat spread out. Search for "Excel object model".
I cheated on xlCSV. That's the name of the symbol, and I believe it
will even be available as win32com.client.constants.xlCSV after you
instantiate the application, but I just searched the web for "xlCSV" and
hard-coded the 6.
Tell me about the lack of the .Exit() and/or .Quit(), please.
Workbooks don't exit or quit. Workbooks can be closed, but exit is
something that applies to the application (excel, in your case). You
should also be able to say
excel = None
to get rid of the app.
I ran out of time today. Is it possible to send something like an
<enter> keystroke to a Window (<yes><no>) box if it accepts same from
actual keyboard? May not work anyway since .Close() hangs (in
interactive) awaiting it's answer.
The Workbook.Close method accepts parameters; you should be able to get
it to skip the dialog. I believe that wb.Close( False ) should do this.
==============
The wb.Close( False) works as predicted.
The excel = None leaves Excel open.
excel.Visible=0 does close it so I'm OK.
excel.Quit() is probably the better choice.
(learned via a comment above + Trial & Error)
For the next person that might have need of this:

Using the Python supplied CSV module now makes handling a variety of
.xls files a real snap. "Variety" of real spread sheet types, yes. The
butchered type that should have been done in Word - probably never.
Thanks again!
