Try giving full path of the xls file instead of relative path. –shahkalpesh May 4 '11 at 7:12 It is in the same directory. It must be this way. I shouldnt give the full path. –Shansal May 4 '11 at 14:04 I know that's not what you are asking for but you should try the xlrd module instead of using win32com.

How can I decode this error message? Is there a table somewhere that allows me to convert this numerical error code into something more meaningful?

The first item in your stack trace (the number) is the error code returned by the COM object. The second item is the description associated with the error code which in this case is "Exception Occurred". pywintypes.com_error already called the equivalent of win32api.FormatMessage(errCode) for you. We'll look at the second number in a minute. By the way, you can use the "Error Lookup" utility that comes in Visual Studio (C:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools\ErrLook.exe) as a quick launch

A few comments: Firstly, you have two variables workbook and workBook that differ only by one capital letter. Probably not a good idea. Secondly, there is no reason to grab the ActiveWorkbook as you already have a reference to it on the previous line (an opened workbook is immediately active). Thirdly, you do not specify a path for your filename, so if your python code and excel worksheet are in different directories, Open will fail. Finally, perhaps sheetno is out of range. Excel holds sheets in a 1-based array. –Steven Rumbalski Sep 15 '10 at 15:41 add a comment| 2 Answers 2 active oldest votes up vote 4 down vote This error occurs because the COM object you're calling will reject an external call if it's already handling another operation. There is no asynchronous handling of calls and the behavior can seem random. Depending on the operation you'll see either pythoncom.com_error or pywintypes.com_error. A simple (if inelegant) way to work around this is to wrap your calls into the COM object with try-except and, if you get one of these access errors, retry your call. For some background see the "Error Handling" section of the chapter 12 excerpt from Python Programming on Win32 by Mark Hammond & Andy Robinson (O'Reilly 2000). There's also some useful info specifically abo

The poor advice I can offer is (1) for your own piece of mind, see if you can get the same basic behaviour with wscript and a .vbs script, (2) to try and see if you can find a similar problem in any language/environment (eg, wscript) and how they worked around it and finally (3) see if you can worm around it by catching that exception then discarding the object you have and re-connecting to that instance using normal Dispatch().
