I'm trying to avoid the text file - import to excel - mechanism, since there is quite a lot of files written. Best regards Marin Again, not python ( hope I don't start a flame war, I've just joined the list John Machin suggested--it looks very interesting). I have used Apache Cocoon for this kind of task. Everything important happens server-side. Your raw data could be stored in a database, or a flat file, or not stored persistently at all--just be created as a virtual stream if you can use your python/fortran utility as a web service. It goes into the cocoon pileline, and is first turned into XML. Then it is turned into other XML (in this case most likely the gnumeric format). Lastly it is serialized into Excel format, given the appropriate Mime type, and sent to your browser. It is only when it gets to the Browser, that a decision is made as to what to do with it. You can set up your Browser to open it is MS Excel (whichever one you have), Open Office, Gnumeric, or whatever. Most of them will cope with it perfectly, and will be able to save it locally in their most up-to-the-minute variation, if that is what you want.

The rd in xlrd is a contraction of ReaD. As far as I have used PyExecelerator, it can only *create* xls file. I can't imagine why you would think that the extent to which you have used pyExcelerator has any bearing on its capabilities. In any case pyExcelerator has an ImportXLS.parse_xls function, which is rather embryonic compared to that of xlrd. I'm viewing the xlrd sources, but I can't find the file loading function and there is no examples about it. The file loading function of xlrd is called open_workbook and is in __init__.py. Have you considered reading the documentation for xlrd? Have a look at the file runxlrd.py, which not only acts as a diagnostic and dump utility, but also is a fairly rich source of examples of what you can do with the Book object returned by xlrd.open_work_book(). Could you possibly be viewing the source for xlwt (wt being an abbreviation of WriTe)? xlwt is a fork of pyExcelerator. In the current version in svn, ImportXLS has been so severely deprecated that it has vanished, which might explain why you can't find a file loading function.

You can't make MS Office to work. There is no way to do so. Even asking MS the question why something does not work costs a lot of money and you don't get a solution.

After that you just want things to work, and if they don't work, there are people who are paid $/per hour to make it work. And that applies *exactly* the same to Excel as OpenOffice, except that you're not paying the cost for the software and the licences and tracking the licences. If you can find a package that just works for writing to Excel, great. Otherwise you have to build it yourself. And that's when you have to decide whether you want to spend 40 hours of programmer time (less than one programmer-week) trying to get write support for Excel in order to save two hours of support time for OpenOffice. -- Steven -- http://mail.python.org/mailman/listinfo/python-list

What I was needing (aiming for) was a way to write to excel 2003 files. write to a file has connotations of updating an existing file; write a file or create a file are less ambiguous. Formatting is not necessary, since what I'm trying to write is some tabular data; results from fortran-python simulation (I can explain, but the details seem irrelevant for this case). I'm trying to avoid the text file - import to excel - mechanism, since there is quite a lot of files written. I suggest that you join the python-excel group (http:// groups.google.com.au/group/python-excel?hl=en) or at least read some of the questions and responses. Please, one more question. As you have noticed, I posted my message to comp.lang.python, using a newsreader. I hadn't noticed; what makes you think so? Is there a way to access google groups through a similiar interface program as a newsreader. I don't know (question has never arisen before). Never used them before, and getting a lot of messages to my email every day does not sound very appealing to me. Either (1) you have not looked at the messages at the link that I gave you or (2) your idea of a lot of messages every day differs wildly from mine. Email alternatives are (a) one message per posting (b) daily digest (c) none (use your web browser). HTH, John -- http://mail.python.org/mailman/listinfo/python-list

You had no hesitation to write code that relies on people having Excel installed, and yet you didn't want to rely on an open source free software package that anyone with a fast Internet connection or a CD drive can install in just a couple of minutes. You don't even need to reboot the PC. Consider that there are parallel universes to yours, where big brother severely limits access to the Internet, where staff have to sign rather draconian agreements about their use of the company facilities, where desktops are scanned nightly for contraband (the finding of which will cause the brownshirts to drop in for a quick game of hands- knees-and-bump-your-exe), where even the mention of seditious material like OpenOffice might result in a trip to the desert provinces for re- education ... the cause is better advanced IMHO by staying under the radar and crawling under the wire; tub-thumping soapbox-mounting ranters however correct and righteous are likely to suffer a fate similar to that of Michael Servetus.
