xlrd support for Excel 2007 XLSX files (was Re: [pyxl] Re: Excel 2007 and dates)

2009-11-24T02:00:09Z

The stage I'm up to is where xlsx support is a bolt-on, not integrated
into the main package [next stage: big refactoring]. Neither
formatting_info=True nor on_demand=True is supported.
The current bolt-on kit (xlsxrd.py and runxlsxrd.py) is available (on
application) to serious alpha testers.

Sure did. Not sure what to search for. "Excel 2007" seems to bring
up some discussions saying that work is underway and asking for test
cases. Perhaps you can enlighten me, and I can provide some test
cases in return.

That would be Excel 2007...but now that I look again, I realize that

Excel 2007 and dates

2009-11-23T20:25:11Z

I've got a bunch of Excel 2007 spreadsheets that I need to parse. As
far as I can tell from searching around, there is no release of xlrd
that will do this yet. (Although I'd be quite willing to use a
development branch, if someone is working on it and willing to share.
I could not find a code repository either.)

Re: merging sheets

2009-11-20T08:20:44Z

See xlutils.copy and/or xlutils.filter. Both are covered in the tutorial.
As I've said several times now, for xlutils.filter to grow this ability
would require a lot of work that would need funding.

I am working with the RTD functions in excel using pythoncom and a

am able to create my python object via the IRTDServer com interface.
Excel then passes a callback interface, IRTDServerEvents to my
object. I hold on to that interface and callback using UpdateNotify

No "unicode" is expected. I presume that you mean UTF-16. Please share
the details of your diagnosis, including what leads you to point the
finger at the data rather than (1) xlrd's failure to understand the data
layout (2) the file-creating software's failure ditto.
