Excel API for C/C++

qtrahul

Another available option is to attempt to extract the code from an open source excel reading competitor.

Open Office - http://www.openoffice.org/ - is likely to be used,

Gnumeric is probably a better option.
Excel code is here - http://git.gnome.org/browse/gnumeric/tree/plugins/excel

Libxls
libxls is a C library which can read Excel (xls) files. It has been tested on Linux x86 and Cygwin but may work on any little-endian system. ...
"libxls.sourceforge.net":http://libxls.sourceforge.net

Thanks for the link Yash, it looks promising. It could be a good start and maybe I find some time to make a Qt version.

What's about KOffice? As far as I know they use MS -> OOo -> KOffice, but they might have a cuter API to the OOo routines since they are Qt-based.

goetz

KOffice falls out due to license issues - unfortunately.

Thanks - corrected * 2 :-)

Has anybody figured out what kind of license is? GPL, LGPL, ... ?

I would like to include all the "open source" tools/libraries we talk about into wikis so when needed one can find them in one place.

EDIT: What are the KOffice license issues?

goetz

From http://www.koffice.org/contribute/:

bq. KOffice is released under the LGPL v2+ (and GPL v2+ for some parts).

Why was that a problem then? Can't get much more flexible than that (unles you are looking for the one part that is only GPL and you want to release a closed source app).

EDIT: before I get screamed at: warning: I don't have any idea of the details about "v2+"

goetz

I'd have to extract the parts I need, remove the KDE stuff (not available on Windows and Mac) and publish it as a new LGPL project. We do not have the time for that at the moment and it's not on top of the want-have list of the customer.

fcrochik

I see.... so the issue is not exactly with the license...

goetz

The license is one of the issues. Nevermind, I have some hints I will dig into further if I ever have some spare time.

Volker, as your successes with excel?
I use libxls, but some excel's files in russian language not read correctly (I realized because of the inability to convert data from a file in UTF-16). If you have any achievements, can you tell us about them?

goetz

I did not look into libxls yet, so sorry, no advice from my side.

Jupiter

is there also something for word documents (*.doc or *.docx)?

You could maybe take a look at "http://www.libxl.com/":http://www.libxl.com/

That lib was already mentioned on the first page of this topic.

Jupiter

mogz

oops! the post was meant for the main title. guess i'll have to take my time next time. sorry for that
