Re: c++-code for reading and writing in .gnumeric files

[John Gill <jng earthenware-services org>]

If you are wanting to write gnumeric files you could also try:

http://www.earthenware-services.org/earthenwarewiki/PworkBook

For small sheets this works pretty well.

I guess it would be handy to have something that parses an existing gnumeric file and creates a pworkbook object from it, then you'd be sorted (I suspect this is easier to write than do, although something that did a reasonable job for simple sheets probably wouldn't be a lot of work).

If you need xls you can just use ssconvert (part of gnumeric) to convert your gnumeric sheets to xls + if/when the gnumeric->pworkbook utility is written you would have everything you need.
