2)All the atributes are assigned to every single product, so say I have a dress in small, medium and large. Now all the other atributes are there as well in the excel file, so now I have a dress with S,M,L,XL,RED,BLUE,WHITE,34,36,38, S/M,M/L,L/XL ......and it go's on. So now I have reached the maximum imported column in excel. (256 pc).
1. This is not really a limitation of this code, but you could try my latest code update, which has this option to handle just the product models and attributes. That would probably save a few columns. If you still have excess columns, you could try to hack the code to make it handle 1 language or 1 attrib set, at a time (just a thought!).
2. Well, attributes are not actually assigned to every single product. Attributes are assigned to a product, only if the corresponding value price cell contains a "non-empty" value. Otherwise, the attribute options/values are listed beside each product, but are not assigned to them.
If you think your tab-delimited file is messed up in any way, you could email it to me (just make sure you zip or tgz it... I'm on a slow dial-up ).
