How to add 20k products to Magento?

[Boby]

I need to remove the old products from my Magento store and add approximately 20000 new
products. Maybe somebody knows how can I do that in a fast and easy way.
Thank you very much.

File2cart can do that easily. You can easily delete all the store data and also import
new entities without any problem. Check the info here - http://www.file2cart.com/supportedcarts/

Magento database structure is complex so bulk import needs to be done with lot of care
Our experience is : automated systems like file2cart are very expensive for bulk upload
where as ready tools available on Mangento extensions mostly are beta versions with bugs. Invariably they time our when applied
you need to get it done through custom programming
