OpenCart Community

Can anyone please tell me if CSV Import is broadly similar to Export/Import tool? I need to upload lots of products but I am suffering PHP memory issues with the latter and don't want change my webhost. I am currently using Opencart 1.5.2.1 with Opencart-1-2-1-x-export-import, I so far have around 1000 products and my Excel doc is 1MB.
Many thanks,
David

I'm new to this, but I've seen two extensions for this:

1. is free: http://www.opencart.com/index.php?route ... sion_id=17

2. Costs $15 http://www.opencart.com/index.php?route ... on_id=4943

Hope this helps! I'm trying the free one

Hope that helps
