Import CSV to Magento with parser & SEO links

need to import some projects from a CSV file into magento. I would need this done as soon as possible. I am using Magento community 1.7.0.2. The products need to be input using some sort of parser. Instructions for the parser from the previous hosts are provided in the quote below. “ Thanks for sending this through. I believe perhaps I should have included an annotation with the csv file to better explain how things have been arranged. The idea is to have this as a platform agnostic/easily consumable format which anyone can interrogate and implement a simple parser for. So a brief explanation on the dataset. The key columns you need to be aware of are: "Sequence", "Type" and "Handle" *Sequence*: Logical grouping of data types where 1 == the product attributes 2 == Variations of the product (e.g. small, medium, large, etc) 3 == Product Images 4 == Collections or categories the product belongs to *Type*: As per above, Product, Variations, Images and Collections *Handle*: The uinque identifier for a product. This is the glue for all the various data types related to a given product. Unfortunately, we are not able to have the data exported in a different format but can send an updated csv if required. “ SEO Links Old product links from the existing site sitemap will 301 redirect to the correct product pages for the magento version of each product. For example : [login to view URL] (old site product url) if visited, after the transfer, will redirect to [login to view URL] (Magento product url)
