Ruby on Rails

Datashift has template generation for any active record model to csv or excel, for example to create a csv template for a Spree product :

thor  datashift:generate:csv -m Spree::Product --result /tmp/spree_products.csv

You can also export the headers with data via datashift:export:csv

$ more /tmp/spree_products.csv

id,name,description,available_on,deleted_at,slug,meta_description,meta_keywords,tax_category_id,shipping_category_id,created_at,updated_at,promotionable,meta_title,discontinue_on

This gives the required columns into Spree. You can copy the data from your export into the correct Spree fields, the final file can then be imported  via

thor datashift:import:csv -i /tmp/spree_products.csv -m Spree::Product

N.B Spree data model and requirements are complex, simple import may not be enough, you may need to write a few helpers or extend  datashift:import, the README and Wiki are quite extensive
