I've created an easy to use product export module which is free to download and use.
Export Products v1.0
* Choose what to export by dragging and dropping from available fields.
* Choose how you want the export ordered by easily sorting the selected fields.
* Save an export so you can load your chosen fields again later.
* Clean easy to use interface.
* Language Select.
* Delimiter option.
Updated to work with prestashop 1.4.
Changed the export to stream the file instead of saving to disk. Should fix file permission problems.
Changed the export folder to the upload folder in the root of prestashop to avoid permission issues.
Added support for prestashop 1.1.
Hopefully fixed permissions problems by creating a seperate directory for csv file on install.
Fixed reinstall issues by adding a DROP if exists before the tables are created on install.
Download: Export Products v1.0
Please remember it should work for most versions of prestashop if not all. Also backup your database before doing any export/imports.
