You can try export of desktop application - Store Manager for Magento .
Here is free 2 weeks trial version available - http://www.magentocommerce.com/magento-connect/store-manager-for-magento.html
Also please specify your requirements to import - do you need it to be scheduled or need the file to be placed on FTP or locally?
I will enumerate a couple of advantages of export via Store Manager over ordinary default export:
- using Store Manager you can choose which exactly fields to export and where to place the exported file.
- also you can save settings for export for further exports to do in couple of clicks.
- you can export locally using Store Manager on bridge connection. In this way you can avoid server overload.
- you can export either to .csv file or to Excel.
