iWork to Office auto format change
Euan Williams The article offers a folder action script for automatically converting Pages files dropped into a folder, so removing the need to 'save as' or 'export' the files each time.
QUOTE:
When run, Pages opens the file or files that have been added to the folder and resaves them in Word format on the Desktop. As it does so, the Pages file extension is stripped out of each and replaced with Microsoft Word's. This script only works on Pages 09, but if you want to convert Pages 08, replace the part of the script that refers to "Microsoft Word 97 - 2004 Document" and replace it with "SLDocumentTypeMSWord", and it can be easily adjusted to do similar conversions for Numbers or Keynote.
