Mac MVP James Gordon has
posted directions on how to convert old Word (.doc) files to (.docx) files using an Automator workflow.
What does this converter do?
You choose one (.doc) file, several (.doc) files, or an entire folder filled with (.doc) files and the converter will save a copy of each Word file in standard open XML file format, better known as the “new” (actually more than 5 years old now) Word (.docx) format. This converter works with regular Word documents that do not contain macros.
Requirements: This workflow requires Microsoft Office 2011 Home & Business. The Office 2011 Home & Student version does not contain Automator workflows.
[Note: Updates to Office for Mac 2011 have broken the Automator actions used in this workflow. Send Microsoft feedback if you would like to see Automator support fixed. http://www.microsoft.com/mac/product-feedback]
