How to Open InDesign CS5.5 in CS3

To be able to open an Adobe InDesign CS5.5 file in CS3 there are a couple steps you need to do:

  • First, open the InDesign CS5.5 file in CS5.5 and export the file as an IDML (InDesign Markup Language) file, using the Export options from the File menu.
  • Then in CS4 open this IDML file and export it to an .inx file. This file will now open up in InDesign CS3.

If you don’t have Adobe InDesign CS5.5 and CS4, we offer a InDesign down-saving service to help open the file into the CS version you require.
