Last week for work, this little tool saved the day! I created an Indesign file with Adobe CC on my work computer, and needed to open it on my personal computer. While I do have access to Adobe Creative Cloud on both, apparently Indesign's latest software update is not available for all IOS systems - Leaving me unable to open my file.
Luckily, I found this website that will convert your Indesign files (no matter the version it was originally created on) and convert them into idml files for free! Let me tell you, this worked like a charm.
Anyways, too good not to share-- check it out. http://ixsaveback.de/idsb/web/service/index_en.jsp
