If you get InDesign CC files, but have CS5–CS6, you can access Creative Cloud content, by using the MarkzTools2 file conversion app from Markzware:

Is your workflow based on InDesign CS5 or InDesign CS6 (Creative Suite), yet needs to open InDesign CC (Creative Cloud) documents? You can do so, with an application from Markzware.

Markzware develops affordable, time-saving solutions for print, publishing, and graphic arts users around the world. MarkzTools2 is a stand-alone file conversion application for the macOS platform. This app by Markzware can convert a newer version InDesign document to an IDML file, which can be read by InDesign CS4 and newer InDesign versions.

MarkzTools2 allows you to open recent InDesign versions, such as CC-CC 2018, in IDML, readable by less recent versions of InDesign, such as CS5-CS6. See a demonstration, by watching this video:

Get InDesign CC Files, But Have CS5-CS6? Access Creative Cloud Content

Markzware’s MarkzTools2 is a full-version application that converts newer InDesign version documents (including CC, CC 2014, CC 2015, CC 2017, and CC 2018) into an IDML file. You can open the IDML file in InDesign CS5 or CS6. MarkzTools2’s “If IDML Exists” section allows you to replace or not replace an existing IDML or to create a new IDML using a unique filename.

You can convert a document to IDML by either dragging the document icon to the main window in MarkzTools2. As an alternative, you can find and choose a document using the File -> Convert menu. When complete, the IDML file will be added to the File -> Recent menu.

If you need to open an INDD CC file in an lower version of InDesign, you can easily use MarkzTools2 to convert the file to IDML. MarkzTools2 is quite capable of converting your InDesign CC document to the InDesign Markup Language file format, in quick time.

MarkzTools [bundle] has two components: A set of plug-ins for InDesign (see below) plus a standalone conversion tool, by which you can convert almost any InDesign to IDML files. IDML-files can be directly imported in InDesign Versions (CS4 and higher).

MarkzTools bundle benefits offer:
• allows users to convert InDesign to IDML, independent of Adobe’s Creative Cloud.
• can create an IDML from any version InDesign file, including a CS5, CS5.5 or CS6 version. (InDesign can only create an IDML for CS6 and above.)
• is simple to operate.
• lets you choose or create the folder in which MarkzTools2 creates the IDML.
• is very fast. (It takes less time than for InDesign to send your document to a server and return an IDML.)

InDesign CS5 Tip:
Beginners, or even seasoned users who are new to using a specific tool, will appreciate the new Tool Hints panel, which tells you the basic function of each tool and how the tool’s behavior will change if you hold down modifier keys.
