Convert Exstream documents and CAD parts (NDO) online for free
The converter easily converts your NDO Documents and parts to various formats - free and online. No OpenText Exstream or or other Cad software needed.
To convert other file formats to the "Proprietary Output File" file type, you need software like OpenText Exstream or a similar tool.
The .ndo extension represents a frustrating collision of two very different proprietary standards, leaving most users unable to open their files without expensive, specialized software.
Most commonly, an .ndo file is a generated document output from OpenText Exstream. These are typically high-volume print streams or customer communication documents (like insurance policies or utility bills) saved in a raw format intended for industrial printers or archiving systems rather than end-user viewing. The friction here is high: standard PDF readers like Adobe Acrobat usually cannot interpret the proprietary tags or stream data inside an Exstream .ndo file, effectively locking the content away unless you have access to the original enterprise environment.
Alternatively, if you work in manufacturing or engineering, your .ndo file is likely a CAD/CAM part file created by Metalix cncKad. This format stores geometry and tooling data for CNC sheet metal punching and cutting. The problem is that .ndo is a closed format; you cannot open it in standard drafting tools like AutoCAD or SolidWorks.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NDO converter.
