Extract text from Kneura Canvas files (CNX)
To convert CNX Canvas files to another format, you need Kneura Teach or other Data software.
To convert other file formats to the "Proprietary XML Data File" file type, you need software like Kneura Teach or a similar tool.
The .CNX file extension represents several entirely different data formats, making it exceptionally frustrating to manage. Most frequently, it functions as an XML-based digital whiteboard scratchpad created by Kneura Teach. In other industries, it acts as a data file for WinWerth coordinate measuring machines, a GPS navigation route for VDO Dayton devices, a construction job file from Tripod Data Systems, or a legacy game graphics file for Puyo Puyo titles.
The primary disadvantage of a .CNX file is its severe fragmentation. Because multiple unrelated developers chose the exact same extension, operating systems cannot reliably assign a default application to open it. Furthermore, the format is highly proprietary in its structure. Even when the underlying code is standard XML, opening the file in a text editor only reveals unformatted coordinates, text nodes, or vector points that require the original software to render correctly. Users trying to share Kneura whiteboards or VDO GPS routes face a major roadblock because standard web browsers and document viewers cannot read these proprietary schemas.
If you need to share a .CNX file, your best conversion targets depend entirely on its origin. For GPS data, converting to GPX or KML is ideal. For whiteboard sessions, exporting to PDF or PNG from within the native application is strictly required to preserve visual fidelity. Standard online converters fail universally with .CNX files because they cannot parse the conflicting proprietary data structures.
Because this file format is difficult to open or convert natively, third-party software often corrupts the data. If our analysis detects a supported underlying XML structure, we can safely extract the raw text and help you pinpoint exactly which software generated your specific file.
Convert.Guru analyzes your CNX file, detects the exact format, and lets you read the text inside.

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 CNX converter.
