Extract text from COMcheck or PhET files (CCK)
To convert CCK project files to another format, you need COMcheck or other Data software.
To convert other file formats to the "Compliance Project File" file type, you need software like COMcheck or a similar tool.
A .CCK file is primarily a Building Energy Compliance file created by the U.S. Department of Energy's COMcheck software. It contains structured project details, including building envelope, HVAC, and lighting specifications required to demonstrate compliance with commercial energy codes like ASHRAE 90.1. Secondarily, the extension is used for Circuit Construction Kit files generated by PhET Interactive Simulations, which are typically formatted as XML.
These formats present distinct challenges. The COMcheck .CCK file is a proprietary data container. It cannot be opened by standard text editors or web browsers, requiring users to install the specialized desktop app or use the web portal. This makes sharing raw project files with clients or inspectors who lack the software highly problematic. Users typically need to convert the data into a PDF to share official compliance reports. The PhET simulation files are also useless outside their specific educational applet, though their underlying XML structure means they contain readable plaintext.
Because COMcheck formats are highly specialized, standard online converters fail to process them. Often, only the original COMcheck software can properly read or export the structured data into a printable document. However, just drag and drop your file onto convert.guru to identify the exact format, view its internal contents, and convert it when possible. If our analysis detects a supported underlying or embedded format - such as the XML structure in PhET files - viewing or conversion to standard text formats may still be possible.
Convert.Guru analyzes your CCK file, detects the exact format, and lets you read the text inside.
Users also converted PTS, ACI and PDT files.

To convert files to CCK, try COMcheck or another comparable tool in the "Building Energy Compliance Data" category.
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 CCK converter.
