Convert ClarisWorks documents (CWK) online for free
The converter easily converts your CWK documents to various formats - free and online. No AppleWorks or or other Text software needed.
To convert other file formats to the "ClarisWorks Document" file type, you need software like AppleWorks or a similar tool.
A .cwk file is a legacy proprietary document created by AppleWorks (formerly ClarisWorks). It functions as a container format that can hold word processing text, spreadsheets, databases, paintings, or vector drawings.
Apple abandoned the .cwk format in 2007. It is a completely dead standard. As of 2013, Apple officially stripped backward compatibility from modern apps like Pages and Numbers. You cannot natively open a .cwk file on modern macOS or Windows. Because the internal binary structure is proprietary and largely undocumented, your legacy data is effectively locked in a black box unless you rely on third-party reverse-engineering tools like the libmwaw library built into LibreOffice. Even then, complex formatting, macros, or database modules are rarely preserved perfectly intact.
To rescue your data, you must convert the file. For word processing documents, convert to DOCX or ODT to restore editability in modern software. For legacy spreadsheets, use XLSX. If your goal is simply to archive or read the content without altering it, PDF is the most robust solution. Drop your file here to view and convert it securely right in your browser - no need to track down an obsolete PowerMac to recover your work.

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 CWK converter.
