About CWK files

The .CWK extension denotes a document created by ClarisWorks, which was later rebranded as AppleWorks. This classic integrated suite was a staple of computing in the 1990s and early 2000s, capable of storing word processing text, spreadsheets, databases, and vector drawings within a single file structure.

Because Apple discontinued AppleWorks in 2007, opening these files on modern devices is a major challenge. Current versions of macOS and Windows do not include native support, and even modern Apple productivity tools like Pages, Numbers, and Keynote dropped support for .CWK import after iWork '09. This proprietary lock-in leaves users with inaccessible digital history - old memoirs, financial records, or drawings - that appear as unreadable binary blobs.

To recover your content, you must convert the file based on its internal data type:

For Text Documents: Convert to DOCX or RTF to edit in Microsoft Word or Google Docs.
For Spreadsheets: Convert to XLSX or CSV for compatibility with Microsoft Excel.
For Drawings: Convert to PDF or JPG to preserve the visual layout for archiving.

convert.guru simplifies this process, allowing you to drag and drop your legacy .CWK files and instantly convert them to modern standards without needing to emulate an old operating system.

Use Convert.Guru to open and convert your CWK file.
