Free online CWK to DOCX converter

Older AppleWorks or ClarisWorks word-processing files may need conversion before they can be edited in current office software or shared as Word documents. DOCX is supported by Microsoft Word and many other modern editors.

What the CWK format is

.cwk is a proprietary document extension used by ClarisWorks and its successor, AppleWorks, mainly on older Macintosh systems; some versions also ran on Windows. It can represent different document types, including word-processing files, spreadsheets, and drawings. The steps below apply to word-processing files only.

What the DOCX format is

DOCX is Microsoft Word’s Office Open XML word-processing format. It supports formatted text, styles, tables, and images, and is widely readable and editable in current office software.

How to convert CWK to DOCX

Online on 101convert.com

1. Upload the CWK file to the converter on this page.
2. Start the conversion to DOCX.
3. Download the converted file.

Several files can be converted as a batch. The page shows the per-file size limit. The conversion runs on the site’s server with LibreOffice.

Offline with desktop software

LibreOffice is free and runs on Windows, macOS, and Linux. It can open some ClarisWorks and AppleWorks word-processing files; support depends on the file variant and LibreOffice version.

1. In Writer, choose File → Open and select the CWK file. If it is not shown, set the file dialog to display all files.
2. Choose File → Save As, select Word 2007–365 (.docx) as the file type, and save. Confirm using the DOCX format if prompted.

Quality and compatibility

DOCX is a word-processing format; it will not preserve the spreadsheet, database, drawing, or presentation behavior of other AppleWorks document types. Even with a word-processing file, review page breaks, fonts, tables, and images after conversion: legacy formatting may not have an exact DOCX equivalent, and missing fonts can change line wrapping. If LibreOffice cannot open the file, its CWK variant may not be supported.
