Convert CWK SPREADSHEET to OTS

The CWK file extension, specifically related to ClarisWorks or AppleWorks Spreadsheets, is a proprietary format used by Apple's productivity suite for spreadsheet data. Originating in the early 1990s, this format allowed users to create and edit spreadsheets on both Mac and Windows platforms. Although AppleWorks was discontinued in 2004 and this format was replaced by NUMBERS, These CWK files can still be opened by older versions of Apple's iWork applications.

The OTS (OpenDocument Spreadsheet Template) file extension, maintained by the Organization for the Advancement of Structured Information Standards (OASIS), is used to create spreadsheet templates with predefined styles and formatting in Apache OpenOffice Calc. Introduced in 2005, OTS files facilitate the creation of consistent and reusable templates for tasks like budget planning and invoicing. These files are XML-based, compressed as ZIP archives, and compatible with various open-source spreadsheet applications.
