This is a cross-category conversion from Document (Numbers Spreadsheet) to Image (ICO Icon). While these formats serve different purposes, Xonvert extracts the compatible data from your Numbers Spreadsheet source and maps it into the ICO Icon format. Document files typically contain Apple users for spreadsheets, while Image files are used for website favicons and Windows application icons. The conversion bridges these two domains, allowing you to repurpose your content across different workflows.
