Excel for the web does not support the creation of folders or sub-workbooks within a single workbook, so far I know. The feature you are looking for, which is the ability to group sheets into sub-workbooks or folders for organizational purposes, is not available in Excel for the web.
In Excel, grouping sheets into sub-workbooks or folders is a feature that is typically available in the desktop version of Excel, and it allows you to create a hierarchy for better organization. However, this feature is not available in Excel for the web, which is a web-based, simplified version of Excel designed primarily for basic spreadsheet editing and collaboration.
If you require this specific functionality, you would need to use the desktop version of Excel to create sub-workbooks or folders within your Excel workbook. Once you have created these sub-workbooks, you can use Excel for the web for basic viewing and editing, but the organizational structure will be maintained in the desktop version.
Keep in mind that Microsoft regularly updates its Office 365 suite, including Excel for the web, so it is possible that new features may have been added since my last update. I recommend checking the most recent version of Excel for the web to see if this feature has been introduced. The text were edited with the help of AI.
