Convert XLS to XLW

Understanding XLS and XLW file formats

XLS is the default file format for Microsoft Excel workbooks created in versions prior to Excel 2007. It stores spreadsheet data, including formulas, charts, and formatting, in a proprietary binary format. XLW is an older Excel file format used primarily as a workspace file. Instead of storing spreadsheet data, XLW files save the layout and arrangement of open workbooks, allowing users to restore their workspace setup.

Why convert XLS to XLW?

Converting an XLS file to XLW is useful if you want to save your current Excel workspace, including the arrangement of multiple XLS files, for later use. However, note that XLW files do not contain actual spreadsheet data but only references to open workbooks and their window positions.

How to convert XLS to XLW

There is no direct file conversion from XLS to XLW as XLW files are not data containers but workspace descriptors. To create an XLW file from your XLS workbooks, follow these steps in Microsoft Excel:

1. Open all the XLS files you want to include in your workspace.
2. Arrange the windows as desired.
3. Go to File → Save Workspace.
4. Choose a location and enter a file name, then save as XLW.

This will create an XLW file referencing your open XLS files and their arrangement.

Best software for XLS to XLW conversion

The best and most reliable software for this process is Microsoft Excel itself, as it natively supports both XLS and XLW formats. No third-party converter is recommended, since XLW files are specific to Excel's workspace management.

Important notes

• XLW files do not store spreadsheet data; they only reference the arrangement of open workbooks.
• Ensure all referenced XLS files remain in their original locations for the XLW workspace to function correctly.
• XLW is an older format and may not be supported in future Excel versions.
