File mode incompatibility is usually caused by opening a file made by an old version in a new version of Excel. You only need to change the storage format of the file to solve it. The steps are as follows:
1. Click the “WPS table” column in Excel.
2. Select the “File” option in the wps form drop-down menu.
3. Select “Save As” or press the shortcut key “ctrl+shift+s” to proceed.
4. Save as and change the format to “xlsx”, then close and reopen the file to close the compatibility mode.
