- Device & OS
- not provided
- Scenario
- Working with Excel workbooks where a specific worksheet suddenly goes missing and formulas start returning errors linked to the Analysis ToolPak.
- Observed behavior
- Formulas reference FUNCRES.XLAM or show #REF! errors, and the missing worksheet appears to be stuck or hidden inside the FUNCRES.XLAM add-in.
Before attempting recovery, ensure that your workbook is completely saved and make a backup copy of your current file to prevent any further data loss during the unhiding process.
Unhide the Worksheet from the Analysis ToolPak Add-in
Locate the hidden worksheet within the FUNCRES.XLAM file and copy it back to your original workbook.
FUNCRES.XLAM is the background file for the Excel Analysis ToolPak. Sometimes, users accidentally move or hide worksheets within this add-in file instead of their active workbook, leading to broken references.
Open Microsoft Excel and ensure the Analysis ToolPak add-in is active by checking Developer > Excel Add-ins.
Navigate to the 'View' tab on the Excel ribbon and click on 'Unhide' in the Window group. If FUNCRES.XLAM contains the hidden worksheet, select it from the list and click 'OK'.
Right-click the unhidden worksheet tab at the bottom of the screen, select 'Move or Copy', choose your original workbook from the 'To book' dropdown menu, check the 'Create a copy' box, and click 'OK'.
Return to your original workbook and update any formulas that still reference the FUNCRES.XLAM add-in or show #REF! errors so that they point to the newly copied local worksheet.
