Question details

The user needs to update the year on an Excel calendar, but the calendar header formula references a separate, seemingly non-existent worksheet named 'Year'.

How to Update an Excel Calendar Year Using VLOOKUP and Hidden Sheets

Product: Microsoft Excel
Device & OS: not provided
Scenario: Updating a dynamic calendar year where a VLOOKUP formula retrieves month names and combines them with a year stored on a separate worksheet.
Observed behavior: The formula appears to reference itself or a missing location, but it is actually pointing to cell B1 on a hidden worksheet named 'Year'.

Before you start

Ensure your workbook is not password-protected, as structural protection may prevent you from unhiding worksheets to access the referenced cells.

Solution 1Recommended

Unhide the Referenced Worksheet and Update the Year Value

To update the calendar, reveal the hidden worksheet where the year data is stored and change the value in the specific cell.

Often, template designers hide settings sheets to keep the workbook interface clean. If a formula references a sheet name you cannot see, it is likely hidden.

Check for hidden worksheets

Right-click on any visible worksheet tab at the bottom of your Excel window.

Unhide the 'Year' sheet

Select 'Unhide' from the context menu. In the Unhide dialog box, select the 'Year' worksheet (and the 'Listes' sheet if you need to modify month names) and click OK.

Update the year value

Navigate to the newly revealed 'Year' worksheet, locate cell B1, and enter your desired calendar year.

Verify the calendar update

Return to your main calendar sheet. The VLOOKUP formulas should now retrieve the updated year and properly combine it with the month names.

Unhide the Referenced Worksheet and Update the Year Value

Tip: Once the year is successfully updated, you can right-click the 'Year' worksheet tab and select 'Hide' again to protect it from accidental edits.

Frequently Asked Questions

Why can't I click the 'Unhide' option when right-clicking a sheet tab?

The 'Unhide' option may be grayed out if the workbook's structure is protected. Go to the Review tab and click 'Protect Workbook' to enter the password and remove the protection before unhiding sheets.

How does VLOOKUP combine data from different sheets?

VLOOKUP can search for a value in one sheet (like 'Listes') and return corresponding data. By using the ampersand (&) operator or the CONCATENATE function in your formula, you can merge this VLOOKUP result with the year value from the 'Year' sheet in a single cell.

Can I hide the referenced worksheet again without breaking the formula?

Yes, hiding a worksheet only removes it from view. All formulas referencing cells in that hidden worksheet will continue to calculate correctly and update your calendar header without errors.
