Question details

The user needs to use Excel VBA to generate and correctly format month and year headers for a PivotTable that is linked to an Access database.

Product: Microsoft Excel
Device & OS: not provided
Scenario: Creating correctly formatted month and year headers (e.g., mmm-yyyy) for a PivotTable programmatically via VBA.
Observed behavior: Excel automatically changes the desired date format unless the cell is explicitly set to display the value as text.

Before you start

Ensure that your workbook is saved as a Macro-Enabled Workbook (.xlsm) and that you have the Developer tab enabled to access and run VBA code.

Solution 1Recommended

Format PivotTable Headers as Text Using VBA

Explicitly set the cell's number format to Text before writing the formatted date value to prevent Excel from auto-converting the strings.

When inserting date values into cells using VBA, Excel often attempts to apply its default system date formatting. By explicitly formatting the target cell as Text ('@') beforehand, you force Excel to accept and display the exact string generated by your VBA code.

Open the VBA Editor

Press Alt + F11 to open the Visual Basic for Applications (VBA) editor in your workbook.

Locate the Target Macro

In the Project Explorer, find and double-click the specific module or sheet containing the macro that generates your PivotTable headers.

Set Cell Number Format to Text

Before assigning the date value, use the .NumberFormat = "@" property on the target cell to convert it to text format.

Assign the Formatted Value

Assign the value using the VBA Format function. For example: With Worksheets("Report_IW_INSTALLED_BASE").Cells(6, i) .NumberFormat = "@" .Value = Format(DateSerial(Year(AnalysisStartingData), Month(AnalysisStartingData) + i - 2, 1), "mmm-yyyy") End With.

Formatting Order Matters: Applying an 'Mmm' format after a value is already written as text will not change the displayed value. Always set the NumberFormat to '@' first.

Frequently Asked Questions

Why do my VBA dates change format when inserted into Excel cells?

Excel automatically detects date values and applies its default system date format. To bypass this automatic conversion, you must explicitly set the cell's NumberFormat property to Text ('@') before assigning the date string.

Can I apply formatting directly to the PivotTable fields instead of the cells?

Yes, you can use .PivotFields("FieldName").NumberFormat = "mmm-yyyy" if the header is recognized as a standard Date field within the PivotTable itself. However, if you are writing custom headers to worksheet cells surrounding the table, formatting the specific cells as text is required.

What does the '@' symbol mean in VBA NumberFormat?

In Excel VBA, the '@' symbol is the format code used for Text. Applying it to a cell ensures that any data entered subsequently is treated strictly as a text string, bypassing any mathematical or date-based automatic formatting.
