As announced in MC1072405 (May ’25), we’re retiring Organization Data Types in Microsoft Excel for Microsoft 365. This change simplifies the data types experience and encourages use of more robust, supported solutions like Power BI and custom Excel add-ins.

This change will take effect on July 31, 2025.

[How this affects your organization:]

Starting July 31, 2025:

• Organization Data Types will be removed from the Data Types gallery on the Data ribbon tab in Excel.
• Users will no longer be able to convert values to new organization data types.
