-In the latest Microsoft Excel update, Excel documents containing Pivot tables were experiencing corruption when created or resaved using XlsIO. This was due to a change in Excel’s handling of the Pivot table XML structure-specifically, the count attribute, which was previously optional, is now required. This issue has been resolved. XlsIO now ensures that the count attribute is correctly included in Pivot table definitions, maintaining compatibility with the latest Excel update and preventing file corruption.
