+# Does XlsIO prefix PivotTable calculated field headers with "Sum of"?
+
+Yes. When a calculated field is added to a PivotTable, Microsoft Excel automatically prefixes the column header with **Sum of** before the original name. For example, a field named **Profit** becomes **Sum of Profit**. XlsIO follows the same behavior to remain consistent with Excel.
