Excel 2013 does not recognize data as Date type data after you import the data from a SQL Server data source to an Excel workbook

Applies to: Excel 2013


Consider the following scenario:
  • You use the Microsoft SQL OLE DB Provider to import data from a SQL Server data source to a Microsoft Excel 2013 workbook.
  • The SQL Server data source contains a Date type column.
  • You use the data to create a PivotTable in Excel 2013.
  • You try to insert a timeline into the PivotTable.
In this scenario, you cannot select the cell range that contains the data in the Insert Timeline dialog box.


This issue occurs because the SQL OLE DB Provider returns the String data type if the data source contains a Date, Time, or DateTime2 type column. In this situation, Excel 2013 cannot recognize the data as the Date type.


To work around this issue, use one of the following methods:
  • Change the column type to DateTime in the SQL Server data source.
  • Use an Open Database Connectivity (ODBC) driver to import the data.
