Description

Opens an ExcelWriter template spreadsheet. A template is a file created in Microsoft Excel that contains data markers where data source values will be inserted.

C#
vb.net

Parameters

templateFileName
The complete path and file name of the template Excel file.

Exceptions

ArgumentNullException
Open will throw this exception if null (C#) or Nothing (VB.NET) is passed to the method.
ArgumentException

Remarks

If your template file is the new Office Open XML (.xlsx) format, you can pass it into the Open method just as you would a BIFF8 (.xls) Excel file. You will need to remember to give the output file a ".xlsx" extension when you call Save, as ExcelWriter cannot convert .xlsx files to .xls.
