Hello Kalpna Bindal,
I just investigate this issue and use the following way but it does work:
private void Button_Click(object sender, RoutedEventArgs e)
// initialize connection
OleDbConnection con = new OleDbConnection();
con.ConnectionString =
"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\\Fruits1.xltm;Extended Properties=\"Excel 12.0 Xml;HDR=YES;\"";
//pass query to Insert values into Excel
OleDbCommand cmd = new OleDbCommand();
cmd.CommandText = "insert into [Sheet1$] values('')";
cmd.Connection = con;
// EXECUTE QUERY
con.Open();
cmd.ExecuteNonQuery();
con.Close();
I then did a research about this issue and find the following case:
http://stackoverflow.com/questions/22225017/reading-excel-xltm-files-programmatically
To test whether it is possible I use the following code in WPF:
Microsoft.Office.Interop.Excel.Application xltmApp = new Microsoft.Office.Interop.Excel.Application();
xltmApp.Visible = false;
xltmApp.ScreenUpdating = false;
Workbook xltmBook = xltmApp.Workbooks.Open(@"D:\Fruits1.xltm");
Worksheet xlworksheet = xltmBook.Worksheets.get_Item(1);
for (int i = 1; i <= 1; i++)
for(int j=1;j<=1;j++)
string str = (string)(xlworksheet.UsedRange.Cells[i, j] as Microsoft.Office.Interop.Excel.Range).Value;
MessageBox.Show(str);
The result is that I can read this .xltm file and read the firstline without problem.
I would think you can also use this way to work with your .xltm file and output it to your application.
For more details about how to fill to your WPF, common wpf and excel thread will be helpful:

By the way, for WPF case please post on WPF forum instead of C# forum.Best regards,
