Update specific cell of excel file using oledb

Question

I want to update the specific cell of the excel file using oledb. Say I7 cell, for some reason always I1 is getting updated. Can anyone tell me what's wrong with this code?

OleDbConnection oledbConn = new OleDbConnection(connString);
oledbConn.Open();

// I want to set the value of I7 cell to 22, for some reason value is I1 is getting updated :(
OleDbCommand cmd = new OleDbCommand("UPDATE [" + sheetName + "$I7:I7] SET F1=22", oledbConn);
int result = cmd.ExecuteNonQuery();
Console.WriteLine(result);
oledbConn.Close();

Answer 1

I ran the same program on excel 2007, it worked smoothly. For excel 2013 it does not work. Seems like a bug in excel 2013.

This may purely be an issue with the cell address scheme you're using. Try $I$7:$I$7 intsead. Also, what is that F1 thing in the query?
