Insert is not working / Excel

Question

I created a process to make a Insert in a spreadsheet on EXCEL but the data is not being entered. No error is returned.

Code:

private void AtualizarPerformanceEntrega()
{
    try
    {

        DataTable dt = ExportPerformanceEntrega();

        //string sFileXLSX =  @"C:\Entrega\Performance.xlsx"; //ConfigurationManager.AppSettings["ExportPerformanceEntrega"]
        if (File.Exists(@"C:\Entrega\Performance.xlsx"))
        {
            string strConnXLSX = (@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Entrega\Performance.xlsx; Extended Properties='Excel 12.0 Xml;HDR=YES;ReadOnly=False';");

            foreach (DataRow row in dt.Rows)
            {
                using (OleDbConnection connection = new OleDbConnection(strConnXLSX))
                {

                    string strSQL;
                    OleDbCommand cmd;
                    //OleDbDataReader dts;
                    if ((string)row["StatusEntrega"] == "No Prazo" || (string)row["StatusEntrega"] == "Fora do Prazo" || (string)row["StatusEntrega"] == "Antes do Prazo")
                    {

                        if (dt.Rows.Count > 0)
                        {
                            strSQL = "INSERT INTO [BaseEntregue$] " +
