How to write data into Excel file and save it? EPPlus C# - asp.net

Question

I have the code to execute multiple stored procedures from SQl. However, I am having an issue on how to write the data from the stored procedures into the Excel file. After writing the data into the excel file, I would like to save the Excel workbook. How can I achieve this? Any help is very much appreciated.
This is what I have so far:
public static void ExecuteStoredProcedures()
{
using (SqlConnection connection = new SqlConnection("Data Source=the connection goes here.."))
{
SqlTransaction transaction;
connection.Open();
transaction = connection.BeginTransaction();
try
{
SqlCommand cmdOne = new SqlCommand("exec ", connection);
SqlCommand cmdTwo = new SqlCommand("exec", connection);
SqlCommand cmdThree = new SqlCommand("exec", connection);
cmdOne.ExecuteNonQuery();
cmdTwo.ExecuteNonQuery();
cmdThree.ExecuteNonQuery();
transaction.Commit();
}
catch (Exception ex)
{
transaction.Rollback();
connection.Close();
}
}
}
public static void SaveExcelFile()
{
string SheetLocation = ConfigurationManager.AppSettings["SheetLocation"];
if (!System.IO.Directory.Exists(SheetLocation))
{
System.IO.Directory.CreateDirectory(SheetLocation);
}
ExecuteStoredProcedures(); //Should I call the method to load the data that comes from the stored procedures? Or what should I do to write the data into the file?
var newFile = new FileInfo(#"C:\Users\");
using (ExcelPackage xlPackage = new ExcelPackage(newFile))
{
xlPackage.Save();
}
}

Get data from stored procedures in the form of a Dataset or DataTables.
Create worksheet:
using (ExcelPackage xlPackage = new ExcelPackage(newFile))
{
ExcelWorksheet ws = xlPackage.Workbook.Worksheets.Add(AnyName);
}
Loop in Datatable rows and columns like a 2d array and create cells in the worksheet and add data in the created cells:
int rowIndex = 0
foreach (DataRow DataTableRow in dt.Rows)
{
int colIndex = 1;
rowIndex++;
foreach (DataColumn DataTableColumn in dt.Columns)
{
var cell = ws.Cells[rowIndex, colIndex];
cell.Value = DataTableRow[DataTableColumn.ColumnName];
colIndex++;
}
}
