How to Export SQL Server Tables from Database to Excel File Dynamically in SSIS Package by using Script Task - SSIS Tutorial

Scenario: Download Script

You are working as ETL Developer / SSIS Developer or maybe Dot Net Developer. You got this requirement where you have to Export all the Tables from SQL Server Database to Excel File. Each Table should be export as SchemaName_TableName as Sheet to single Excel File.

So let's say you have 10 user tables in a Database and you would like to export all of them. The SSIS Package should be able to create an Excel File( You can provide File Name in variable_DateTime) and this excel file should have 10 sheets, one for each table and load the data. 

If you will return the SSIS Package, it will create new Excel file with Sheets equal to user tables in our database. 

In excel, I am creating all the fields as Text Data type.  If you would like to chose few tables, you can change the query inside script task that returns list of tables from database.

Log File Information : In case your SSIS Package fail. Log file will be created in the same folder where your Excel File will be created. It will have the same datetime like your Excel File.


We are going to use Script Task in our SSIS Package to create an Excel file and export all tables data to it from SQL server Database.

Step 1:Create new SSIS Package and Variables
Create an SSIS Package by using SQL Server Data Tools. Once SSIS Package is created, create variables as shown below.

FolderPath: Where you would like to create an Excel File
ExcelFileName: The name of Excel file you would like to create

Step 2: Create ADO.NET Connection in SSIS Package to use in Script Task
Create ADO.NET Connection Manager so we can use in Script Task to get tables data to export to Excel. This ADO.Net connection should be pointing to Database that we want to export to an Excel File.

Step3: Add Variables to Script Task to use from SSIS Package
Bring the Script Task on Control Flow Pane in SSIS Package and open by double clicking Check-box in front of variable to add to Script Task.

Step 4: Add Script to Script task Editor in SSIS Package to Export All Tables from SQL Server Database to Excel File
Click Edit Button and it will open Script Task Editor.
Under #region Namespaces, I have added below code
using System.IO;
using System.Data.OleDb;
using System.Data.SqlClient;

Under public void Main() { 
I have added below code. 

            string datetime = DateTime.Now.ToString("yyyyMMddHHmmss");

                //Declare Variables
                string ExcelFileName = Dts.Variables["User::ExcelFileName"].Value.ToString();
                string FolderPath = Dts.Variables["User::FolderPath"].Value.ToString();
                ExcelFileName = ExcelFileName + "_" + datetime;

                OleDbConnection Excel_OLE_Con = new OleDbConnection();
                OleDbCommand Excel_OLE_Cmd = new OleDbCommand();

                string connstring = "Provider=Microsoft.ACE.OLEDB.12.0;" + "Data Source=" + FolderPath + ExcelFileName
                    + ";" + "Extended Properties=\"Excel 12.0 Xml;HDR=YES;\"";

                //drop Excel file if exists
                File.Delete(FolderPath + "\\" + ExcelFileName + ".xlsx");

                //USE ADO.NET Connection from SSIS Package to get data from table
                SqlConnection myADONETConnection = new SqlConnection();
                myADONETConnection = (SqlConnection)(Dts.Connections["DBConn"].AcquireConnection(Dts.Transaction) as SqlConnection);

                //Read list of Tables with Schema from Database
                string query = "SELECT Schema_name(schema_id) AS SchemaName,name AS TableName FROM   sys.tables WHERE  is_ms_shipped = 0";

                SqlCommand cmd = new SqlCommand(query, myADONETConnection);
                DataTable dt = new DataTable();

                //Loop through datatable(dt) that has schema and table names

                foreach (DataRow dt_row in dt.Rows)
                    string SchemaName = "";
                    string TableName = "";
                    object[] array = dt_row.ItemArray;
                    SchemaName = array[0].ToString();
                    TableName = array[1].ToString();

                    //Load Data into DataTable from SQL ServerTable
                    // Assumes that connection is a valid SqlConnection object.
                    string queryString =
                      "SELECT * from " + SchemaName + "." + TableName;
                    SqlDataAdapter adapter = new SqlDataAdapter(queryString, myADONETConnection);
                    DataSet ds = new DataSet();

                    //Get Header Columns
                    string TableColumns = "";

                    // Get the Column List from Data Table so can create Excel Sheet with Header
                    foreach (DataTable table in ds.Tables)
                        foreach (DataColumn column in table.Columns)
                            TableColumns += column + "],[";

                    // Replace most right comma from Columnlist
                    TableColumns =("["+ TableColumns.Replace(",", " Text,").TrimEnd(','));
                    TableColumns = TableColumns.Remove(TableColumns.Length - 2);

                    //Use OLE DB Connection and Create Excel Sheet

                    Excel_OLE_Cmd.Connection = Excel_OLE_Con;
                    Excel_OLE_Cmd.CommandText = "Create table [" + SchemaName+"_"+TableName + "] (" + TableColumns + ")";

                    //Write Data to Excel Sheet from DataTable dynamically
                    foreach (DataTable table in ds.Tables)
                        String sqlCommandInsert = "";
                        String sqlCommandValue = "";
                        foreach (DataColumn dataColumn in table.Columns)
                            sqlCommandValue += dataColumn + "],[";

                        sqlCommandValue="["+sqlCommandValue.TrimEnd(',') ;
                        sqlCommandValue = sqlCommandValue.Remove(sqlCommandValue.Length - 2);
                        sqlCommandInsert = "INSERT into [" + SchemaName+"_"+TableName + "] (" + sqlCommandValue +") VALUES(";

                        int columnCount = table.Columns.Count;
                        foreach (DataRow row in table.Rows)
                            string columnvalues = "";
                            for (int i = 0; i < columnCount; i++)
                                int index = table.Rows.IndexOf(row);
                                columnvalues += "'" + table.Rows[index].ItemArray[i] + "',";

                            columnvalues = columnvalues.TrimEnd(',');
                            var command = sqlCommandInsert + columnvalues + ")";
                            Excel_OLE_Cmd.CommandText = command;

                Dts.TaskResult = (int)ScriptResults.Success;

            catch (Exception exception)
                // Create Log File for Errors
                using (StreamWriter sw = File.CreateText(Dts.Variables["User::FolderPath"].Value.ToString() + "\\" +
                Dts.Variables["User::ExcelFileName"].Value.ToString() + datetime + ".log"))
                    Dts.TaskResult = (int)ScriptResults.Failure;


Step 5: Save your SSIS Pakcage and Execute to Export All Tables form Database to Excel File
 I will suggest you to test this package in dev and other environments to calculate time. As it is going to export each table from database and sometime database are really big, it can take long time. I had small database on my laptop and it worked fine.
