How to Export Data to Multiple Excel Sheets from Single SQL Server Table in SSIS Package - SSIS Tutorial

Scenario: Download Script

You are working as ETL developer or an SSIS developer. You have a table let's say dbo.TotalSale. Once of the column in this table is Region. You would like to create an Excel file with Multiple Sheets, each for Region Value. 

If there are three distinct Regions values in Region Column, it should create an Excel file with three excel sheets. 

So if tomorrow, the Region decreases or increases, the sheets should be created according to distinct values.

In your scenario, you can chose any column that you would like to use for dividing the table data to multiple sheets.

How to create multiple Excel sheets from single SQL Server Table in SSIS Package - SSIS Tutorial


Solution:

We are going to use Script Task in SSIS Package to create multiple Excel Sheets for single Table data depending upon the distinct value from a column. 

Step 1: Create new SSIS Package and create Variables 
Open your SSDT ( SQL Server Data Tools) and create new SSIS Package. Once done, create below variables as shown.

ColumnNameForGrouping : Provide the column you would like to use for creating sheet data
ExcelFileName : Provide the excel file name you would like to create
FolderPath: Provide the Path where you would like to create excel files
TableName: Provide the table name with schema from which you like to get data

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 sheets in Excel File. 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 Data from single SQL Server Table to Multiple Excel Sheets in Excel File
Click Edit Button and it will open Script Task Editor.

Step 5: Save the script and Run SSIS Package to create Multiple Sheets from single SQL Server Table
Hit save button and then close the script task editor window. Run your SSIS Package and it should create an excel file with multiple sheets depending upon unique regions from region column.

I ran my SSIS Package for above table, and here is my Excel file with multiple sheets.
