In this article I will discuss about import and export wizard tool. Import and export wizard is the easiest tool to import data or export data from sources to destinations. Sources and destinations can be either SQL server, DB2, Oracle, Excel, flat files or access database.
Import and export wizard uses SSIS framework internally and provides a wizard to import or export data. The complete process done by the wizard can also be saved as an SSIS package.
Import and export wizard can be opened in the below mentioned ways.
- Click on start button select import and export wizard under SQL server installation program
- In SQL server management studio, Right click on database and select import data or export data under tasks options based up on the type which you are doing
- Another option is to open wizard is right click on SSIS folder in BIDS/SSDT environment and selecting import and export wizard.
- You can also open the same wizard by providing command dtswizard.exe on the command prompt or run prompt.
You can choose any of the options to open import and export wizard. Wizard opens with welcome screen as pasted in Figure 1. Irrespective of the operation(import or export) you are performing, the welcome screen is same which explains what can be done using this tool.

Click on next button which opens Source wizard screen where you need to provide source information such as source type and required data base or files. Source connection is the one from which data will be exported.
Options on the data source wizard will be changed based up on the type of data source selected.
Figure 2 shows the options displayed when SQL Native client 10.0 selected as Data source. When SQL native client data source selected, you need to provide server name, authentication type and data base to fetch data

Figure 3 shows the options displayed when Microsoft Excel selected as Data source. Excel file location should provided to export data.

In the same way, you need to provide all required fields based up on the data source selected.

Figure 5
Click next button after providing source and required options. Destination wizard will be displayed as shown in Figure 6.
In Destination wizard, you need to provide destination data source and required options. All the data sources which are available in source wizard are available in destination wizard as well.
