Import data from Excel to SQL Server table

Introduction

In this tutorial, you will learn how to import data from an Excel file into a SQL Server table. This process is essential for data management and integration, allowing you to leverage the data stored in spreadsheets within a relational database environment. By following these steps, you will be able to streamline your data handling and improve your workflow.

Step 1: Prepare Your Excel File

Before importing data, ensure your Excel file is properly formatted:

• Headers: Make sure the first row contains column names that match the SQL Server table.
• Data Types: Verify that the data types in Excel are compatible with those in SQL Server (e.g., dates in Excel should be formatted as dates).
• Remove Unnecessary Data: Delete any blank rows or columns that are not needed for the import.

Step 2: Open SQL Server Management Studio

Launch SQL Server Management Studio (SSMS) to begin the data import process:

• Connect to Your Database: Use your credentials to connect to the SQL Server instance where you want to import the data.
• Select the Database: Choose the database that contains the target table.

Step 3: Use the Import Wizard

Utilize the SQL Server Import and Export Wizard:

• Right-click on the Database: In the Object Explorer, right-click the database, select "Tasks," then choose "Import Data."
• Choose a Data Source: In the wizard, select "Microsoft Excel" as your data source.
• Browse for Your Excel File: Locate and select the Excel file you prepared earlier.

Step 4: Configure the Destination

Set up the destination for the imported data:

• Select Destination: Choose "SQL Server Native Client" as the destination.
• Specify Server and Database: Ensure you're connected to the correct server and database.

Step 5: Map the Data

Map the Excel columns to SQL Server columns:

• Select Source Tables and Views: Choose the relevant sheet from your Excel file.
• Edit Mappings: Click on "Edit Mappings" to align the Excel columns with SQL Server table columns. Ensure the data types match.

Step 6: Run the Import Process

Execute the import operation:

• Review the Summary: Check the summary of your import settings.
• Run the Import: Click "Finish" to start the import process. Monitor the progress and ensure there are no errors.

Step 7: Verify the Imported Data

Once the import completes, verify that the data has been correctly imported:

• Query the Table: Use a SELECT statement to check the data in the SQL Server table:

  SELECT * FROM YourTableName;
  

• Check for Missing or Incorrect Data: Ensure all expected records are present and formatted correctly.

Conclusion

You've successfully imported data from Excel to SQL Server. This process can significantly enhance your data management capabilities. For further learning, consider exploring additional SQL Server features or automating the import process using SQL Server Integration Services (SSIS).
