Excel Source

Applies to: SQL Server SSIS Integration Runtime in Azure Data Factory

The Excel source extracts data from worksheets or ranges in Microsoft Excel workbooks.

Important

For detailed info about connecting to Excel files, and about limitations and known issues for loading data from or to Excel files, see Load data from or to Excel with SQL Server Integration Services (SSIS).

Access Modes

The Excel source provides four different data access modes for extracting data:

  • A table or view.

  • A table or view specified in a variable.

  • The results of a SQL statement. The query can be a parameterized query.

  • The results of a SQL statement stored in a variable.

The Excel source uses an Excel connection manager to connect to a data source, and the connection manager specifies the workbook file to use. For more information, see Excel Connection Manager.

The Excel source has one regular output and one error output.

Excel Source Configuration

You can set properties through SSIS Designer or programmatically.

The Advanced Editor dialog box reflects all the properties that can be set programmatically. For more information about the properties that you can set in the Advanced Editor dialog box or programmatically, click one of the following topics:
