An Overview of File Component in Talend Open Studio

Functional Odoo 16

In Talend, each component generates Java code that handles its specific tasks behind the scenes. To access these components, you can use the Palette window, which serves as a hub for over 900+ components organized into groups. This window streamlines the process of finding and selecting the components you need to build your data integration and transformation workflows, making your data management tasks more efficient and user-friendly.

We can see the tFileInputExcel component in the screenshot above. That component will extract all data from Excel to log while running this job, you can drag and drop the component repository to the designer view, type the name of the component in the designer view, and set the property type.

To do that, we want to import Excelsheet from SystemFile to the Talend metadata repository, and under the component, we can set the file name or stream.
