How can Azure Data Factory Data Flows dynamically process multiple Excel sheets in a ForEach loop?

“How can Azure Data Factory Data Flows be configured to dynamically process multiple Excel sheets within a ForEach loop, including the necessary steps to set up the loop, parameterize the datasets, and handle the sheet names dynamically?”

To dynamically process multiple Excel sheets in a ForEach loop using Azure Data Factory Data Flows, you can follow these steps:

Create a Dataset for Excel Files: Define a dataset that points to your Excel file location. Ensure the dataset is parameterized to accept sheet names dynamically.

Add a Lookup Activity: Use a Lookup activity to read the sheet names from a "Cover sheet" or a sheet that lists all the sheet names in your Excel file. This will provide a collection of sheet names that you can iterate over.

Configure the ForEach Activity: Add a ForEach activity to your pipeline. Set the Items property to the output of the Lookup activity, which contains the sheet names.

Parameterize the Dataset: Parameterize the dataset to accept the sheet name dynamically. This allows the dataset to read data from different sheets based on the sheet name provided by the ForEach loop.

Add a Copy Activity: Inside the ForEach loop, add a Copy activity to process each sheet. Use the parameterized dataset to specify the sheet name for each iteration.
