I am currently working in IBM Business Automation Workflow (BAW) and need assistance implementing a feature where users can upload an Excel file and display its contents in a table within a Coach view.

Here is a detailed description of what I am trying to achieve:

1. Goal:

   • To enable users to upload an Excel sheet through a file upload control in a Coach view.
   • Once the file is uploaded, its contents should be read and displayed in a table on the same page.

2. Challenges I Am Facing:

   • I have added a file upload control in my Coach view, but I am unsure how to process the uploaded Excel file to extract its data.
   • I am looking for the best approach to parse the Excel file and bind its data to a table control.

Could you please guide me on:

1. The steps required to implement this functionality in IBM BAW.
2. Whether any specific libraries or tools are needed for Excel file processing in this environment.
3. Best practices for handling file uploads and displaying data securely and efficiently.

Your assistance in this matter would be greatly appreciated. Please let me know if you need further details or clarification.
