KNIME Automation: Generate Product Descriptions from Excel + PDFs

I want to build a KNIME automation that processes an Excel file row by row and, for each product, searches multiple PDFs for relevant information using the product name or article number. Based on the extracted PDF content, it should automatically generate a product description and write it back into the Excel output. Right now, the matching is unreliable (content doesn’t match the product) and the Excel row order/columns sometimes get lost.

Please help.
