**Overlay Matching Columns from Excel1 into Excel2 dynamically**

📌 Objective

Create a KNIME workflow that:

• Reads data from two Excel files:

Excel1: Source file with ~60 columns (contains data)

• Excel2: Template with ~5 columns (column names to retain + possibly empty rows)

For each column in Excel2:

• If a column with the same name exists in Excel1 → copy data from Excel1 into that column in Excel2

• If no matching column in Excel1 → leave the column in Excel2 as-is (blank or default)

📤 ➤ The structure of Excel2 must remain exactly the same — only data should be filled in where matching columns exist in Excel1.
