This tutorial shows how to use Excel templates so generated workbooks keep the expected structure, formatting, formulas, and layout. It is the sensible option when the spreadsheet already looks right and you only need to replace the data.
What You Will Learn
- Use an Excel template in an ETL workflow.
- Generate repeatable Excel output without rebuilding the workbook layout.
- Preserve expected workbook layout and formatting.
- Use templates for reports, invoices, and recurring spreadsheet output.
Before You Start
Prepare the Excel template before wiring it into the workflow. Templates are cheaper than explaining why the finance report changed shape overnight.
