Here are some useful ideas for WBmerge
Combine monthly bank or credit card statement downloads into a single Excel file. So many websites only allow you to download one month of data rather than a broad date range. WBmerge can combine all those months together.
Take a report with multiple customers data and break out a separate Excel file for each customer. Think of WBmerge as a report distribution tool.
Read-only users of cloud based reporting services like Power BI can take an extract of their data and slice it up as needed.
You can take a single Excel file though the Merge process and create a new Excel file with only the data you want in the order you want it in. And you can create a template of your desired file state for quick reuse in the future.
