How can I export data from an excel file to a excel template?

So I have a question,

I have a xlsx file with 10+ column and every row has some data.
3 of those columns are declaration_date, invoice_number and total_declared_amount.
I also have a invoice template in xlsx with macros

So I would like to export every row into a xlsx file using the invoice template.

How can I get this done.
Maybe some tools?

Please help me out

The easiest way will be by using a simple macro which will in a loop (row by row) take content of these cells in given row, write them to template file and save the template file us regular workbook with specified in a macro filemane (may be a name consisting of declaration date and invoice number will be a good idea).

It's really basic macro, but if you need help with it, see the yellow banner above and attach (with all sensitive infromation removed) sample files.
Just few rows of a source file and the template (can be amost empty with clearly marked cells which shall be filled by data from the source).
