Using an Excel map file to replace concepts in Excel source file

Thank you, @takbb
Is it possible to determine rows-to-exclude dynamically?
Maybe something like this: find a cell with value “Year” - take the row of this cell (if it is found), and exclude all rows before the row.

I can imagine that the source can add an extra row of empty cells or split table’s title into two rows - and if something like this happens - my whole workflow will crash.
