Set Header as First Row:
Using this function sets the header values of the file as the first row of data. Doing so will essentially add a first row to your dataset, and use the values that were in the file headers. The new file headers will be "A", "B", "C", etc.
This function is the opposite of the Set First Row as Header Function and can be used to undo an accidental execution of that function.
To set your header as first row, click the “Data Cleanup” button, then select “Set Headers as First Row”. Its that easy.
