Hello,

I am trying to move multiple rows and copy them in just a single row; something like the following:

Input arrangement:

row1 20 30 40 50

row2 60 70 80 90

row3 100

and I would like to move row2 and row3 to the row1, like:

Output arrangement:

row1 20 30 40 50 60 70 80 90 100

My spreadsheet has more than 60K rows, so I am looking for a suitable way of doing it faster. Could you help me with it?
