how to transpose a large data from columns into rows

[Holly]

I have a large data file, it has all monthly sales qty by column, I need to
combine them with another data file, with has all monthly data by row. Both
data files have same columns such as SKU, Price, and Unit of Measurement. Is
there a formula to transpose the monthly data into rows in the first file?

Look at Text to Columns under the Data menu.

It only does one column at a time, I need to convert all 12 months at once
quick, because all the input data (month by column) is changes constantly, I
need to convert them quickly in few minutes or less than half hour.

Is there a way to do above quickly?
