Pivot 300+ columns into one column

[happyds]

Hi,

I am in need of some help. Does anyone know if there is a relatively easy way to pivot 300 columns into rows within the one column. I have a file with 200,000 records and 300 columns. Does someone know of a better way to implement this solution other than using a Pivot Stage? If I use the pivot stage, I'm certain the job will take a huge performance hit and also there's a great chance of human error if I map each column into each output column. The following shows what the current data looks like and what I need it to be changed to.

Current Data:
Header Row Col 1 Col 2 Col 3 Col 4 Col 5 . . . Col 300
Row 1 A 1 20 50 20 30
Row 2 B 5 30 10 50 25
Row 3 C 7 50 20 80 5
Row 4 D 9 70 30 25 20
Row 5 E 15 80 70 15 10
.
.
.
Row 200,000 HH 25 65 25 10 50


TO BE:
Header Row Row 1 Row 2 Row 3 Row 4 Row 5 . . . Row 200000
Col 1 A B C D E HH
Col 2 1 5 7 9 15 25
Col 3 20 30 50 70 80 65
Col 4 50 10 20 30 70 25
Col 5 20 50 80 25 15 10
.
.
.
Col 300 30 25 5 20 10 50

Once I have pivoted the columns into rows I need to use the Header Row column to lookup to a table to pull back Ids to associate to each record.

I would appreciate any suggestions or help. Please let me know if you I need to clarify more.

Thanks!

There's no easy way. You just have to do it. Take short breaks occasionally. Save your work periodically so you can exit without saving if it all goes pear shaped at some point.
