Newbi question, if i have a table where i want to splitt a collumn into two how woud I do that.
Existing format
Column a , Column B, Column C
Index,0,0
2022-01,100,245
2022-02,101, 145
2022-03, 90, 200
North,0,0
2022-02,23, 123
2022-03,35,250
South,0,0
2022-01,87,100
Now I need to isolate the column a and the heading values, Index, North, South and make a new column
Column a , Column B, Column C, New Column
Index,0,0,index
2022-01,100,245, index
2022-02,101, 145, index
2022-03, 90, 200, index
North,0,0, north
2022-02,23, 123, north
2022-03,35,250, North
South,0,0, South
2022-01,87,100, South
The source can be an excel or a db table. Target is a db table
How do I do that?
