Hi,
Using Excel's Data > Get & Transform tool, this should be easy to solve
- Type a heading in cell A1
- Select A1:A4 and press Ctrl+T
- Click on cell A2 and go to Data > Get & Transform > From Table
- In the Query Editor window, right click on the heading of the table and select Split column > By delimiter > Advanced Option > By rows > OK
- Right click on the heading > Transform > Clean
- Click on Close & Load
Hope this helps.
