Let say you have the following data table with 6 digits numbers in one column (Number 1) and you are interested in extracting only 4 numbers from those 6 numbers into a new column (Derived Numbers). How do you go about doing that? Thanks in advance.
| Number 1 | Derived Numbers |
|---|
| 201409 | |
| 201589 | |
| 201378 | |
| 201411 | |
| 201091 | |
