1.2 Implementation ideas

Use the self-service dataset "Add column" and implement it through "formula/function".

Note: This paper lists some common conversion methods, which will be supplemented according to the actual data structure.

2. Operation steps

2.1 Add columns in self-service dataset

Add a self-service dataset, select the numerical field under the corresponding dataset (this file takes the fixed data value 1621221876057 as an example), click "+" to add a new column, as shown in the following figure:

Note: the functions and fields in the formula box need to be selected by clicking the selection area on the left, and cannot be entered manually.
