This sentence in python is a descending ranking counting the null values of each column of the data frame (df) .. it helps to understand the nulls presence in table df.isna().sum().sort_values(ascending = False) how can I do the same with Tableau ?

Thanks Vignesh,

Lets say our table has 12 columns (C1, C2, ... C12) and 1000 rows; each column could has many or few null values. How can we build a ranking of columns (fields) with the number (count) of null values that each column has.

Column Name Qty of Null values

C5 455

C10 399

C7 156

C4 25

C5 3

C1 0

C2 0

C3 0

C6 0

.....
