Scenario: You have a dataset with columns column6 and column7 containing string values, and you want to ensure all entries in these columns are exactly 5 characters long.


Configuration:


Column Name: column6

Value: 5

Mostly: 100%

Outcome:


If any value in column6 is not exactly 5 characters, it will be flagged, and discrepancies will be listed in the output.

Scenario: You want to check if the numeric columns column1 to column5 have consistent integer values without any floating-point numbers in column2.


Configuration:


Column Name: column2

Mostly: 100%

Outcome:


Any non-integer values in column2 will be flagged, ensuring data type consistency across integer and double columns.
