Generate numbered string

The Generate numbered string masking activity allows you to generate numbered strings.

Table of contents


To use the Generate numbered string masking activity, it must be placed inside a table masking activity or a similar activity that iterates over data. Once placed, select the property you want to mask. Generating a numbered string requires you to enter the format of the masked value and optionally, a number generator that is going to be used to generate values.


In this example we want to generate values that consist of a random number between 0 and 100 and the key word test. First we place the Address masking activity into opened Package.xaml and put the Generate numbered string masking activity within it. Once placed, we select the City property that we want to mask with generated numbered strings. We enter "{0} test" as the format and new RandomNumberGenerator(0,100) for the number generator. .
