# Array Character Scramble A version of the [Character Scramble](https://docs.tonic.ai/app/generation/generators/generator-reference/character-scramble) generator that can be used for array values. This generator replaces letters with random other letters, and numbers with random other numbers. Punctuation and whitespace are preserved. For example, for the following array value: `["ABC.123", 3, "last week"]` The output might be something like: `["KFR.860", 7, "sdrw mwoc"]` This generator securely masks letters and numbers. There is no way to recover the original data. ## Characteristics

## How to configure To configure the generator, toggle the **Consistency** setting to indicate whether to make the generator self-consistent. By default, the generator is not consistent. If [Structural data encryption](https://docs.tonic.ai/app/generation/generators-assign-config/generators-data-encryption-config) is enabled, then to use it for this column, in the advanced options section, toggle **Use data encryption process** to the on position.
