# Array Character Scramble A version of the [Character Scramble](/app/generation/generators/generator-reference/character-scramble.md) 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


Consistency	Yes, can be made self-consistent.
Linking	No, cannot be linked.
Differential privacy	No
Data-free	No
Allowed for primary keys	No
Allowed for unique columns	No
Uses format-preserving encryption (FPE)	No
Privacy ranking	3 if not consistent 4 if consistent
Generator ID (for the API)	`ArrayTextMaskGenerator`

## 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](/app/generation/generators-assign-config/generators-data-encryption-config.md) is enabled, then to use it for this column, in the advanced options section, toggle **Use data encryption process** to the on position. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
