# Document Properties: Scrambling
This tab is only available when working with a QlikView document in ADMIN mode. It provides the possibility to scramble the data in one or more fields.

| Fields | This is a list of all fields in the document. Select one or more fields
for scrambling. |
| Scramble | Press this button to perform a random scrambling of the contents of
selected field(s). Numbers are scrambled to numbers and text to text (spaces
are kept). Once scrambled, the data cannot be recreated in its original
form by Qlik or anyone else. If the script is re-executed, however,
the scrambling will be lost. |
