 # Gsub processor
 
-The `gsub` processor performs a regular expression search-and-replace operation on string fields in incoming documents. If the field contains an array of strings, the operation is applied to all elements in the array. However, if the field contains non-string values, the processor throws an exception. Uses cases for the `gsub` processor include removing sensitive information from log messages or user-generated content, normalizing data formats or conventions (for example, converting date formats, removing special characters), and extracting or transforming substrings from field values for further processing or analysis.
