# substitute_string
|
|
|
|
The `substitute_string` processor matches a key's value against a regular expression and replaces all matches with a replacement string. `substitute_string` is a [mutate string](https://github.com/opensearch-project/data-prepper/tree/main/data-prepper-plugins/mutate-string-processors#mutate-string-processors) processor.
|
