Text Processing provides set and get actions, which you can use to create, modify, or retrieve properties from JSON or YAML content.
The YAML actions support multi-document YAML files through an optional document index parameter.
You can combine the Text Processing actions with other Connector actions, for example, with GitHub Connector action or GitLab Connector action to fetch JSON or YAML files from a repository/project, manipulate them with the Text Processing Connector actions, and update them via a pull request or merge request.
