VSM JSON tree editor#
The tree editor allows you to directly edit the value stream JSON file from the UI.
Use the online tree editor to edit value stream JSON files. Starting with HCL™ Accelerate version 3.0, you no longer need to download the JSON and edit a local copy. Now you can edit value stream JSON files within the product web interface. On the Value Streams page, use the VSM JSON tree editor to edit and save the value stream workflow file. In tree view, the editor allows you to perform the following:
- Change Type, Insert, or Append the Auto, Array, Object, or String field types defined in the following:
- Auto is a field type based on the value of a string, number, boolean, or null.
- Array contains an ordered collection of values.
- Object contains an unordered set of key and value pairs.
- String is a field type not based on the value and returned as a string.
- Duplicate fields
- Extract objects and arrays
- Remove fields
Additionally, you can format, compact, repair JSON data, and save with overwrite protection for simultaneous user editing scenarios.
