Panels
The application contains two panels: a code editor on the left, and a Tree Editor on the right.
There is a splitter between the two panels, allowing to change the width of both panels according to ones needs. To copy the contents from one panel to an other, the two copy buttons between the panels can be used.

The menu of the code editor contains the following buttons:
- Format. Format the JSON data, make the data readable by applying indentation and returns.
- Compact. Compact the JSON data, remove all unnecessary characters like whitespaces and returns.

- Expand all. Expand all fields in the editor.
- Collapse all. Collapse all fields in the editor.

The field values in the editor are editable input fields.
The fields can be dragged up and down using the dragarea
on the left side of the fields. When a field is the last item of the
childs of an array or object, the field can also be dragged horizontally
to move it in or out of the array or object.
Right from the dragarea is a button
to open the actions menu.
Depending on the type of field, the following functionality is
available in the actions menu:
-
Type. Change the type of the field. Choose from:
- auto The field type is automatically determined from the value and can be a string, number, boolean, or null.
- object An unordered set of key/value pairs.
- array An ordered collection of values.
- string Field type is not determined from the value, but always returned as string.
- Sort. Sort the childs of an array or object. For an array, the values of the childs will be sorted. In case of an object, the childs will be sorted by key. Arrays and objects can be sorted ascending or descending.
- Insert. Insert a new field before current field. Available types are auto (default), object, array, and string.
- Append. Insert a new field after current field. Available types are the same as the insert action.
