Inner Data Format

The tool represents differences in dictionaries accumulated in a list. Here's an example:

[{
    "key": "common",
    "status": "nested",
    "children": [{
        "key": "follow",
        "status": "added",
        "values": false
    }, {
        "key": "setting1",
        "status": "unchanged",
        "values": "Value 1"
    }, {
        "key": "setting2",
        "status": "removed",
        "values": 200
    }, {
        "key": "setting3",
        "status": "updated",
        "old_value": true,
        "new_value": {
            "key": "value"
        }
    }]
}]

Here:

• the key is a name of an object originating from source files,
• values are contents of plain objects and children are contents of nested objects,
• unchanged type of updated nested objects indicated with nested status,.
