Hope this will help you.

Logic.

• Loop through the array of object and pick individual objects.
• Loop through the keys of that specific object.
• Check whether there is a dot or a space in that key. If there is a dor or space, format that key string as per the requirement, and aassign the value of the old key to that new one.
• Delete the node with dot or space from the object and add the new formated key with the old value.
