How can I compare two JSON objects and return new JSON object with only the changes and if there is empty data in the OldData in a key then it will show the data of newData see the example below: Here, we will see a Python program to compare two objects using a comparison operator. In the following script, the same array of JSON objects has used that was used in the previous example. name : "test 2", }; To perform the diff, we simply need to call the diff method on the DiffPatcher object, passing as first input the first object and as second input the second object. deepEqual will instead check for reference equality between a function and its counterpart in the other object. It means that a script (executable) file which is made of text in a programming language, is used to store and transfer the data. This is a simple python script to compare two text files line by line and output only the lines that are different. so requirement is to loop all columns and then compare and write to json.
