I’ve used https://github.com/nrkno/Quibble for this recently. Seems to work well. I ended up writing some custom code to sort the JSON properties alphabetically before comparing which seemed to improve results for objects with a larger number of differences More on reddit.com

Yes Firstly you have to load json data in python dictionary using json module/package After that jsondiff module/package help you check different This module/package also compare list,set,etc.👌 If will return empty dictionary {} if there is no different👍 import jsondiff oldJson = {1:"a",2:"b",3:"c"} newJson = {1:1,4:4} r = jsondiff.diff(oldJson,newJson) if r : print(r) else: print("404,No Different Found!") Output: {1: 1, 4: 4, delete: [2, 3]} 😀 json.diff take 1st arg oldJson means from which we are checking different & 2nd newJson. There are 3 syntax 🎲 : compact ( default ) Any Change in Value of key & new insrted key will display normaly symmetric Inserted & delete show differently change show normally explicit 👀 It is detailed Inserted Deleted Changed Show differently import jsondiff oldJson = {1:"a",2:"b",3:"c"} newJson = {1:1,4:4} r = jsondiff.diff(oldJson,newJson,syntax="explicit") if r: print(r) else: print("404,No Different Found!") Output : {insert: {4: 4}, update: {1: 1}, delete: [2, 3]} 😃 Finally 🔥,Now you doubt about how to access them You can access them using symbols eg. r[jsondiff.symbols.insert] OR from jsondiff import symbols r[symbols.insert] There are some other symbols which use in different compare like list,set, etc Note : if you try using insert in compact & update in compact & symmetric then you will get KeyError 😔 because those not exist there import jsondiff from jsondiff import symbols oldJson = {1:"a",2:"b",3:"c"} newJson = {1:1,4:4} r = jsondiff.diff(oldJson,newJson,syntax="explicit") if r: print("Deleted keys are ",r[symbols.delete]) else: print("404,No Different Found!") Output : Deleted keys are [2, 3] 🥳 Thanks for reading 😂 More on reddit.com

Hey everyone, I wanted to share a set of free online JSON tools I've been working on, designed to make your daily dev life a bit easier. We often deal with JSON, and I found myself constantly needing quick ways to:
✅ Validate & Beautify JSON: Check for syntax errors and make unreadable JSON clean and structured.
↔️ Compare JSON: Easily spot the differences between two JSON files. Super handy for API versioning or debugging!
🔀 JSON Difference: Get a clear, highlighted view of what's changed between two JSON payloads. These tools are built to be super fast, private (your data stays in your browser!), and can handle even large JSON payloads without breaking a sweat. Give them a try and let me know what you think! Any feedback is highly appreciated.

r/golang on Reddit: Built a Tool for Deep JSON Comparison - Seeking Input on Array Diff Visualization
July 30, 2024 -
Hey r/golang community,
I've been grappling with a recurring challenge in my work: comparing large, deeply nested JSON files. To tackle this, I created a CLI tool in Go that helps highlight differences between two JSON files with high precision.
The tool is relatively compact, about 200 lines of code, and handles different types of changes well, including additions, deletions, and type mismatches. However, I'm looking to improve how differences within arrays are displayed. Currently, if an item at the beginning of an array is modified or removed, all subsequent items are marked as changed, which isn't very helpful for quick analysis.
Here's where I could use your collective wisdom:
Visualization Techniques: Does anyone have suggestions for more intuitive ways to display array differences? Maybe a method that effectively pinpoints and isolates changes without cascading the entire array?
Code Feedback: I'd love to get some feedback on the implementation. I'm sure there are optimizations and best practices that I could apply to enhance the tool's performance and usability.
I'm looking forward to your insights and suggestions. Let's make JSON comparisons easier for everyone!
You can check out the tool and contribute here: https://github.com/phplego/jcmp
Thank you all in advance!

Look up "diff algorithm". It is a rich field of study with much to learn. I'm not intimately familiar with it personally, but having now struggled with the problem yourself you're in a great position to hit the literature and benefit from it. I'm a big believer in the idea that it is very hard to understand solutions to problems you don't have, but now you've had them.
