How to compare 2 JSON files with the same content but in a different order?
As you can see, both JSON files have the same content but in a different order. I would like to compare them with WINMERGE but prior the comparison I would like to reorganize the 2nd JSON to be in the same order that the 1st JSON file, so there will be no difference detected between them.

January 3, 2024What is the best tool for comparing two large json files?
It depends. I would probably write a simple script, assuming every entry has an ID and you just want to track new and removed entries, that would be really simple. Write every ID of JSON1 into a hashmap and test for every ID from JSON2 if that Id appears in the hashmap or not. Preferably in a fast language, like rust, because of the large input and pythons bad loop performance. More on reddit.com

February 18, 2021 - For the second point, I actually define the ordering of exporting of arrays explicitly, so I would expect a like for like compare. For other cases, additional logic would need to be added, as you pointed out · For the last point, this should return a mismatch, which is good enough for my use case, but again, might not be ideal for other use cases ... I guess the 2025 answer is to look at Python solution(s) which are likely many. A quick internet search suggests e.g. https://pypi.org/project/jsondiff/ that seems to be a reasonable complete, recent and popular.

r/learnprogramming on Reddit: What is the best tool for comparing two large json files?
October 7, 2025 -
I have two json files that contain the output of an api call to a report in our property management software from two different days. I want to see which items were added to and removed from the second file compared to the first. each file is about 100,000 lines. I tried using diff, and that does work, but It's really hard to read, given the large number of differences. Is their a better or easier tool for this?

Sounds like you want a "structural diff" tool which finds differences based on the nested structure of the JSON objects themselves, not the serialized text representation. For instance: https://github.com/andreyvit/json-diff You could also hack something together with a JSON manipulation tool such as jq . There are a lot of possibilities depending on what kind of differences you're looking for. For instance, you could transform each file into a list of nested "key paths" (e.g. {"a": {"b": "foo"}} becomes something like a.b: "foo") and then sort and diff those lists instead of the original files.
