The advantage is, it's not limited to structure only and can compare values if you wish: JSONCompareResult result = JSONCompare.compareJSON (json1, json2, JSONCompareMode.STRICT); System.out.println (result.toString ()); which will output something like: Is a downhill scooter lighter than a downhill MTB with same performance?

How to compare two Json objects using C# - Stack Overflow After implementing the parsing functions, I started to exploit the possibility of comparing two IJSONValue instances to show their differences. Simple example code assumes the structure to be exactly the same. When we use equals, it compares all the members recursively, which means nested objects are also comparable: Maven Dependency First, let's add the jackson-databind Maven dependency: <dependency> <groupId> com.fasterxml.jackson.core </groupId> <artifactId> jackson-databind </artifactId> <version> 2.13.3 </version> </dependency> Copy 3. Defines limited JSON classes to enable JSON string processing as outlined in, Parses big JSON text block and saves the contents as, The JSON values can be used as media to compare Java Objects to get their minimum differences as another JSON Object. Should HTTP PUT create a resource if it does not exist. You can find compare related to Missing properties, incorrect types, unequal values. Jackson is one of the most used libraries for comparing JSON objects. Add the following dependency to your pom.xml: Alternatively, you can get the package from Maven Central directly. JSON is actually NOT a string, so above comments are irrelevant. Also in a JSON string, all keys have to be surrounded by quotes (which is not the case in your example). This tool allows to compare two JSON data structures, and visualize the diff . TheISortable getSorted(Comparator) method inherited byIJSONValue wold re-arrange the elements ofJSONObject with desirable orders, and it would also be used by theJSONArray to pass to all its childrenJSONObjects. zjsonpatch may behave different with int and float value comparison (treating 1 and 1.0 different). Just including the FluentAssertions.Json worked fine for me. On the other hand, it is possible to enforce more strict syntax checking by calling IJSONValue parse(boolean isStrictly, CharSequence jsonText) with "isScritly=true" (with a overhead of 1-5%), then the same JSON texts would cause errors thrown: By changing the static variable of Parser.PARSE_STRICTLY to true to turn off the default lenient parsing, calling IJSONValue parse(CharSequence jsonText) would enforce the strict syntax checking automatically.
