Json compare arrays5/3/2023 For the task at hand, the version using keys should be used. Lets read the input JSON as JsonNode and compare: assertEquals(mapper.readTree(s1), mapper.readTree(s2)) Its important to know that two list elements are only compared as equal if they have the same values in the exact same order. JSON. Methods to compare two arrays in Javascript are: Equality comparison: Using the or operators. POST-POSTSCRIPT: The builtin version of walk has recently been changed so that it no longer sorts the keys within an object. Comparing two arrays in Javascript means checking whether both the arrays contain the same number of elements or not, and whether all those elements have the same value or not. $JQ -r -n -argfile A "$1" -argfile B "$2" -f 1.5, and can therefore be omitted if your jq includes it, but there is no harm in including it redundantly in a jq script. ( )Īnd wrapped up as a bash script: #!/bin/bash You can also beautify JSON or formate JSON. Here is a solution using the generic function walk/1: # Apply f to composite entities recursively, and to atoms JSON Compare has the functionality to find different with JSON APIs, JSON Files and JSON Data. r def post_recurse: post_recurse(.?) ($a | (post_recurse | arrays) |= sort) as $a | ($b | (post_recurse | arrays) |= sort) as $b | $a = $b' Arrays and objects are checked for deep equality. r def post_recurse: post_recurse(.?) (post_recurse | arrays) |= sortĪpplied to the jq invocation above: jq -argfile a a.json -argfile b b.json -n 'def post_recurse(f): def r: (f | select(. The equality operator returns Boolean true if both operands are the same (type and value). It helps to find the different between two json to find the accurate results. This GitHub issue explains why and provides some alternatives, such as: def post_recurse(f): def r: (f | select(. JSON Compare tool to compare two JSON data with ease. Use the Parse JSON step to iterate the first array and use the filter array to check whether it exists or not. | arrays) |= sort construct doesn't actually work as expected on some edge cases. Returns a dynamic (JSON) array of the set of all distinct values that are in the first array but arent in other arrays - ( ( (arr1 arr2) arr3). This program should return "true" or "false" depending on whether or not the objects are equal using the definition of equality you ask for.ĮDIT: The (. We will cover two of them: JSON.stringify() Comparing with JSON.stringify() may not work for more. Assuming your two files are named a.json and b.json, on the latest jq nightly: jq -argfile a a.json -argfile b b.json -n '($a | (. There are several ways to compare two arrays in JavaScript. Since jq's comparison already compares objects without taking into account key ordering, all that's left is to sort all lists inside the object before comparing them.
