These objects are equal: moving a key does not change its value.
{"a":1,"b":2}{"b":2,"a":1}These arrays differ at indexes 0 and 1: array items are compared by position, not by an ID field.
[1,2][2,1]Compares JSON at every nesting level. Handles deeply nested objects, arrays, strings, numbers, booleans and null values with full path reporting.
Differences are color-coded: green for additions, red for deletions, yellow for modifications. Instantly spot what changed between two JSON documents.
Each difference shows the exact JSON path (e.g., server.db.pool.max) so you know precisely where the change occurred in the structure.
All comparison happens in your browser. Your JSON data never leaves your device — ideal for comparing sensitive API responses or config files.
Yes. Objects with the same keys and values are equal even when their keys appear in a different order. Whitespace outside strings does not affect comparison. Array order and value types still matter: 1 and "1" are different.
The tool parses both JSON inputs and performs a deep recursive comparison. It identifies added keys, removed keys, and modified values at every nesting level, then displays results with color-coded output.
Yes. The comparison is fully recursive and handles deeply nested objects and arrays. Each difference shows the full JSON path (e.g., server.db.pool.max).
Absolutely. All processing happens entirely in your browser using JavaScript. No data is ever sent to any server. You can even use it offline once the page is loaded.
Yes. Arrays are compared element by element (by index). If one array is longer, extra elements are shown as additions or deletions.
