JSON Diff

A free online text processing tool that compare two json 对象并高亮差异. Transform, analyze, and manipulate text instantly in your browser. When API responses change between deployments or configuration files drift across environments, identifying the exact structural difference between two JSON documents is critical for debugging. Nested objects, reordered arrays, and added or removed keys are easy to miss when scanning raw text. A purpose-built JSON diff tool recursively compares both structures and surfaces every discrepancy with a clear path notation. The comparison performs a deep structural diff that traverses nested objects and arrays, highlighting added keys, removed keys, and changed values with their old and new content. JSONPath notation pinpoints exactly where each difference lives. Paste your original JSON in the left pane and the modified JSON in the right pane. Added, removed, and changed keys and values are highlighted side by side instantly. All comparison happens locally. Your JSON data never leaves your browser — safe for comparing API responses, config files, and sensitive payloads.
