JSON Patch Generator — create RFC 6902 patch documents from JSON diffs

RFC 6902 JSON Patch is a standard format for expressing a sequence of operations to apply to a JSON document. Each operation is an object with an op field (add, remove, replace, move,copy, or test), a path using JSON Pointer notation, and optionally a value. JSON Patch is used in REST APIs (PATCH requests), version control systems for JSON data, and anywhere a minimal diff representation is needed. This tool generates the minimal set of add, remove, and replace operations by recursively comparing two JSON documents.
