The Complete Guide to JSON Patch (RFC 6902)
JSON Patch (RFC 6902) defines a standard format for describing partial updates to JSON documents. Instead of sending entire documents, you send only the changes, making APIs more efficient. Our JSON Patch Generator helps you create and test patch operations.
What Is JSON Patch?
JSON Patch is a format for expressing a sequence of operations to apply to a JSON document. Each operation is an object with an "op" property (add, remove, replace, move, copy, test) and a path pointing to the target location.
JSON Patch Operations
- add — Inserts a value at the specified path
- remove — Removes the value at the specified path
- replace — Replaces the value at the specified path
- move — Moves a value from one path to another
- copy — Copies a value from one path to another
- test — Tests that a value matches at the specified path
How to Generate JSON Patch
Our JSON Patch Generator compares two JSON documents and generates the optimal sequence of patch operations to transform the first into the second. Use our JSON Diff Checker to see the differences first.
Validating JSON Patch
Before applying patches in production, validate them with our JSON Patch Validator. It checks for correct operation syntax, valid JSON Pointer paths, and proper sequencing.
JSON Merge Patch Alternative
For simpler use cases, JSON Merge Patch (RFC 7396) provides a more straightforward approach. Unlike JSON Patch, it uses a partial JSON document to describe changes.
Frequently Asked Questions
What's the difference between JSON Patch and JSON Merge Patch?
JSON Patch uses a sequence of operations for precise control, while JSON Merge Patch uses a partial document that's simpler but less powerful.
Is JSON Patch secure?
Yes. Our tools process everything client-side. No data leaves your browser.
