Generate and apply RFC 6902 JSON Patch operations for JSON changes.

Generate and apply RFC 6902 JSON Patch operations locally in your browser for API version changes, configuration updates, and data sync workflows.

How to use

Paste the original JSON and the updated JSON to generate add, remove, and replace operations.
Switch to Apply Patch and paste the source JSON plus a Patch array.
Review the output JSON, then copy the Patch or reverse Patch when needed.

JSON and Patch data stay in your current browser.

JSON Patch is the RFC 6902 operation format for describing changes to a JSON document with add, remove, replace, and related operations.

Arrays are compared by index, and appended items use /-. Reordering an array may produce several replace operations.

No. Patch generation, application, and reverse Patch creation run in your current browser.
