What is JSON Merge Patch?

JSON Merge Patch is a standardized method for partially updating JSON documents, defined in RFC 7396. It provides a simple way to describe changes to a JSON document, making it ideal for API interactions and data synchronization tasks. Learn more

How JSON Merge Patch Works

  • The patch is a JSON document itself, describing the changes to be made to the target document.
  • Properties in the patch replace corresponding properties in the target.
  • A null value in the patch removes the property from the target.
  • Properties not mentioned in the patch remain unchanged in the target.
