How to use JSON Merge Patch Workbench

Use null deletion and atomic array replacement deliberately. Drafted patches are reapplied and checked before export so an unrepresentable target is refused.

  1. Enter input, patch or desired target.
  2. Choose the settings for json merge patch workbench, then run the tool.
  3. Review the result and any limitations before copying or downloading it.

Good to know

  • 100,000 characters per document,10,000 values and40 levels. Arrays replace as a whole; null in an object deletes a property.
  • Draft cannot represent every null-valued object addition. No remote references or original-document mutation.
  • Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.

Common questions

Is this a JSON Patch operation list?

No. RFC7396 uses an object-shaped document; RFC6902 JSON Patch uses explicit operations and can express additional distinctions.

Is this input sent to a server?

No. The application processes this input inside your browser tab and does not save it to persistent storage.
