Describe a change as ordered operations

A JSONPatch document is an array whose operations run in sequence. This example copies the first item under baz to a new property named boo:

[
              { "op": "copy", "from": "/baz/0", "path": "/boo" }
              ]

Applied to { "baz": [{ "qux": "hello" }], "bar": 1 }, the result retains the existing data and adds "boo": { "qux": "hello" }. Validate the patched result after applying the required operations.

Apply a patch to selected files

  1. Select one or more JSON data files in JSONBuddy's built-in File Explorer.
  2. Open the context menu and choose the documented Apply JSONPatch operations command.
  3. Select the JSONPatch array in the standard Windows file dialog.
  4. Inspect each output, confirm the target files and naming behavior, then validate the patched JSON.

Move repeatable patches to the Windows command line

Verify more than well-formedness

  • Review operation order because later paths can depend on earlier changes.
  • Compare the patched data with the intended result, including arrays and escaped values.
  • Run JSON Schema validation when the output must satisfy a contract.
  • Retain the source or use version control until the result has been accepted.

Build and debug the patch interactively

Use the JSONPatch Builder and Debugger to author and step through operations, or return to JSON formatting when the required change is presentation-only.
