Build and inspect JSONPatch changes

JSONPatch Builder and Debugger for Windows

Create an ordered JSONPatch array beside the active JSON document, apply operations one at a time, inspect each result, and keep the final document only when the patch behaves as intended.

Structured patch authoring

Build JSONPatch operations with less manual typing

It works with standard JSONPatch array documents and keeps the operation list beside the JSON data being changed. Authors can load, save, add, delete, edit, and reorder operations without hiding their sequence.

Choose the operation

Work with ordered operations such as add, remove, replace, move, copy, and test. Each row exposes only the fields needed for that operation.

Set paths and values deliberately

Edit path, from, and JSON value content while keeping JSON Pointer syntax and the active document structure visible.

Control execution order

Move operations up or down before running the patch. Order matters because a later path can depend on an object, array item, or value created or moved by an earlier operation.

Debugger-style execution

Step through JSONPatch changes and see where behavior diverges

The workflow applies operations from top to bottom and exposes controls for moving through the list at different speeds. Use the step controls to inspect the patch result at each operation.

Move through the patch

Reset returns to the session start, Step Next applies the next operation, and Step Back returns to the previous patch state.

Run to the point you need

Run To applies operations through a selected row, while Apply All processes the remaining list. Accept keeps the current patched result when it has been reviewed.

Stop on a useful failure

The documented pane marks operation status, identifies the next row, stops at the first failed operation, and moves the editor selection to the related patch position where possible.

Editor-aware helpers

Use the active JSON selection instead of retyping every pointer

A hand-written JSON Pointer is precise but easy to mistype. The pane can take the selected JSON value’s pointer for path or from, and it can use selected JSON text or a selected value as the operation’s value.

  1. Select the relevant value in the active JSON document.
  2. Use the pane helper to fill the path, source path, or value.
  3. Review the generated operation and place it in the intended order.
  4. Step through the patch, inspect each document update, and accept only the verified result.
Selection helps do not remove review

Confirm pointer escaping, array indexes, move/copy source behavior, test values, and the effect of earlier operations. A helper reduces transcription work; it does not prove that the patch expresses the intended change.

Session safeguards

Keep patch state and document state synchronized

Pane-driven undo and redo checkpoints are refreshed during legitimate stepping, while operation edits, reordering, loading, reset, acceptance, and failed execution update the session state.

A distinct workflow

Keep interactive patch debugging separate from generated validation fixes

This pane is documented for JSONBuddy’s interactive Windows editor. It does not replace the Results-pane workflow for schema-validation fixes and is not presented as an XML ValidatorBuddy feature. Keeping those paths distinct prevents a generated correction from being confused with a hand-authored JSONPatch session.
