How to use JSON Patch Applier

Review a data-only patch transaction before using its output. A failed operation returns an error; the source string and external state remain unchanged.

Enter input, json patch array.
Choose the settings for json patch applier, then run the tool.
Review the result and any limitations before copying or downloading it.

Good to know

100 operations, 100,000 characters per input, 10,000 values and depth 40. Root-document removal is explicitly unsupported.
Pointer traversal uses own properties only; prototype-like keys remain ordinary JSON data. Standard numeric precision applies.
Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.

Common questions

What happens if a test operation fails?

The run fails without returning partial success or changing the original source.

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.
