How to use

Select Load example to restore the sample, or replace the labeled inputs with your own values.
Review the options and select Run tool. No input is sent to a server.
Generate gives an ordered patch. Apply validates and returns the patched document without modifying the input. For Apply, the second input must be a patch array, for example [{"op":"replace","path":"/score","value":2}], rather than the target document.
Inspect the result, then copy or download it. Clear removes visible inputs and output.

A worked example

Load example restores these values.

Operation:
Generate

Original JSON:
{"name":"Ada","score":1}

Target JSON or patch array:
{"name":"Ada","score":2}

Expected result

A replace operation at /score changes the value to 2. Applying that operation returns the target document.

Scope & limitations

Patch paths must exist as required by each operation. Prototype mutation paths are rejected. Operation order matters. JSON numbers use JavaScript binary64 precision; keep large exact identifiers as strings. Numeric overflow is rejected.
