Generate JSON Patch

Each document is capped at 512 KiB; combined input is capped at 1 MiB.

Tool Swim does not upload, fetch, save, log, or create presets from these values.

RFC 6902 patch

The report states the algorithm, semantics, paths, counts, or conflicts used as proof.

What this tool proves

Explicit, bounded structural semantics

The generated operation array uses escaped JSON Pointer paths and is intended to be applied in order. Generation does not add test operations or claim a minimal edit sequence.

Patch order is significant

The generated operation array uses escaped JSON Pointer paths and is intended to be applied in order. Generation does not add test operations or claim a minimal edit sequence.

Each document is capped at 512 KiB, combined input at 1 MiB, traversal at 100,000 values and 100 levels, reports at 10,000 entries, and output at 1 MiB. Source and results stay in the active browser tab.

Parsing and comparison semantics

Inputs use the browser's JSON parser. Duplicate object names therefore keep their last value, object member order is ignored, array order is preserved unless the selected tool explicitly says otherwise, and integers outside JavaScript's safe range are rejected instead of rounded silently.
