Frequently Asked Questions
Does this tool use JSON Pointer paths correctly?
Yes. Patch paths follow RFC 6901 pointer escaping rules, including ~0 for tilde and ~1 for slash in key names.
Can I generate patches for large JSON payloads?
Yes. Large inputs automatically use a Web Worker with progress and cancel support to avoid blocking the UI.
Is my JSON uploaded to a server?
No. All processing happens locally in your browser. No data is uploaded or stored.
