How comparison works and its limits
Object key order is ignored. Arrays are compared by index, so reordering is reported as changed values. Paths follow JSON Pointer escaping; an empty path means the document root. Each input is limited to 200,000 characters, nesting to 100 levels and the report to 2,000 changes. Both documents must be valid JSON.
Numbers use JavaScript precision. For large identifiers, use quoted strings to avoid rounding. Duplicate object keys follow JSON.parse behavior: only the last value is kept. This is not a schema validator or a security audit. Review the report before changing production data.
Privacy: inputs are not uploaded, stored in browser storage or sent to an AI service. A hosted copy only retrieves public payment instructions from this site. The offline copy makes no network requests. Clear inputs when finished on a shared device.
