Connecting MemonaIQ servicesCompare JSON and XML API responses and understand exactly what changed—without digging through thousands of lines.
Built for API debugging
Property order and indentation should not hide a changed type three levels down. MemonaIQ parses each payload into a safe structural model, compares it deterministically, and gives every difference a precise path.
JSON property order and formatting do not create differences.
Search, filter, and copy paths such as /users/0/profile/email.
See number → string, null → object, and array → object changes clearly.
Choose original or modified values without copying fields manually.
Removed fields and type changes receive cautious, deterministic warnings.
Payloads stay in memory in your browser and are never persisted automatically.
Compare expected and actual responses, then filter directly to type or field changes.
Ignore request IDs and timestamps while keeping meaningful environment differences visible.
Review removed fields, changed nesting, and potential compatibility issues before migrating consumers.
Understand how a vendor response evolved without sharing confidential payloads with another service.
Add JSON or XML to Original and Modified.
MemonaIQ detects the format and reports useful parser locations.
A Web Worker parses, normalizes, matches arrays, and builds the diff model.
Use focused views, ignore noise, merge values, or export an RFC 6902 patch.
A semantic diff compares parsed values and structure, so whitespace, indentation, and object-property order do not create false differences.
No. Ordinary comparison, formatting, merging, and patch generation run locally in your browser. Payload contents are not sent to MemonaIQ or analytics.
Yes. The comparator traverses nested objects and arrays, exposes JSON Pointer-style paths, and can match object-array items using stable identifiers when it can do so confidently.
Yes. XML elements, attributes, text values, repeated elements, and nesting are compared structurally. DTD and entity declarations are rejected and external entities are never resolved.
No. Null, false, zero, an empty string, and a missing property remain distinct by default.
Yes. Each difference can use the original or modified value in a separate merged working copy. Inputs are never silently mutated, and merge choices can be undone or reset.
JSON Patch is the RFC 6902 format for describing add, remove, replace, and move operations that transform one JSON document into another.
The current safety limit is 5 MB per payload, 100 nesting levels, and 100,000 parsed nodes. Large comparisons run in a Web Worker to keep the page responsive.
