HyperTest JSON Diff
Why Use HyperTest?
Structural vs Textual Diff
Standard diff tools treat JSON as text. If keys are reordered, they report a change. HyperTest treats JSON as a logical structure, ignoring order but catching missing properties, type changes, and nested value mismatches.
Exact Path Identification
HyperTest provides a programmable path (e.g., root.users[0].email) for every difference. This allows developers to immediately identify which object in a complex API response needs attention.
Local & Private
Your JSON data is parsed entirely in your browser. Sensitive API responses or config files never leave your machine, ensuring 100% compliance with data privacy standards.
Frequently Asked Questions
What is a Representation mismatch?
This occurs when the same value is represented by different types (e.g., "123" string vs 123 number). In many languages, this leads to runtime errors, so HyperTest flags it specifically.
How deep can HyperTest compare?
The algorithm is recursive and handles arbitrary levels of nesting. We recommend files under 10MB for the smoothest browser experience.
