À propos de la Boîte à Outils JSON

The JSON Processing Toolkit is a comprehensive suite of utilities designed for modern web developers, API engineers, and data analysts. JSON (JavaScript Object Notation) has become the de-facto standard for data exchange on the web, but manually reading, comparing, or validating widely nested JSON structures can be tedious and error-prone.

This toolkit runs entirely in your browser using client-side JavaScript. This ensures unmatched speed and privacy—your sensitive API keys, configuration files, and customer data are never sent to our servers. You can even use this tool offline once the page is loaded.

We've combined five essential tools into one interface: a semantic Diff Checker for identifying API changes, a Schema Validator for ensuring data integrity, a JSONPath Tester for debugging extraction logic, a Key Sorter for canonicalization, and a Flattener for converting complex objects into simpler formats key-value pairs.

Fonctionnalités Clés

Semantic Diff: Compare two JSON files to see exactly what changed (Added, Removed, Modified). Ignores insignificant whitespace and ordering differences.
Schema Validation: strict validation against JSON Schema (Draft 07/2019-09) to ensure your API responses or config files meet the required specification.
JSONPath Querying: Test and debug complex JSONPath expressions to extract specific nodes from large datasets without writing code.
Canonical Sorting: deterministic sorting of object keys (recursively) to ensure identical JSONs always have the same hash signature.
Structural Transformation: 'Flatten' deep JSON objects into a single level of key-value pairs (great for CSV export) or 'Unflatten' dot-notation keys back into objects.

Cas d'Utilisation Courants

API Regression Testing: Instantly compare the JSON response of your staging API against production to spot unintended changes.
Configuration Management: Sort keys in your `package.json` or config files to keep them organized and reduce merge conflicts.
Data Extraction: Use JSONPath to filter out specific users, products, or logs from a massive JSON dump for quick analysis.
Database Prep: Flatten nested MongoDB documents into a flat format suitable for importing into SQL tables or Excel.
Contract Testing: Validate that your mocks or actual service responses strictly adhere to the agreed-upon JSON Schema.

Référence de Syntaxe JSON

JSON (JavaScript Object Notation) is strict about syntax. Common rules include:

  • Keys: Must always be enclosed in double quotes (e.g., `"name"`).
  • Strings: Must use double quotes. Single quotes are not valid JSON.
  • Booleans: Use lowercase `true` or `false`.
  • Last Element: Trailing commas are forbidden in standard JSON.
  • Null: Use `null` for empty values.
  • No Comments: Standard JSON does not support comments (`//` or `/* */`).

Valid JSON Example

  "project": "CoderTools",
