shuffle-json-data

Overview

A GitHub Copilot skill that safely shuffles repetitive JSON objects by validating schema consistency before randomizing entries. Acting as a data engineer, it validates that all objects share identical property names, rejects files with nested objects or inconsistent structures in its default mode, and only proceeds after confirmation that the data can be shuffled without corruption.

Key Features

• Pre-shuffle validation: Enforces a strict data validation checklist — verifying identical property names across objects, no nested objects (in default mode), and syntactically valid JSON — stopping and reporting inconsistencies instead of producing corrupted output.
• Safe default behavior: In its default state, shuffles at the object level only when all objects share the same flat structure, rejecting nested objects and inconsistent schemas to prevent data integrity issues.
• Variable overrides for flexibility: Supports ignoreProperties, requiredProperties, and nesting override variables that relax default constraints, allowing shuffling of more complex JSON structures when the user explicitly configures how to handle them.
• Structured workflow: Follows a five-step process — gather input, review configuration, validate structure, shuffle data, and return results — preserving the original encoding and formatting conventions throughout.

Who is this for?

This skill is designed for data engineers, QA testers, and developers who need to randomize the order of JSON array entries without breaking data integrity. It is especially useful for shuffling test datasets, anonymizing data ordering for bias testing, creating varied sample data from templated JSON, or any scenario where safe, validated JSON reordering is required.
