JSON Validation & Processing Pipeline

A backend processing pipeline built using Python to clean, validate, transform, and standardize structured JSON datasets through automated preprocessing and validation mechanisms.

---

Overview

This project focuses on building a modular backend processing system capable of handling structured JSON input data efficiently. The pipeline performs validation, preprocessing, transformation, and exception handling to improve data consistency and operational reliability.

The system is designed to simulate real-world backend data-processing operations commonly used in automation platforms, ETL workflows, and structured data-processing systems.
