JSON PATH Scraper

JSON PATH Scraper helps you analyze, filter, and transform JSON data using powerful JSONPath expressions. It simplifies working with large JSON documents by extracting only what matters and reshaping it into clean, usable output. Built for developers who want fast, precise JSON data extraction without unnecessary overhead.

Introduction

This project provides a flexible way to query and transform JSON documents using JSONPath and lightweight transformation logic. It solves the problem of handling complex, deeply nested JSON by letting you focus only on relevant fields. It’s ideal for developers, data engineers, and analysts who work with APIs or structured data daily.

Smart JSON Data Processing

• Applies JSONPath expressions to filter complex JSON structures
• Supports transformation functions to reshape extracted results
• Works with remote JSON endpoints or local JSON objects
• Designed for clarity, speed, and predictable output
• Easy to validate JSONPath expressions before execution

Features

Feature	Description
JSONPath Filtering	Extract only the JSON nodes that match your defined conditions.
Data Transformation	Apply transformation logic to reshape extracted fields.
Remote JSON Support	Load and process JSON directly from a URL endpoint.
Selective Fields Output	Return only required properties to reduce payload size.
Validation Ready	Test JSONPath expressions for correctness before use.

Example Output

Example:

[
    {
        "name": "Apple iPhone 13",
        "sku": "5447919661404"
    },
    {
        "name": "Apple iPhone 11",
        "sku": "5679549432792"
    }

FAQs

Can this tool handle deeply nested JSON structures? Yes, JSON PATH Scraper is designed to work with deeply nested objects and arrays using standard JSONPath syntax.

Do I need to write complex code to transform data? No, transformations are handled with simple, readable functions that focus only on the fields you need.

Does it support large JSON files? It performs well with large JSON documents, especially when using selective JSONPath filters to limit processing.

Is the output schema fixed? No, the output is entirely driven by your transformation logic, giving you full control over structure and fields.
