## Description

An embedded HAR/JSON viewer is a tool designed to visualize HTTP Archive (HAR) files, whether they are opened locally or accessed online. This viewer typically provides multiple viewing options, including:

HAR View: Displays the content of the HAR file, allowing users to see details related to HTTP requests and responses, such as headers, timings, and more.

JSON Tree View: Presents a structured tree view of the JSON data contained in the HAR file. This allows users to navigate through the data in a hierarchical format.

Plain (Original) View: Shows the original content of the HAR file without any additional formatting or visualization. This view is useful for users who prefer the raw data.

The viewer aims to enhance the user experience when working with HAR files, making it easier to analyze and understand the information related to web requests and responses. Users can seamlessly switch between different views based on their preferences and the type of analysis they are conducting. Additionally, features such as online access, local file opening, and flexibility in data representation contribute to the effectiveness of the tool.
