NDJSON Payload Parser is a Chrome extension designed to enhance the development experience by efficiently parsing Newline-Delimited JSON (NDJSON) payloads directly within Chrome DevTools. This tool automatically detects NDJSON from network request bodies, presenting the data in an interactive, collapsible tree structure that supports syntax highlighting. Developers can easily navigate through complex payloads with features such as smart search, allowing both text and regex queries, and filtering requests by URL.

The extension features a user-friendly Material Design interface with two tabs for Request Payload and HTTP Headers, enabling a seamless workflow. Users can monitor requests in real-time, copy JSON data to the clipboard with a single click, and utilize resizable panels for enhanced usability. With a focus on privacy, NDJSON Payload Parser operates entirely within the browser, ensuring no data collection or external network requests.
