About

NDJSON Payload Parser automatically detects and parses Newline-Delimited JSON (NDJSON) payloads from network request bodies, displaying them in an easy-to-navigate tree structure within Chrome DevTools.

FEATURES:
• Automatic NDJSON detection from request payloads
• Interactive collapsible JSON tree with syntax highlighting
• Smart search with text or regex support
• Filter requests by URL (text or regex)
• Two-tab interface: Request Payload and HTTP Headers
• Material Design UI with resizable panels
• Click-to-copy JSON to clipboard
• Real-time request monitoring

PERFECT FOR:
• Debugging streaming telemetry and analytics
• Analyzing batch API responses
• Inspecting NDJSON-formatted data
• Monitoring application events and metrics

PRIVACY:
• Runs entirely locally in your browser
• No data collection, storage, or transmission
• No external network requests
• No analytics or tracking

The extension adds a dedicated "NDJSON Parser" tab to Chrome DevTools. Open DevTools (F12), navigate to the new tab, and it will automatically capture NDJSON payloads from POST requests.
