⚠️ UNDER MAINTENANCE - This project is still being actively developed. Some features may be incomplete or change without notice.

A web-based tool that converts Claude Code CLI conversation logs (JSONL format) into human-readable Markdown. Features a built-in file explorer for managing multiple logs at once.

🌐 Live Demo: jsonl.withlinda.dev

Claude Code CLI automatically saves all your conversations in JSONL format at ~/.claude/projects/. These logs are difficult to read in their raw form. This tool makes them human-readable by:

• Converting JSONL to formatted Markdown
• Preserving conversation structure and timestamps
• Highlighting model changes and tool usage
• Organizing multiple sessions for easy browsing

1. Visit jsonl.withlinda.dev

2. Locate your Claude Code logs:

   • On Mac: Press Shift+Cmd+G in Finder and type ~/.claude/projects/
   • On Linux/Windows: Navigate to ~/.claude/projects/ in your file manager

   

3. Drag & drop or upload your .jsonl files

4. View, search, and export your conversations

# Clone and install
git clone https://github.com/withLinda/claude-JSONL-browser.git
cd ClaudeJSONLbrowser
npm install

# Start development server
npm run dev
# Open http://localhost:3000

• Multi-file Management: Process multiple conversation logs simultaneously
• Smart Parsing: Automatically extracts session metadata, timestamps, and conversation flow
• Search: Find content across all loaded conversations
• Export Options: Download individual or combined Markdown files
• Tool Use Formatting: Clearly displays when Claude uses tools and their outputs
• Model Change Tracking: Highlights when you switch between Claude models

The tool specifically handles Claude Code CLI log structure:

• Session Metadata: Session ID, Git branch, working directory
• Message Types: User messages, Claude responses, system summaries
• Special Commands: /model changes, tool uses, command outputs
• Timestamps: Preserves all timing information

# Production build
npm run build

• Next.js 15 with TypeScript
• Tailwind CSS (Everforest theme)
• Client-side processing (no data sent to servers)

Claude Code CLI doesn't have a built-in export feature for conversation history. This tool fills that gap, making it easy to:

• Review past conversations
• Share solutions with your team
• Create documentation from Claude interactions
• Analyze your Claude usage patterns
