Claude Code History Viewer is a free browser-based tool that lets you browse, search, and export Claude Code conversation history stored in JSONL format. Simply drag and drop your .jsonl files or select your project folder. The tool parses everything locally in your browser — your data never leaves your device. It provides a clean interface with sidebar session navigation, message filtering, keyword search with highlighting, and multi-format export.
Claude Code stores conversation history as .jsonl files in the ~/.claude/projects/ directory on your computer. Each project you've worked on has a separate subdirectory containing one or more .jsonl files with timestamps. You can import individual files or select the entire projects folder to load all conversations at once. The tool supports both single file and batch folder import through the file picker or drag-and-drop.
The viewer supports JSONL (JSON Lines) format files generated by Claude Code. In this format, each line is an independent JSON object containing the message type (user, assistant, tool), content, timestamp, session ID, and working directory. The tool automatically parses these fields to reconstruct conversations with proper categorization of user messages, AI responses, thinking processes, and tool calls.
Yes. The viewer provides three export formats: Markdown (.md) for readable documentation with headers and formatting, JSON for programmatic use and data analysis, and plain text for simple archival. Select a conversation session, click the Export button, and choose your preferred format. Each export includes the conversation summary, project path, timestamp, message count, and all content with role attribution.
