LeetCode History Exporter EN

LeetCode History Exporter is a specialized browser extension designed to provide programmers and software engineers with a straightforward and efficient way to export their LeetCode submission history. This tool offers a modern, user-friendly popup interface that empowers users to quickly extract their entire "Practice History" directly from the LeetCode website and save it in a clean, well-structured JSON format. The extension prioritizes customization, allowing users to select which specific submission details they wish to include—such as problem titles, difficulty levels, URLs, timestamps, and more—and to reorder these fields to better suit their personal workflow or the requirements of reports, analytics, study materials, or personal logs.

The extension eliminates the need for complex manual scraping or cumbersome multi-step export processes. Instead, it performs automatic background scanning of LeetCode’s submission tables, seamlessly managing navigation through multiple pages, waiting for data to load fully, and compiling all relevant results into a single dataset. This process is interactive and user-friendly: users receive real-time progress updates within the popup, along with soft error handling that addresses common issues, ensuring that exported data is both reliable and tailored to specific preferences.

Users can fine-tune the JSON output via a configuration panel embedded in the popup interface. This flexibility means that whether a user wants a comprehensive backup of all their submissions or desires a focused archive containing only select details (useful for monitoring progress, sharing with mentors, or migrating data to other platforms), this extension adapts effortlessly. The drag-and-drop functionality for field ordering offers an intuitive way to customize output without any technical background.

Privacy is a core consideration in the design of LeetCode History Exporter. The extension exclusively operates within the leetcode.com domain, and it never transmits any data externally. All exported data is downloaded directly to the user's device, ensuring complete control over personal information. Additionally, user preferences for export configurations are locally stored in the browser, allowing for convenient reuse and minimal setup time during future sessions. The interface includes clear status indicators and safe controls to pause or stop any ongoing export process promptly.

Ideal for students, professional developers, and educators alike, LeetCode History Exporter simplifies the task of saving submission histories. This makes it an excellent tool for personal study tracking, code review, creating educational flashcards, or compiling a portfolio of solved problems for resumes and interviews. It is lightweight, minimally intrusive, and designed for immediate use without requiring technical know-how.
