File Previewer

Preview CSV, NPY, ZIP files directly in your GitHub side panel without any external tools & file download, along with theme support

This extension is designed to solve the "download hassle" by allowing you to inspect complex data and compressed archives directly within the GitHub interface. By using a powerful preview engine in your side panel, it eliminates the need to constantly download, extract, and open files in external software just to verify their contents. What the extension does Numpy (.npy) Inspection: It provides an instant view of array data, including dtype and shape metadata, and allows for the conversion of these files into text or JSON formats. ZIP Archive Exploration: It features a VS Code-like nested file explorer that lets you browse inside .zip files without downloading them. Selective Access: You can view the size of individual files and folders within a ZIP and choose to download or preview only the specific items you need. Data Conversion: It converts CSV files into clean JSON previews and allows for quick "on the fly" exports. UI Integration: The tool blends into GitHub's native UI and supports Dark, Light, and System modes to match your environment. Why you should install it Save Time and Bandwidth: You no longer need to download large archives or data files only to realize they weren't the ones you were looking for. Streamlined Workflow: By keeping everything inside the GitHub tab, it prevents the disruption of switching between your browser, terminal, and local file explorer. Instant Visibility: It acts as "X-ray glasses" for GitHub, giving you immediate visibility into raw data formats like .npy that GitHub natively displays as "View Raw". Local Privacy: All parsing and processing happen locally in your browser’s memory, ensuring your data never leaves your machine. Efficient File Management: The size-tracking feature for folders and files within ZIPs helps you manage local storage by avoiding unnecessary bulk downloads.
