An open-source, client-side solution for digitally archiving and analyzing your Costco in-warehouse receipt data.

This project is divided into two interdependent components:

• Receipt Downloader A client-side JavaScript utility designed to extract and archive your Costco in-warehouse receipts, saving the raw data in a standardized JSON format file.

• Receipt Dashboard A client-side web application built for visualizing, searching, and conducting detailed analysis on the receipt data generated by the Receipt Downloader.

The project is designed to run entirely on the client-side, making deployment and use straightforward.

1. Clone the Repository: Download or clone the entire project structure from the main repository.
2. Access the Downloader: Once you've logged in to Costco and accessed the Orders & Returns page, open the Downloader/costco_receipt_downloader.js file and execute its logic within your browser's developer console.
   • For detailed, step-by-step instructions please refer to the Receipt Downloader README.
3. Use the Dashboard: Once you have saved your Costco receipt data, simply open the Dashboard/Dashboard.html file in your browser, load your receipt data file, then visualize and analyze your data.
   • For detailed instructions please refer to the Receipt Dashboard README.

Both components are built on simple, widely-supported web technologies, requiring no server-side environment or external dependencies for the core functionality.

• Front-end & Logic: Vanilla JavaScript
• Structure: HTML5
• Styling: CSS3
• Data Format: JSON (JavaScript Object Notation)

This project leverages the browser's built-in capabilities, ensuring portability and minimal setup. This means you can load it on a portable Drive and/or a mobile device!
