I currently use a large Excel workbook—about twenty separate screens of tables and input fields—to collect and review data. I now need the same workflow rebuilt as a browser-based template program so anyone with the link can sign in and work online. For data storage, I selected “web,” so I’m open to the stack you recommend as long as it is reliable, scalable, and lets me retrieve records quickly. The finished application should include: • User authentication to control access • Data export options so I can pull information out whenever needed • Real-time data updates so multiple users see changes instantly A key requirement is a reporting tool that lets the user choose filters and instantly download the results in Excel format. What I expect to receive: 1. A responsive web interface divided into roughly 20 screens that mirror the look and logic of the original spreadsheet. 2. A back-end configured with the chosen “web” data store plus a simple admin panel. 3. A filterable report generator that exports directly to Excel. 4. Deployment instructions and brief documentation so I can maintain and extend the solution after delivery. Experience converting complex spreadsheets into web applications is highly valued. Please share your proposed tech stack, timeline, and any clarifying questions you may have.
