patilabhishekramesh/excel-analyzer ? reverse-engineered prompt

Build me an offline Excel and CSV analyzer for confidential student data.

I want to upload XLS, XLSX, or CSV files and have the app figure out the important columns even if the sheet structure is messy or unknown. Then it should generate useful executive summary metrics, a few dashboard views, charts, and exportable results automatically. It should also classify things like institution type, degree type, work experience bands, and score bands from the data.

Keep everything local only. No login, no database, no cloud APIs, and nothing should leave the computer. If a local GGUF model is present in the models folder, use it for short insights, and if not, still make the app work with rule based analysis.

Please make the frontend feel like a clean analytics dashboard, and the backend handle parsing and analysis reliably. If you need to check any current docs for local model support, go ahead and look them up online.
