AIS/TIS PDF to Excel Tool

I need a small, web-based utility that lets me upload Indian Income-tax AIS or TIS PDFs, enter the document password (format: pan+ddmmyyyy, always lowercase), and instantly receive an Excel file that mirrors every table exactly as it appears in the source.

Interface
I am aiming for a simple, clean screen: one upload field, one password field, and a “Convert” button. No dashboards or extra clutter—just a lightweight page that works on any modern browser.

Core workflow
• User selects the AIS/TIS PDF.
• User types the password in small letter and password combination is PAN NO+DDMMYYYY.
• The app decrypts, parses each table, and writes them into an .xlsx workbook “as-is”.
• An additional worksheet called “Summary” is auto-generated in strictly tabular form.

Summary worksheet must show:
• Total income calculated
• Tax deductions overview
• Yearly income comparison
• TDS section-wise details
• Date-wise list of every transaction
• A consolidated summary of all transactions

Technical notes
The parsing must cope with typical AIS/TIS layouts, column headers, and multi-page tables without dropping rows or misaligning numbers. I am fine with Python (pdfplumber, camelot, pandas, flask), Node, or any stack you prefer, provided the final deliverable is:
1. Source code with brief setup instructions
2. A running demo link or dockerised build I can test
3. Cleanly formatted Excel output that matches the PDF and includes the extra summary sheet

Acceptance
I will verify by uploading several sample PDFs; the Excel version must replicate every column and value and show the summary exactly as listed above.
