Decode Encrypted XLSM Stock Feeder

I’m working with a macro-enabled Excel workbook that arrives fully obfuscated. Inside the .xlsm sits Python code that contacts my broker’s through enc module / API and streams live stock prices exclusively for NSE symbols. Because the source is wrapped in an encrypted file i cannot edit or add macro to it.

Your task is to open up that protection, surface the underlying Python/VBA, and leave me with a readable, editable solution that still performs exactly as it does now—continuous NSE variables updates into the same Excel front-end. The finished file must stay in .xlsm format so all my existing dashboards keep functioning.

Deliverables
• Unlocked .xlsm containing clean, well-commented Python (xlwings / win32com) or VBA modules
• A brief note explaining any dependencies, API keys, or library versions required to keep the live feed running
• Confirmation that real-time NSE prices and other variables populate the sheet after your modifications (screen-share or short video is fine)

That’s it—break the encryption, keep the functionality, and hand back a maintainable workbook I can build on.
