FAQ
Can you convert complex Excel formulas and VBA macros into Python/React?
Yes. I translate your Excel formulas, conditional formatting, and VBA macros directly into backend Python (FastAPI) or JavaScript logic, ensuring faster performance and zero formula corruption.
Will my team still be able to export data back to Excel or CSV?
Absolutely. Your custom web application will include one-click export features so you can download reporting data to Excel or PDF whenever needed.
Do you offer multi-user access with different permission levels?
Yes, the Standard and Premium packages support Role-Based Access Control (RBAC), allowing you to restrict access for employees, managers, and external vendors.
What is required before we start?
Simply send me a message with your sample Excel or Google Sheet or/and a brief explanation of what you want your web app to do. I will review it and guide you on the best structure.
