What business owners usually want to know.
01Can you turn an Excel or VBA system into a web app?
Yes. The process starts by mapping formulas, macros, dependencies, exceptions, users, and outputs, then moves bounded workflows into modern software with verification at each stage.
02Will we lose the business logic that already works?
The aim is to preserve valuable domain logic, test it against known outputs, and replace fragility around it. A rewrite should not casually discard rules the business depends on.
03Can the old spreadsheet and new platform run together during migration?
Yes. Compatibility bridges and controlled comparisons can support a phased transition until the web workflow proves it can safely become authoritative.
