We analyze your files in detail: data structure, critical formulas, VBA macros, links between sheets. We identify what needs to be preserved and what can be improved.
We design an optimized data structure that faithfully reproduces your business logic. Relationships between data are explicit, calculations are reliable, performance is guaranteed.
Your users won't be lost: we create interfaces that follow Excel conventions (tables, filters, exports) while adding the features of a real web application.
An Excel file shared between multiple users is guaranteed chaos: conflicting versions, overwritten data, lost history. A web application solves all these problems.
Your data is centralized, secured and accessible everywhere. Each user has the rights that correspond to their role. Every modification is tracked and can be undone.
And you keep what makes Excel powerful: tables, filters, exports. Your teams find their bearings instantly.
