Your Excel files deserve better

Your Excel file has grown with your company. It has become essential, but also unmanageable: multiple versions, file conflicts, broken formulas, poor performance. And yet, it contains all your business logic.

We transform your critical Excel files into modern web applications. Your teams get a familiar interface, but with the power of a real application: real-time collaboration, access rights, modification history, automations.

The migration is smooth: we preserve your data, formulas and business rules. You continue working during the transition, and your teams are trained to use the new tool.

Our approach.

A risk-free migration, with no data loss.

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.

Benefits.

The advantages of a web application vs Excel.

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.

What our clients gain by migrating their Excel:

Real-time collaboration without version conflicts or corrupted files

Complete modification history with restoration capability

Accessibility from any device, without Excel installed

Advanced automations: alerts, calculations, reports, notifications
