Spreadsheet to Web Dashboard Conversion

You have an Excel workbook that runs your business. It's critical, complex, and held together with VLOOKUP and prayers. Here's how to turn it into a real application — without losing anything.

Why Convert?

• Version chaos — "Final_v3_UPDATED_Karl_edits_USE_THIS_ONE.xlsx"
• Formula breakage — one wrong edit cascades errors across 15 tabs
• Single point of failure — the builder is the only one who understands it
• No real-time data — always looking at yesterday's numbers
• No access control — everyone sees everything, or nobody sees anything

What You Get After Conversion

A Progressive Web App (PWA) dashboard replaces the spreadsheet entirely: live data connected to sources, any-device access, interactive charts and filters, role-based access, alerting, and a full audit trail.

The Conversion Process

Phase 1: Discovery (Days 1-3)

We open your spreadsheet and map everything: every formula, data source, tab, and macro. We identify business logic (keep), presentation (redesign), and workarounds (eliminate).

Phase 2: Data Architecture (Days 3-5)

Data moves from cells into a proper database — queryable, auditable, feeding multiple views. Automated connections to upstream sources are established.

Phase 3: Dashboard Build (Days 5-12)

Using your spreadsheet as the spec, we build the dashboard. Every chart, KPI, and table — now interactive, real-time, and accessible from anywhere.

Phase 4: Testing & Deployment (Days 12-15)

We run the dashboard alongside your spreadsheet to verify numbers match. Once validated, we deploy and train your team.
