Accounts Done by Magic: How We Cut Reporting from Days to Minutes with Excel, Power Query, Power BI, AI Analytics and Smart Alerts
Every wizarding school needs accountants. Unfortunately, ours spent days each month wrangling spreadsheets, investigating unexplained variances caused by vampire attacks, and manually checking coding errors. So, we built a little magic of our own.
Jenny Blewett, Head of Global Finance at Costello Medical, shows how her finance team cut reporting from days to minutes using Excel, Power Query, Power BI, AI analytics and smart alerts, and how you can bring the same magic to your own month-end.
Other Sessions
Zainab and Vaughan show how to question a financial model, using AI to build scenarios, sensitivities and Data Tables, and why people trust some models and not others.
Sloka shows how a three-statement model feeds a valuation, what models can and can't tell you about value, and where valuations most often go wrong, using no-name examples.
Carolina shows how AI reads spreadsheets, Power BI models and other files as text, so it can create and edit real files reliably. A concrete, tool-agnostic answer to hallucination worries.
Danielle shows how nested arrays solve real modelling problems, and how review habits must change when one cell can hold a whole depreciation profile or scenario path.
