Power Excel

To whom:

Managers, finance, sales, marketing, quality leaders and experts, who daily use MS Excel for data processing, tracking, reporting, and analysis. 


Inspirational stories about computing's endless capabilities, machine learning and artificial intelligence are often distributed on social media. However, the real life of data processing tends to be much more grounded.

Daily reporting takes an increasing part of the day. Data from different sources must be collected manually. Files received from colleagues require extensive reformat efforts. People in the IT department are friendly, but practical help from them sometimes has to wait for weeks and months.

Good news – these situations can be avoided! But, on the way to a solution, must answer more nuanced questions. What to do with oversize Excel files? How to fix nonfictional links between different file forever? What to do if the data exceeds Excel limits? How to simply automate routine reporting?

ALet us find answers to these and other questions at Elchin Jafarov workshop Power Excel.”.
