Hello, I’m Bartosz Czapiewski, the author of the SkuteczneRaporty.pl and ExcelBI.pl blogs. I invite you to my Academy, where I share my knowledge from many years of work on reporting projects.

Thanks to the courses at the Academy, I have helped thousands of people change their reports and careers . You will find there as much as 13 hours of free video with the possibility of asking questions and obtaining a certificate:

  • Excel formulas and data operations (5 h)
  • Excel Pivot Tables (6h)
  • Reporting on maps in Excel & Power BI (2 h)

How can any Excel user automate their work with data and create attractive, interactive dashboards?

In my opinion, each analyst should then follow the new Excel learning curve, learning in turn: Power Query, Power Pivot (including data modeling and DAX), dashboards in Excel and Power BI. The next stages are available at the Academy for a fee, but it is worth investing in them, as shown by the stories of participants whom the courses allowed:

  • make better business decisions,
  • gain recognition and self-confidence,
  • get promoted or get a better paid job,
  • plan and better implement their professional career.

Begin a new stage in your life

Learning the POWER add-ins in Excel will allow you to make significant changes in the reporting processes:

  • you will save working hours by automating reporting (Power Query),
  • you will improve the quality of data by catching errors (Power Query),
  • you will build transparent data models with KPIs (Power Pivot / Power BI),
  • you will develop intuitive and interactive dashboards (Excel / Power BI).

9 out of 10 Excel users have not heard of them at all, so after the courses you have a great chance to become the king of reporting and an agent of changes in your organization.

Each of us has the power to change the stories of people in need. By purchasing the course, you support the Puppet program run by the Polish Humanitarian Action with me. Puppet helps malnourished children by financing meals in schools and community institutions.

From each course sold at the SkuteczneRaporty.pl Academy, 5% of the gross value is transferred to PAH:

1 course = 10 meals

1 package = 14 meals

I support the action which, in my opinion, provides “wise” help – the support goes to those children in Poland and around the world who need meal sponsoring, and who, for various reasons, are not supported by social welfare centres.

Get ready to work with POWER add-ins by getting to know (or repeating) Excel with me in free online courses:

  • Excel formulas and data operation (5 h)
  • Excel Pivot Tables (6 h)
  • Reporting on maps in Excel & Power BI (2 h)
