From Excel to Power BI: A Journey of Business Transformation | Xyclos
Updated: Sep 19
The Beginning: An Excel Course that Opened Doors
It all started when Diego took an intermediate-advanced business Excel course. That's where he met me, and after about a year he called me because he was interested in implementing Power BI in his company. Initially, we planned five sessions for this exciting project.
First Session: Evaluation of the Current Scenario
In the first session, Diego sent me an Excel file consisting of five tabs. The first contained a summary of the data for August 2024.
Looking through it, I noticed the use of advanced formulas and the SUMIFS function, which told me that Diego’s team already had a good understanding of Excel. This solid starting point was crucial to our journey into Power BI.
The remaining four sheets contained the company's production processes: from the receipt of raw materials, through the registration of outputs and production, to the registration of product dispatches. All sheets were defined as tables, which demonstrated an excellent use of Excel.
The Importance of a Good Data Structure
This clever use of Tables in Excel would greatly facilitate our transition to Power BI.
It's an excellent example of how a good data structure in Excel can lay the foundation for more advanced analysis with tools like Power BI.
Setting the Stage for Power BI
When I asked about the history of these files, Diego informed me that they had them since January 2024. This was the perfect time to introduce one of the fundamental concepts in Excel: managing lists or databases.
I explained to them the importance of this concept and guided them in consolidating the four process sheets for each month (January to August) into a new workbook.
This consolidation would not only improve your data handling in Excel, but also prepare us for future implementation in Power BI.
Second Session: Optimizing Formulas and Efficiency
In the second session, we reviewed the consolidated files that were sent to me. As I examined the sheets one by one, I noticed that in some of them a formula was manually repeated for each record.
I took this opportunity to teach them a more efficient method: using absolute cell references. This technique would not only save time, but would also reduce errors and improve data consistency.
Pro Tip:
Using absolute references ($F$1) is a crucial Excel skill that can save hours of work and minimize errors. It's one of the many topics we cover in our Intermediate-Advanced Excel course.
We started the session by implementing all the necessary changes. In addition, I taught them how to create custom formats, an essential skill to correctly identify cells containing numerical values. This knowledge not only improves the presentation of the data, but also facilitates its subsequent analysis in Power BI.
Data Validation: A Crucial Step
Diego, the manager, expressed his concern about the validity of the data, a concern that was entirely justified. I took this opportunity to introduce a powerful Excel tool: pivot tables.
I showed them how to use them to validate the new consolidated file against the original monthly files, thus ensuring the integrity of the process.
Pro Tip:
Pivot tables are an essential tool in Excel for data analysis and validation. Mastering them not only improves your efficiency in Excel, but also eases the transition to more advanced BI tools.
Third Session: Identifying Opportunities for Improvement
In the third session, I met with the person in charge of managing the archive.
I asked him to explain to me the process of entering data into each sheet.
During his explanation, I identified a pattern: a high percentage of repetitive and necessary information was entered manually. This observation opened the door to a significant optimization of the process.
Fourth Session: Automation and Efficiency
The analysis from the previous session led us to an innovative solution. For the fourth session, we prepared a table of codes and repetitive data, implementing the XLOOKUP function to use in the other sheets. This method allowed for much faster and more efficient data entry.
With each optimization, the satisfaction of the person in charge of Excel was evident.
" This is going to save me a lot of time ," he said enthusiastically. His happiness was palpable, and with good reason: we were turning hours of manual work into minutes of automated processes .
Testing and Preparing for Power BI
Naturally, we conducted extensive data entry tests with the new optimized method. The results were impeccable: everything worked perfectly.
With this success, we announced that in the next session we would take a crucial step: loading our consolidated databases into Power BI.
This moment marked the transition from optimization in Excel to the analytical power of Power BI, a leap that excited the entire team.
Fifth Session: Bringing Data to Life with Power BI
In the fifth session, we dive into Power BI .
We start by loading our optimized tables and creating the crucial date table , a fundamental component in any Power BI data model .
We then established the relationships in the data model , laying the foundation for powerful and flexible analysis.
With this foundation, we created our first report page focused on raw material receipt. We used a variety of visualizations:
Column and stacked column charts for comparing quantities
Pie charts to show proportions
Line charts to visualize time trends
These visualizations allowed us to clearly observe the behavior of material receipt over time, providing instant insights that would have previously required hours of manual analysis.
The Power of Interactivity
Once the report was created, I showed them how all the charts were integrated and, most importantly, how they could perform interactive queries.
Watching the data come to life before their eyes, answering their questions in real time, elicited expressions of wonder and happiness from the entire team.
Testimony:
"Seeing our data transform into actionable insights in just a few clicks is simply amazing. Power BI has revolutionized the way we understand our business." - Diego, Manager
Empowering the Team with Power BI Knowledge
During this session, we not only created visualizations, but I also taught you how to create your own visuals and charts in Power BI.
We explore the components of each visual element in detail, allowing you to become deeply familiar with the tool.
This practical approach not only gave them the “fish,” but also the “fishing rod,” empowering them to create their own reports and analysis in the future.
Designing the Data Narrative
Beyond the technical, we started planning the narrative we wanted to tell with Power BI. We discussed crucial questions:
What story do we want to tell with our data?
What specific analysis do we need in each report?
What data is essential to support our narrative?
What types of charts and graphs will help us communicate our insights more effectively?
This planning exercise was critical to ensuring our Power BI reports were not only technically sound, but also strategically valuable for business decision making.
Period of Assimilation and Reflection
Recognizing the amount of new information and the possibilities that had opened up, the team requested a few days to assimilate everything they had learned. This seemed to me not only appropriate, but essential.
Power BI represents a new analytics environment, and it’s important to allow time to adapt and reflect on how to integrate these new capabilities into existing processes.
Pro Tip:
The transition to Power BI is a journey, not a destination. Take the time to absorb each new concept and experiment with the tools. Constant practice is key to mastering Power BI.
Knowledge Transfer and Autonomy
To conclude this crucial session, we took an important step: we changed the source of the data. Initially, the data was pointing to a folder on my computer.
Now, we redirect them to a folder on Diego and his team's computer.
This seemingly simple change was actually a huge step towards team autonomy.
It would allow them to run tests on their own, experiment with the data in real time, and most importantly, start integrating Power BI into their daily processes without relying on my constant presence.
Pro Tip:
The true power of Power BI is revealed when teams are able to work with their own data autonomously. Fostering this independence from the start is key to the long-term success of any BI implementation.
The Road Ahead: Going Deeper into the Analysis
At this point, we have made significant progress on our journey from Excel to Power BI.
However, this is just the beginning. Our next step is to enrich each report page with advanced measurements and calculations. This will include:
Creating custom KPIs
Calculation of relevant percentages and averages
Development of business-specific indexes
Implementation of trend analysis and forecasts
These advanced measures will transform our reports from simple data visualizations into powerful decision-making tools, providing deep, actionable insights for every aspect of the business.
