Introduction: Why Excel and Google Sheets Remain the Main Tools for Analysts
In July 2026, it's hard to imagine a business that doesn't rely on data. Sales reports, marketing dashboards, financial models, procurement planning—all of this is built on spreadsheets. According to Statista, in 2025, over 1.5 billion people worldwide used Excel, and about 800 million used Google Sheets. And these numbers continue to grow. Why? Because even in the era of BI platforms and complex analytical systems, Excel and Google Sheets remain the most accessible, flexible, and fastest tools for working with data. But there's a catch: to extract real value from them, you need to go beyond basic sums and VLOOKUPs. You need advanced analytics: pivot tables, conditional functions, VBA macros, report automation. And that's exactly what the course "Excel and Google Sheets" on the asibiont.com platform teaches.
I recently completed this course and want to share an honest experience. No advertising clichés—just facts, details, and practical results.
What Is This Course and Who Is It For?
The course "Excel and Google Sheets" on asibiont.com is a practical program that covers both tools: classic Excel and cloud-based Google Sheets. It is designed for business users—those who work with data every day but want to do it faster, more accurately, and without unnecessary routine.
| Parameter | Description |
|---|---|
| Target Audience | Managers, analysts, marketers, financiers, entrepreneurs |
| Level | From beginners (know what a cell and sum are) to advanced (want to master macros and scripts) |
| Format | Text lessons, practical tasks, tests |
| Feature | AI generation of personalized lessons for each student |
The course is not about theory for theory's sake. It's about specific skills: how to build a pivot table in 30 seconds, how to write a macro that automatically updates a report every Monday, how to visualize data so that your boss understands everything at a glance.
What I Learned: Specific Skills
Before the course, I could do basic things: SUM, VLOOKUP, simple charts. That was enough for small tasks, but when I was tasked with creating a dashboard on the effectiveness of advertising campaigns over six months, I realized my knowledge was insufficient. The course gave me tools that I immediately applied at work. Here's what I mastered:
1. Advanced Formulas
I learned to use INDEX+MATCH instead of VLOOKUP (faster and more flexible), SUMIFS with multiple conditions, ARRAYFORMULA in Google Sheets to process entire columns with one formula. For example, I used to spend 15 minutes calculating the average check per manager—now it takes 3 seconds.
2. Pivot Tables and Dashboards
Pivot tables are a must-have. I learned to build them in Excel and Google Sheets, configure slicers and timelines, create interactive dashboards that update automatically when new data is added. Now I have a sales dashboard where I see weekly dynamics, top 10 products, and conversion—all updated with one click.
3. Data Visualization
Charts are not just lines and columns. I learned how to choose the right chart type for each task (e.g., pie chart for proportions, line chart for trends, histogram for distribution). I mastered conditional formatting: highlighted cells with sales declines in red, growth in green. This saved hours of reading reports.
4. VBA Macros and Google Apps Script
This was my main goal. VBA (Visual Basic for Applications) is the macro language in Excel. I wrote a macro that every day at 9 AM loads data from CRM, cleans it, builds a report, and sends it by email. Google Apps Script (a JavaScript-like language for Google Sheets) allowed me to automate data import from Google Analytics. Now reports are prepared without my involvement.
5. Report Automation
The course taught me not just to calculate but to design processes. I learned how to set up automatic data updates from external sources (APIs, CSV files, databases), how to use Power Query in Excel for data collection and transformation. Result: I reduced the time for preparing a weekly report from 4 hours to 40 minutes.
How Learning Works on asibiont.com
The learning format surprised me. It's not the usual video lessons (there are none on the platform) or boring PDF instructions. Everything is built on AI generation of personalized lessons. How it works:
- You choose a topic (e.g., "pivot tables").
- The AI neural network analyzes your level: if you're a beginner, it starts with basics; if advanced, it immediately gives complex cases.
- A lesson is generated—text with explanations, examples, formulas, and links to documentation. Lessons are written in simple language, without jargon.
- After the lesson, a practical task (e.g., "build a pivot table using data from the attached file").
- A test to check knowledge.
Why is this cool? Because the program adapts to you. I skipped the basics (sums, simple formulas) and immediately moved to macros—the AI understood this and didn't force me to go through what I already knew. If I got stuck on a topic, the neural network would explain it differently, with other examples.
Access to lessons is 24/7—I studied in the evening after work, on weekends, even on the subway (the course is text-based, readable on a phone). No schedule constraints.
Why AI Learning Is the Future (and Present)
I've learned in different ways: attended in-person courses (expensive, need to adapt to the group), watched YouTube (chaotic, no system), read books (boring, little practice). AI learning on asibiont.com solved all these problems:
- Personalization. The neural network doesn't give the same material to everyone. It adapts the program to your level, pace, and goals. If you grasp quickly, you move forward; if the topic is difficult, it explains again.
- 24/7 Accessibility. No need to wait for a course start or webinar recording. Started at 2 AM? No problem.
- Practice. Each lesson ends with a task. You don't just read—you do. And this gives real skills.
- Modern Content. AI automatically updates lessons using the latest versions of Excel and Google Sheets. For example, when Microsoft added new functions to Excel 2025, lessons on asibiont.com updated within a week.
- Explaining Complex Things Simply. The neural network can break things down: "Imagine a pivot table is a constructor. You take a column with dates, a column with amounts, and say: show me the sum of sales for each day." Understandable even for those who have never worked with spreadsheets.
According to a McKinsey report for 2025, companies that implemented AI learning for employees reduced the time to master new skills by an average of 40%. And I felt this myself: in 3 weeks, I completed a program that would have taken 2-3 months in a regular format.
Who Will Benefit from This Course
The course "Excel and Google Sheets" is suitable for a wide range of professionals. Here are the main groups:
| Audience | Why They Need the Course |
|---|---|
| Sales Managers | Build deal reports, analyze funnels, automatically calculate bonuses |
| Marketers | Analyze campaign effectiveness, build dashboards for CPA and ROI, import data from ad accounts |
| Financiers | Create financial models, forecast cash flow, automate reconciliations |
| Data Analysts | Master advanced formulas and scripts for processing large datasets |
| Entrepreneurs | Keep records without hiring an accountant, control key business metrics |
| Students | Gain a skill that gives an advantage in internships or first jobs |
A concrete example from my life: a colleague from the procurement department spent 3 days preparing a monthly inventory report. I showed her how to make a pivot table and macro—now she does it in 2 hours. The course gives exactly such skills: applied, measurable, useful.
Results: What I Got After the Course
Two months have passed since completing the course. Here are specific results:
- Automated 80% of weekly reports. I used to sit with them every Friday until 10 PM. Now I leave at 6 PM.
- Learned to build dashboards used by the entire team. My manager said, "Finally, I see the whole picture."
- Mastered VBA and Google Apps Script—now I can write macros for any task. This increased my value as a specialist.
- Reduced time for finding errors in spreadsheets: conditional formatting and data validation functions help spot anomalies in seconds.
