Why Spreadsheets Are Trending Again
In the era of big data and BI systems, Excel and Google Sheets remain the most accessible analysis tools. According to the Stack Overflow Developer Survey 2025, over 60% of respondents use Excel for data work — more often than Python or R. The reason is simple: everyone has spreadsheets, and the entry barrier is minimal. But to turn them into a powerful analytical tool, you need advanced skills: pivot tables, Power Query, and report automation.
The "Excel and Google Sheets" course on the asibiont.com platform is designed for those who want to systematically master these tools — from basic formulas to VBA macros and dashboard building. Learning is built on AI generation of personalized lessons: the neural network adapts the program to your level and goals. Below, we'll break down what skills you'll gain and how they'll help your career.
What the Course Teaches: Three Approaches to Data Analysis
The course is based on a practical comparison of three ways to work with data. Each method has its strengths, and you'll learn to choose the optimal one for a specific task.
1. Formulas and Functions
This is the foundation: VLOOKUP, INDEX/MATCH, SUMIFS, text and logical functions. They provide flexibility and precision, but with large data volumes they become cumbersome. In the course, you'll master advanced techniques: dynamic arrays, LET and XLOOKUP functions, which simplify searching and replace outdated analogs.
2. Pivot Tables
Pivot Tables are the fastest way to summarize and analyze data. According to Microsoft, over 80% of Excel users have used pivot tables at least once, but only 20% use their advanced capabilities: grouping, calculated fields, slicers, and timelines. In the course, you'll learn to build interactive reports that update with one click.
3. Power Query and Automation
Power Query is an ETL (Extract, Transform, Load) tool for loading and transforming data without formulas. It allows you to combine data from different sources (CSV, web pages, databases), clean it, and automatically update reports. Google Sheets offers similar capabilities through Google Apps Script and the QUERY, IMPORTRANGE functions. In the course, you'll master both tools and be able to automate routine operations.
Comparison of Approaches: What to Choose?
| Criterion | Formulas | Pivot Tables | Power Query / Apps Script |
|---|---|---|---|
| Setup speed | High | Medium | Low |
| Flexibility | High | Limited | Very high |
| Automation | Low | Medium | High |
| Entry barrier | Low | Medium | High |
| Working with big data | Poor | Good | Excellent |
As the table shows, for simple tasks formulas are enough, for analysis — pivot tables, and for regular reports it's better to use Power Query. The course teaches you to combine these approaches depending on the business case.
How Learning Works on asibiont.com
The asibiont.com platform uses AI generation of lessons: the neural network analyzes your starting level and goals, then creates a personalized program. All lessons are text-based — convenient for those who prefer to read and immediately apply knowledge. Access to materials is open 24/7, you can learn at a comfortable pace.
Unlike traditional courses, there is no fixed program here: if you're already familiar with VLOOKUP, the AI will suggest more complex topics (e.g., Power Query or macros). If you're a beginner, you'll start with the basics. The neural network explains complex concepts in simple language, provides examples, and gives practical assignments for reinforcement.
Who Will Benefit from the Course
The "Excel and Google Sheets" course is suitable for:
- Beginner analysts — for mastering basic and advanced functions.
- Managers and marketers — for automating reporting and performance analysis.
- Finance professionals and accountants — for working with large tables and pivot reports.
- Entrepreneurs — for building dashboards and monitoring key metrics.
- Anyone who wants to boost productivity — automating routine saves hours of work.
Why AI Learning Is Modern and Effective
Traditional courses often suffer from being one-size-fits-all: some topics are too simple, others too complex. The AI approach solves this problem: the neural network adapts the program to your level, explains unclear points, and offers tasks that match your goals. You don't waste time on what you already know and don't skip what's important.
Moreover, the text format allows you to quickly find the information you need, return to lessons, and learn anywhere. AI generation of lessons means that materials are constantly updated and adapted to new versions of Excel and Google Sheets.
Practical Cases: How Skills Are Applied at Work
Let's look at typical tasks you'll be able to solve after the course:
- Consolidating data from 10 branches — using Power Query, you'll combine files into one report and set up auto-update.
- Analyzing sales by region — a pivot table with grouping and slicers will show dynamics in seconds.
- Automatic report distribution — a VBA macro or Google Apps Script will generate and send an email on schedule.
- Finding errors in data — formulas and conditional formatting will help quickly find duplicates and gaps.
These skills directly impact career prospects: according to HeadHunter, in analyst and manager job postings, the requirement "confident Excel skills" appears in 70% of cases. And the ability to work with Power Query and macros sets a candidate apart from others.
