Why master Excel formulas in 2026
Excel remains the most widely used office tool in French speaking Switzerland, from small SMEs to international headquarters. But simply opening a workbook is no longer enough: what really makes the difference is the ability to turn a spreadsheet into a decision making tool. Excel formulas and functions are precisely what enables this shift from a static spreadsheet to dynamic analysis.
Without formulas, Excel is just a grid. With the right functions, you automate calculations, cross reference data, make your reports reliable, and save serious time on repetitive tasks. This Excel formulas and functions training gives you these reflexes in half a day, starting from the basics and going all the way to nested functions.
The Excel functions used the most on a daily basis
In real working environments, a handful of functions covers most business needs. The training tackles the ones found in the vast majority of professional workbooks: SUM, AVERAGE, MAX, and MIN for basic calculations, IF, AND, and OR for conditional logic, COUNTIF and SUMIF for conditional counts and totals, and VLOOKUP to pull information from another table.
You also learn date functions (TODAY, MONTH, DAY, WEEKDAY) to calculate deadlines, text functions (LEFT, CONCAT, UPPER, SEARCH) to clean and reformat imported data, and rounding functions to present readable numbers. All of this is practiced on real cases, not in theory.
From the basics to modern Excel 365 functions
Microsoft has been evolving Excel with more powerful and simpler functions over the past few years: XLOOKUP (a clear upgrade over VLOOKUP), FILTER and UNIQUE (to extract and deduplicate data in a single formula), and LET (to make complex formulas more readable). These modern functions are mentioned and positioned during the Excel formulas and functions training, so you know what to learn next.
To go further on these Excel 365 functions and on advanced modeling, the Excel Formulas and Functions Advanced course is the natural next step after this half day, covering dynamic array formulas, structured references, and advanced auditing techniques.

FAQ Excel formulas and functions training
What is the difference between an Excel formula and an Excel function?
A formula is a calculation you write yourself in a cell (for example =A1+B1). A function is a built in shortcut provided by Excel (such as SUM, AVERAGE, VLOOKUP) that performs a more complex calculation for you. Most formulas combine operators with functions.
Should I learn VLOOKUP or XLOOKUP?
VLOOKUP is still the most common function in business and the training covers it. XLOOKUP is more recent and is now recommended by Microsoft for its simplicity and robustness. The training mentions XLOOKUP and the Excel Formulas Advanced course puts it into practice.

Yes, as long as you already know how to use Excel to enter data and apply basic formatting. If you are completely new to Excel, the Excel Level 1 course is a better first step.
