The Excel array formulas training introduces you to the dynamic array functions that have transformed Excel over the past few years. In one intensive half day, you discover FILTER, UNIQUE, SORT and the modern array functions that let you extract, deduplicate and sort data in a single formula. A major Excel 365 advance for anyone working with data in French speaking Switzerland.
Discover the new generation of Excel functions that change the game
Across the Swiss French speaking region, knowing FILTER, UNIQUE and dynamic array functions clearly puts your Excel mastery at the top of the pack. This Excel array formulas training favors hands on practice: dynamically extracting subsets, deduplicating a list, sorting without touching source data, validating entries via a dynamic range. You walk away with reflexes immediately applicable and course materials to go further.
Module 1: Dynamic array Functions
Module 2: Dynamic data validation
Microsoft has deeply renewed Excel’s calculation engine with dynamic array functions. FILTER, UNIQUE, SORT, SEQUENCE now make possible in a single formula what previously required complex formulas or VBA. Mastering these modern array formulas places your Excel level at the top of the pack.
The interest is very concrete: these functions replace dozens of manual operations. Filtering a list without touching the data, pulling unique values from a range, sorting dynamically: everything becomes a single formula that updates automatically when the source data changes.
The training gives a central place to the two most used functions: FILTER and UNIQUE. FILTER lets you extract rows from a range that meet a criterion, without using Excel’s classic filters. UNIQUE returns the distinct values from a range, ideal for generating selection lists or cleaning duplicates.
These two array formulas combine powerfully: FILTER on the output of UNIQUE, UNIQUE on the result of a search, etc. The use cases covered in training come from the daily work of analysts and management controllers.
Beyond FILTER and UNIQUE, the course covers SORT to order a range without touching source data and SEQUENCE to generate numerical sequences. These functions are less known but open new possibilities, notably for building dynamic dashboards or parameterizable lists.
Dynamic data validation is another concrete application: a drop down list that updates automatically when new entries are added to the source. This technique relies on the dynamic ranges generated by modern array formulas.
The training also explains the difference between classic array formulas (validated with Ctrl+Shift+Enter) and Excel 365 dynamic array formulas. The former are still useful in some cases, the latter are the new standard. Understanding this evolution helps read and adapt existing Excel workbooks that mix both approaches.
The Excel array formulas training is designed for management controllers, analysts, reporting managers, self employed professionals and any advanced Excel users who want to master modern Excel 365 functions. Regular Excel use and good mastery of classic functions (VLOOKUP, IF, SUMIF) are required.
At our ITTA centers in Carouge and Le Flon, this Excel array formulas training runs as an intensive half day with an expert instructor and a small group to ensure personalized follow up. You work on concrete cases, test each array function on your own data and leave with course materials.
What is an array formula in Excel?
It is a formula that returns multiple values at once and automatically expands across a range of cells. Functions like FILTER, UNIQUE and SORT are typical examples.
Do I need Excel 365 to use FILTER and UNIQUE?
These dynamic array functions are available in Excel 365, Excel 2021 and more recent versions. They are not present in Excel 2019 or earlier.
What is the difference between FILTER and Excel’s classic filter?
The classic filter hides rows in the source range. FILTER creates a new dynamic range with only the rows matching the criterion, without touching the source data.
Do array formulas replace pivot tables?
No, they are complementary tools. Array formulas excel at precise dynamic extractions, pivot tables remain unbeatable for multi axis summaries.
Do I need advanced formulas before this training?
Yes, good mastery of classic functions (VLOOKUP, IF, SUMIF) is required. The Advanced Excel Training is an ideal prerequisite.
Is this training held in Geneva?
Yes, the training takes place at the ITTA center in Carouge in Geneva, at Le Flon in Lausanne and in a virtual classroom.
What are the typical use cases of array formulas?
Dynamic extraction of subsets, list deduplication, auto updated drop down lists, parameterized sorts, dynamic ranges for charts.
Advanced Excel users wanting to master dynamic array functions (FILTER, UNIQUE, SORT, SEQUENCE) introduced with Excel 365. In Geneva and Lausanne, the course welcomes participants from international organizations, banking, consulting and growing SMEs. No specific prerequisite is required other than a concrete willingness to progress on the subject.
You leave with an operational mastery of the fundamentals, reusable canvases on your concrete cases, a structured action plan for the weeks that follow. Many participants report a visible effect from the first week back, with sustainable anchoring over four to six weeks of regular practice. The course combines short theory inputs, practical exercises on your real situations and personalized trainer debrief.
An analyst replacing complex formulas with simple readable arrays. A controller producing dynamic extracts without pivot tables. A consultant creating Excel tools based on modern functions. The course adapts exercises to your context with personalized trainer feedback, and each participant leaves with an action plan calibrated to their own situation.
Combines well with Excel Advanced formulas for XLOOKUP/LET base, Excel Dashboards for application, Power Query for upstream preparation. Many participants enroll in one of these courses in the following trimester, according to their current priority and professional context.
Dynamic array functions (FILTER, UNIQUE, SORT, SEQUENCE, RANDARRAY) introduced with Excel 365 radically transform calculation methods. They unlock previously impossible use cases and simplify manipulations that required very complex formulas.
Most participants report a noticeable effect from the first week of return, with deeper anchoring over four to six weeks of regular practice on real files. The course closes with a personalized practice plan calibrated on your professional context.
The features covered are used daily by millions of professionals across Geneva and Lausanne organizations. Mastery transforms repetitive work into efficient routine. This training relies on real cases and offers an outfitted approach calibrated for the 2025-2026 evolutions of the platform.
At ITTA centers in Geneva and Lausanne, this course runs in a small group with an expert trainer and a format alternating concise theory, practical exercises and personalized debrief. Group confidentiality is explicit and held. Each participant arrives with a real case and leaves with an action plan calibrated to their context. The course integrates recent evolutions of the domain (digital tools, hybrid formats, 2025-2026 practices) without losing focus on fundamentals.
Need Excel 365?
Yes, these functions are not in Excel 2019 perpetual.
Is LAMBDA addressed?
Yes, LAMBDA is introduced as extension.
Difference with pivot tables?
Array functions offer a dynamic alternative to pivot tables for some cases.
Where do sessions take place?
ITTA has three centers in French speaking Switzerland: in Geneva (Carouge, Route des Jeunes 35), in Lausanne at the Flon (Rue des Cotes de Montbenon 16) and at Lausanne Mon-Repos (Avenue de Mon-repos 24). The training is also available in virtual classroom.
