¿Quieres dominar Excel a nivel avanzado? He preparado un PDF exclusivo con ejercicios prácticos y resueltos para que practiques funciones, modelado y automatización. Ideal para analistas, contadores y cualquier persona que quiera subir de nivel.

Ejercicio 1: BUSCARX con múltiples criterios y búsqueda inversa

Ejercicio 2: FILTRO avanzado con múltiples condiciones dinámicas

The PDF is structured as a "challenge-based" workbook, providing a problem statement followed by the solution methodology. The content generally covers four pillars of advanced Excel usage:

1. Advanced Formula Logic & Nested Functions The exercises shine when dealing with nested logic. The material moves beyond simple VLOOKUP usage, introducing users to the more powerful INDEX and MATCH combination, and the modern XLOOKUP function. It provides excellent practice with conditional logic using IF, AND, OR, and the critically important IFERROR function to make spreadsheets bulletproof against missing data.

2. Array Formulas and Dynamic Arrays One of the standout sections focuses on Array formulas (CSE formulas) and Excel’s newer Dynamic Array functions like UNIQUE, FILTER, and SORT. These exercises are often missing from older textbooks, making this PDF feel modern and relevant. The practice files allow users to manipulate data arrays in real-time, which is essential for modern data cleaning.

3. Pivot Tables and Power Pivot The exercises dedicated to Pivot Tables go deeper than simple summarization. They introduce calculated fields, grouping, and slicers. More impressively, it touches upon Power Pivot and the Data Model, teaching users how to create relationships between tables without needing VLOOKUP—a key skill for anyone handling relational databases within Excel.

4. Automation with Macros and VBA The final section introduces automation. Rather than overwhelming the user with full coding theory, it provides practical Macro exercises. Users learn to record macros for formatting and report generation, and the PDF includes an introduction to the VBA editor to make minor code adjustments—a vital skill for customizing workflow automation.
