• Automate data preparation and reporting workflows

• Design robust, maintainable Excel solutions

• Reduce errors and manual work in expert-level spreadsheets

• Apply modern Excel features in real business scenarios

• Act as Excel “go to experts” within their organization

Module 1: The New Excel Engine

From legacy Excel to Modern Excel

• How dynamic arrays changed Excel fundamentally
• Spill behavior and calculation logic
• Volatile vs non volatile formulas
• Best practices for performance in large models

Hands-on:

• Converting legacy formulas to dynamic equivalents

Module 2: Core Dynamic Array

Functions Essential Functions

• FILTER() – advanced multi-condition filtering
• SORT() & SORTBY() – dynamic ordering
• UNIQUE() – deduplication logic
• SEQUENCE() – dynamic time series & IDs Advanced Combinations
• Nested dynamic arrays
• Dynamic dashboards without PivotTables
• Error safe dynamic formulas

Hands-on:

• Build a dynamic reporting table with zero helper columns

Module 3: Next- Generation Lookup & Text Functions Modern Lookup Logic

• XLOOKUP() vs VLOOKUP() / INDEX-MATCH
• XMATCH() for advanced matching
• Multi-return lookups with spill ranges
• New Text & Array-Shaping

Functions

• TEXTSPLIT()
• TEXTBEFORE() / TEXTAFTER()
• VSTACK() / HSTACK()
• TAKE() / DROP()
• TOROW() / TOCOL()

Hands-on:

• Clean, reshape, and merge multiple datasets dynamically

Module 4: Dynamic Charts & Visual Models

• Dynamic named ranges (modern approach)
• Charts driven by spill ranges
• Interactive models using data validation + arrays
• Replacing PivotCharts with dynamic formulas

Hands-on:

• Build a fully dynamic chart that updates automatically

Module 5: LET – Readable & Maintainable Formulas

• Why LET is essential for experts
• Breaking complex formulas into logical steps
• Performance and readability benefits

Hands-on:

• Refactor a “monster formula” using LET

Module 6: LAMBDA – Create Your Own Excel Functions

Core Concepts

• What LAMBDA is and why it matters
• Naming and storing custom functions
• Parameters, logic, and reuse Advanced Use
• Recursive LAMBDA functions
• Error handling inside
• LAMBDA

Hands-on:

• Create reusable business logic functions (e.g. KPI scoring, pricing rules)

Module 7: Functional Excel – MAP, REDUCE & SCAN

• New Functional Functions
• MAP() – apply logic across arrays
• BYROW() / BYCOL()
• REDUCE() – cumulative logic
• SCAN() – running totals and advanced sequences
• Use Cases
• Advanced calculations without helper columns
• Complex aggregations and transformations

Hands-on:

• Build a functional Excel solution replacing multiple formulas

Module 8: Automation & the Excel Ecosystem

• Power Query (Expert Perspective)
• When Power Query is the right tool
• Combining PQ with dynamic arrays Office Scripts & Copilot (Overview)
• Introduction to Office Scripts (Excel for the web)
• Automating repetitive expert tasks
• How Copilot enhances expert Excel workflows (analysis, formula generation, insights)

Hands-on:

• Design an end to end automated reporting workflow
