// Create profit margin column
= Table.AddColumn(#"Merged Queries", "Profit Margin", 
  each ([Revenue] - ([Quantity] * [Cost])) / [Revenue])

// Group sales by region
= Table.Group(#"Added Custom", {"Region"}, 
  {{"Total Revenue", each List.Sum([Revenue]), type number}})

Dynamic Array Formulas (Excel 365)

4.9 New Excel Functions Revolution

XLOOKUP: VLOOKUP's Superior Replacement

Syntax: =XLOOKUP(lookup_value, lookup_array, return_array, if_not_found, match_mode, search_mode)

Advantages over VLOOKUP:

Look left or right: No column limitations
Exact match default: No need for FALSE parameter
Custom error messages: Replace #N/A with meaningful text
Multiple criteria: Built-in support

XLOOKUP Examples

// Basic lookup
=XLOOKUP(E2, A:A, B:B, "Not Found")

// Multiple criteria lookup
=XLOOKUP(1, (A:A=E2)*(B:B=F2), C:C)

// Return multiple columns
=XLOOKUP(E2, A:A, B:D)

4.10 Dynamic Array Functions

FILTER: Extract Data Based on Criteria

// Filter sales > $1000
=FILTER(A2:D100, D2:D100>1000)

// Multiple criteria
=FILTER(A2:D100, (B2:B100="North")*(D2:D100>500))

// Return all columns for matching rows
=FILTER(A:D, A:A=E2)

SORT: Automatic Data Sorting

// Sort by column 3 descending
=SORT(A2:D100, 3, -1)

// Multiple sort criteria
=SORT(A2:D100, {2,3}, {1,-1})

UNIQUE: Remove Duplicates Instantly

// Unique values from column A
=UNIQUE(A2:A100)

// Unique combinations
=UNIQUE(A2:C100)

4.11 Advanced Formula Combinations

Dynamic Data Validation Lists

// Create dynamic dropdown based on category
=UNIQUE(FILTER(Products, Categories=B2))

Automated Top 10 Reports

// Top 10 salespersons with revenue
=SORT(FILTER(A2:C100, C2:C100<>""), 3, -1)

Real-Time Dashboard Updates

// Current month sales summary
=SUMIFS(Revenue, Dates, ">="&DATE(YEAR(TODAY()),MONTH(TODAY()),1))
