📊 Method 1: Using VLOOKUP

VLOOKUP can find matches between lists, but has limitations: =VLOOKUP(A2, Sheet2!A:A, 1, FALSE) If the formula returns #N/A, the item doesn't exist in the second list. **Pros:** Built into Excel **Cons:** Slow with large lists, shows errors instead of clean results

🔍 Method 2: Using MATCH

MATCH is more flexible than VLOOKUP: =IF(ISERROR(MATCH(A2, Sheet2!$A$1:$A$100, 0)), "Unique", "Match") This formula labels each row as "Unique" or "Match". **Pros:** Clear labeling **Cons:** Still requires manual formula setup per list

🎨 Method 3: Conditional Formatting

For visual comparison: 1. Select your first list 2. Go to Home → Conditional Formatting → New Rule 3. Use formula: =COUNTIF(Sheet2!$A:$A, A1)=0 4. Choose a highlight color Items not in the second list will be highlighted. **Pros:** Visual and intuitive **Cons:** Doesn't give you a clean output list
