Excel Matching Functions 2026: Is VLOOKUP Still Worth Using?
Compare VLOOKUP, XLOOKUP, and INDEX-MATCH for data reconciliation in Excel. Learn when each function works best and discover AI alternatives for fuzzy matching.
Every accountant has their favorite Excel function. But are you using the right one?
This guide covers the major Excel matching functions, when to use each, and their limitations.
Overview of Matching Functions
The Main Players
| Function | Excel Version | Difficulty | Power |
|---|---|---|---|
| VLOOKUP | All | Easy | Basic |
| HLOOKUP | All | Easy | Basic |
| XLOOKUP | 365+ | Medium | Advanced |
| INDEX-MATCH | All | Hard | Expert |
| SUMIF/COUNTIF | All | Easy | Aggregation |
What They Do
All these functions answer: “Given value A in list 1, what’s the corresponding value in list 2?”
VLOOKUP: The Classic
Syntax
=VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
| Argument | Meaning |
|---|---|
| lookup_value | What to find |
| table_array | Where to look |
| col_index_num | Which column to return |
| range_lookup | FALSE = exact match |
Example: Find Price by Product Code
| A | B | C |
|---|---|---|
| Code | Product | Price |
| A001 | Widget | ¥1,000 |
| A002 | Gadget | ¥2,000 |
| A003 | Sprocket | ¥500 |
=VLOOKUP("A002", A:C, 3, FALSE)
→ ¥2,000
Limitations
| Limitation | Problem |
|---|---|
| Left-to-right only | Lookup column must be leftmost |
| Column number | Changes when columns added |
| Exact match only | ”ABC Corp” ≠ “ABC Corporation” |
| First match wins | Doesn’t find duplicates |
| Slow on large data | Recalculates every cell |
When to Use
✅ Simple lookups ✅ Lookup column is leftmost ✅ Data is clean and consistent ✅ Small to medium datasets
HLOOKUP: VLOOKUP’s Sibling
Syntax
=HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup])
Same as VLOOKUP, but searches horizontally across rows.
When to Use
✅ Data organized in rows, not columns ✅ Headers across the top
Rarely Needed
Most real-world data is organized vertically. HLOOKUP is rarely used.
XLOOKUP: The Modern Choice
Syntax
=XLOOKUP(lookup_value, lookup_array, return_array, [if_not_found], [match_mode], [search_mode])
| Argument | Meaning |
|---|---|
| lookup_value | What to find |
| lookup_array | Column to search in |
| return_array | Column to return from |
| if_not_found | Custom error message |
| match_mode | 0=exact, -1=exact or smaller, 1=exact or larger, 2=wildcard |
| search_mode | 1=first to last, -1=last to first |
Example
=XLOOKUP("A002", A:A, C:C, "Not Found")
→ ¥2,000
Advantages over VLOOKUP
| Feature | VLOOKUP | XLOOKUP |
|---|---|---|
| Column order | Must be left | Any order |
| Error handling | Needs IFERROR | Built-in |
| Search direction | First only | First or last |
| Default behavior | Approximate match | Exact match |
| Multiple returns | No | Yes (array) |
Limitations
| Limitation | Problem |
|---|---|
| Excel 365+ only | Not in older versions |
| Still exact match | Variations not handled |
| Can be slower | Complex formulas |
When to Use
✅ Excel 365 or later ✅ Need flexibility in column order ✅ Want clean error handling ✅ Need to search from end
INDEX-MATCH: The Power Combo
Syntax
=INDEX(return_range, MATCH(lookup_value, lookup_range, 0))
| Function | What It Does |
|---|---|
| MATCH | Finds the position of lookup_value |
| INDEX | Returns value at that position in return_range |
Example
=INDEX(C:C, MATCH("A002", A:A, 0))
→ ¥2,000
Why Two Functions?
MATCH finds the row number, INDEX retrieves the value. Together, they’re more flexible than any single function.
Advantages
| Feature | INDEX-MATCH |
|---|---|
| Column order | Any |
| Performance | Faster on large data |
| Flexibility | Multiple criteria possible |
| Stability | Column references don’t break |
Limitations
| Limitation | Problem |
|---|---|
| Complex syntax | Harder to write |
| Still exact match | No variation handling |
| Error-prone | Easy to get ranges wrong |
When to Use
✅ Large datasets (faster than VLOOKUP) ✅ Need lookup column to the right ✅ Formulas may be copied/moved ✅ Power users comfortable with complexity
SUMIF/COUNTIF: Aggregation
SUMIF Syntax
=SUMIF(range, criteria, sum_range)
Example: Sum All Orders for Customer
| A | B |
|---|---|
| Customer | Amount |
| ABC Corp | ¥10,000 |
| XYZ Ltd | ¥5,000 |
| ABC Corp | ¥15,000 |
=SUMIF(A:A, "ABC Corp", B:B)
→ ¥25,000
When to Use
✅ Need totals, not individual values ✅ Multiple matches exist ✅ Aggregation required
Multiple Criteria Matching
SUMIFS (Multiple Conditions)
=SUMIFS(sum_range, criteria_range1, criteria1, criteria_range2, criteria2)
Example
Sum orders for ABC Corp in January:
=SUMIFS(C:C, A:A, "ABC Corp", B:B, ">=2026-01-01", B:B, "<=2026-01-31")
INDEX-MATCH with Array Formula
For multiple criteria lookup (Excel 365):
=INDEX(D:D, MATCH(1, (A:A=E2)*(B:B=F2), 0))
Common Matching Scenarios
Scenario 1: Find Matching Records
Find invoices in List A that exist in List B:
=IF(ISNA(MATCH(A2, ListB!A:A, 0)), "Not in B", "Match")
Scenario 2: Find Differences
Find records in A but not in B:
=IF(ISNA(VLOOKUP(A2, ListB!A:A, 1, FALSE)), "Only in A", "In Both")
Scenario 3: Compare Values
Find records where amount differs:
=IF(B2<>VLOOKUP(A2, ListB!A:C, 3, FALSE), "Different", "Same")
The Exact Match Problem
Why Excel Functions Fail
All Excel matching functions require exact character matches:
| Value A | Value B | Excel Result |
|---|---|---|
| ABC Corp. | ABC Corporation | No Match |
| 100-0001 | 1000001 | No Match |
| John Smith | JOHN SMITH | No Match |
Workarounds
| Issue | Workaround |
|---|---|
| Case differences | UPPER/LOWER functions |
| Spaces | TRIM function |
| Symbols | SUBSTITUTE function |
| Partial match | Wildcards (*) in XLOOKUP |
The Limit
Complex variations (misspellings, abbreviations, reordering) can’t be solved with formulas.
When to Move Beyond Excel
Excel Works When
- Data is perfectly clean
- Exact matches exist
- Small to medium volume
- One-time analysis
Excel Struggles When
- Notation varies (“Corp” vs “Corporation”)
- Data has typos
- Large volume (10,000+ rows)
- Recurring reconciliation task
- Speed matters
AI Alternative
AI performs fuzzy matching based on meaning:
| Scenario | Excel | AI |
|---|---|---|
| ”ABC Corp” vs “ABC Corporation” | ❌ | ✅ |
| Misspellings | ❌ | ✅ |
| Reordered names | ❌ | ✅ |
Function Selection Guide
Quick Reference
| Situation | Recommended Function |

| Need aggregation | SUMIF/SUMIFS |
| Multiple criteria | SUMIFS or INDEX-MATCH array |
Decision Flow
Is your Excel 365+?
├── Yes → Use XLOOKUP
└── No → Is lookup column leftmost?
├── Yes → Use VLOOKUP
└── No → Use INDEX-MATCH
