Question 1

What is INDEX MATCH?

Accepted Answer

INDEX MATCH is a combination of two Excel functions that together perform powerful lookups. MATCH finds the position of a value, and INDEX returns the value at that position. It's considered the professional alternative to VLOOKUP.

Question 2

Why use INDEX MATCH instead of VLOOKUP?

Accepted Answer

INDEX MATCH has several advantages: 1) Can lookup left or right (VLOOKUP only looks right), 2) Doesn't break when columns are inserted, 3) Better performance on large datasets, 4) More flexible for complex lookups.

Question 3

How does the INDEX MATCH formula work?

Accepted Answer

In =INDEX(C:C, MATCH(A2, B:B, 0)): 1) MATCH(A2, B:B, 0) finds the row number where A2's value appears in column B, 2) INDEX(C:C, ...) returns the value from column C at that row number. The 0 means exact match.

Question 4

Is this tool free?

Accepted Answer

Yes, the INDEX MATCH Generator is completely free. No registration or credit card required. Generate as many formulas as you need.

Question 5

What is a two-way lookup (INDEX MATCH MATCH)?

Accepted Answer

A two-way lookup finds a value at the intersection of a row and column. The formula uses two MATCH functions: one to find the row position and one to find the column position.

Question 6

How do I use INDEX MATCH with multiple criteria?

Accepted Answer

For multiple criteria, multiply conditions together: =INDEX(return_range, MATCH(1, (criteria1_range=value1)*(criteria2_range=value2), 0)). Each condition returns TRUE(1) or FALSE(0).

Question 7

Should I use XLOOKUP instead?

Accepted Answer

If you have Excel 365 or Excel 2021, XLOOKUP is simpler for basic lookups. However, INDEX MATCH is still valuable for compatibility with older Excel versions and complex multi-criteria lookups.

Question 8

How do I handle #N/A errors?

Accepted Answer

Wrap your formula with IFERROR: =IFERROR(INDEX(C:C, MATCH(A2, B:B, 0)), "Not found"). Our generator has a checkbox to add this automatically.

Question 9

What do the match_type values mean?

Accepted Answer

0 = Exact match (most common). 1 = Less than or equal (data must be sorted ascending). -1 = Greater than or equal (data must be sorted descending). For most lookups, use 0.

Question 10

Can I lookup from right to left?

Accepted Answer

Yes! This is a key advantage of INDEX MATCH. Unlike VLOOKUP which only looks right, you can have your lookup column anywhere.

Question 11

Why is my formula not working?

Accepted Answer

Common issues: 1) Lookup and return ranges have different sizes, 2) Extra spaces in data (use TRIM), 3) Number stored as text (use VALUE), 4) Wrong match_type for your data.
