In Excel: use =INDEX(return_range, MATCH(lookup_value, lookup_range, 0)) — MATCH finds the row number of the lookup value and INDEX returns the value in that row from any column, left or right.

Syntax
Arguments
| Argument | required / optional | Description |
|---|---|---|
return_range | required | The column you want a value returned from. |
lookup_value | required | The value MATCH searches for. |
lookup_range | required | The column MATCH searches through for the lookup value. |
match_type | optional | 0 for an exact match (embedded as the third argument of MATCH); 1 or -1 for approximate. |

Decide the return_range — the column you want the answer from — and start with =INDEX(that range,.
Inside INDEX, open MATCH( and click the cell holding the value to find.
Select the column to search through as the second MATCH argument.
Type 0 as the third MATCH argument to force an exact match, then close both brackets.
Press Enter and fill the formula down; lock ranges with $ if you will copy it.
What this does
INDEX/MATCH pairs two functions to do a lookup that VLOOKUP cannot: MATCH returns the position of the lookup value within a column, and INDEX returns the cell at that position in whatever column you choose. Because the search column and the return column are independent, it can look to the left and it survives inserted or moved columns that would break a VLOOKUP col_index_num. Most people learn this as a sequence of clicks and forget it by next week; learning it as a pattern instead is what lets you apply it to the next, slightly different version of the problem without starting from scratch. That is the difference this page is trying to make. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “use index match in excel”. Start on a copy or a tiny sample, keep the affected cells visible, and compare the result with the outcome you expected before you touch the real workbook. When a formula is involved, keep the inputs labelled beside it, reference cells instead of typing values, and apply number formatting only after the result checks out. The point is a data step that keeps your analysis trustworthy, but the practical win is that someone else can open the file and understand what happened without asking you.
A worked example
Names are in column C (C2:C100) and IDs in column A (A2:A100). To return the ID for the name in E2 — a value to the LEFT, which VLOOKUP cannot do: =INDEX(A2:A100, MATCH(E2, C2:C100, 0)). MATCH finds "Maria" in row 7 of the range and INDEX returns the ID in A8, for example 1042. INDEX/MATCH is the durable lookup professionals reach for when data is wide or volatile: it looks in any direction and does not break when columns shift. Check the referenced cells, argument order and result type in your workbook. Start with the worked example before changing an input, then compare the changed result with the calculation you expected. An error value or a result of a different type is a reason to inspect the inputs and arguments.
In Google Sheets
The standard worksheet functions used by this example are listed in Google Sheets. Check the cell references, argument separators and input types in the target spreadsheet, then compare the worked result. This formula-availability check does not establish identical menus, keyboard shortcuts or workbook features, and it is not a product execution test. The aim was to get you unstuck fast and leave you a little more capable than a copy-paste would. The answer is at the top and the detail above shows why it holds — so the next time a colleague asks, you can answer without reaching for search. For “use index match in excel”, keep the input cells and the result visible while you check the formula in Excel. Follow the worked example and change one input at a time. The steps explain the workbook calculation; this page does not run a live calculator for that task.
Common mistakes
- Giving
INDEXandMATCHranges of different heights, so the row number fromMATCHpoints at the wrong cell. - Forgetting the 0 in
MATCH, which switches it to an approximate match and can return a wrong row. - Selecting the whole table for
INDEXinstead of a single return column, which forces a needless extra column-number argument.
Frequently asked questions
Why use INDEX/MATCH instead of VLOOKUP?
INDEX/MATCH can return columns to the left of the lookup column, and it keeps working when you insert or move columns because it references columns directly rather than by a counted index number.
What does the 0 in MATCH mean?
It requests an exact match. Without it, or with 1, MATCH does an approximate match that needs sorted data and can silently return the wrong position, so include 0 for normal lookups.
Is INDEX/MATCH faster than VLOOKUP?
On large sheets it can be, because it only scans the lookup column and the return column rather than the whole table array, though XLOOKUP is simpler still if your Excel version supports it.
What if I need to look up both a row and a column?
That is a two-way lookup: add a second MATCH for the column header and pass both positions to INDEX. The related INDEX MATCH MATCH guide works through a product-by-month matrix; multiple criteria on one row are a separate task.
