# MATCH function

## Description

Searches a value in a Dimension List property, either unique or non-unique, and returns the first item matching the value and `BLANK` if none is found.

> Unlike the MATCH function in Excel, the MATCH function in Pigment is **case sensitive**.
> 
> The following functions work effectively with MATCH:
> 
> - **LOWER**. Convert a Text value to lowercase. For more information, see [LOWER Function](/v1/docs/lower-function).
> - **TRIM**. Removes leading and trailing spaces and replaces multiple spaces between words with a single space. For more information, see [TRIM Function](/v1/docs/trim-function).
> 
> Here's how you'd use the LOWER and TRIM functions with MATCH:
> 
> `MATCH(TRIM(LOWER(Load.Email)), TRIM(LOWER(Dimension.Email)))`

## Syntax

`MATCH(Value to Match, Expression)`

- `Value to Match` can be any expression, that is, a string, number, Metric, List, or List Property. It can be made up of the following data types: `text`, `number`, `integer`, or `Dimension`.
- `Expression` can be a Metric, List, or List Property, and doesn’t need to contain unique values. If `Expression` is a Metric, then it needs to be defined on only a single list in the Metric structure.
- `Expression` and `Value to Match` need to be the same data types.
- The order for the first match found for `ValueToMatch` is determined by the ordering of the items in the `Expression`.

## Returns

| Type | Output Structure (Dimensions) |
| --- | --- |
| Dimension (same as `Expression`) | Same as `Value to Match` (if any exists, else will return Dimension Item of `Expression`) |

## Examples

| **Case** | **Results** | **Return Type** |
| --- | --- | --- |
| `MATCH("john@corp.com", 'Employees'.'Email')` | Returns "John H.", item of the `Employees` List. This is returned because it’s the first match found in the employee email list. | `Employee (Dimension)` |
| `MATCH("unknown@corp.com", 'Employees'.'Email')` | Returns `blank` if the email is not recognized in the List. | `Employee (Dimension)` |
| `MATCH(City.'Duplicate countries',Country.Name)` | For each row of the `Duplicate Countries` text property in the `City` List, it looks for the first matching country by name in the `Country` List, and then returns the first match found as an item of `Country`. | `Country (Dimension)` |

**Excel equivalent**: Similar to VLOOKUP, where [range_lookup] is FALSE
