# `splitParts`

## Description

Splits a string using a delimiter and return the token at the specified index. The index starts at 1, not 0.

## Syntax

Like many functions in DataPrime, `splitParts` supports [two notations](https://coralogix.com/docs/dataprime/language-reference/functions-reference/index.md), **function** and **method** notation. These interchangeable forms allow flexibility in how you structure expressions.

```dataprime
splitParts(value: string, delimiter: string, index: number): string
```

```dataprime
(value: string).splitParts(delimiter: string, index: number): string
```

```

```dataprime
create domain from email.splitParts('@', 2)
