# substringEvery

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

## substringEvery(text: String, amount: Number): Array<String>

Splits a string into an array of substrings equal to a specified length.

The last substring can be shorter than that length. If the length is greater than or equal to the
length of the string to split, the function returns the entire string.

_Introduced in DataWeave version 2.4.0._

### Parameters

<table><colgroup><col> <col></colgroup><thead><tr><th>Name</th><th>Description</th></tr></thead><tbody><tr><td><p><code>text</code></p></td><td><p>The string to split.</p></td></tr><tr><td><p><code>amount</code></p></td><td><p>The desired length of each substring.</p></td></tr></tbody></table>

### Example

This example shows how `substringEvery` behaves when splitting an input string. The last returned
substring is shorter than the others.

#### Source

```DataWeave
%dw 2.0
import substringEvery from dw::core::Strings
output application/json
---
substringEvery("substringEvery", 3)
```

#### Output

```Json
["sub", "str", "ing", "Eve", "ry"]
```

## substringEvery(text: Null, amount: Any): Null
