This interface defines a contract for text splitting services. The primary function is to take a single piece of text and split it into an array of substrings based on a specific implementation-defined criterion.\
Implementations of this interface may use different strategies for splitting, such as splitting by spaces, punctuation, or custom delimiters.

## Methods

### ![](/files/ptrKjmmRoQB76pvrIqh0) Split(text)

Splits the specified text into an array of substrings.

| Parameter | Type                                                          | Description                                                                    |
| --------- | ------------------------------------------------------------- | ------------------------------------------------------------------------------ |
| **text**  | [String](https://docs.microsoft.com/dotnet/api/system.string) | The text to split into substrings. This parameter should not be null or empty. |

**Returns:** [String\[\]](https://docs.microsoft.com/dotnet/api/system.string). An array of substrings derived from the *text* .

This method processes the input text according to the splitting logic defined by the implementation. The result is an array where each element is a substring of the original text.\
Example usage:

```csharp

  ITextSplitterService splitterService = new SimpleTextSplitterService();
  string[] words = splitterService.Split("This is a sample text.");
  // words: ["This", "is", "a", "sample", "text."]

```

* [ArgumentNullException](https://docs.microsoft.com/dotnet/api/system.argumentnullexception)\
  Thrown when the *text* is null.

| [RecursiveCharacterTextSplitterService](/ai/components/api/services/itextsplitterservice/wisej.ai.services.recursivecharactertextsplitterservice.md) | A service for recursively splitting text into chunks based on specified separators and chunk size constraints. This service attempts to split text by different characters to find an optimal separation strategy. |
| [TextSplitterServiceBase](/ai/components/api/services/itextsplitterservice/wisej.ai.services.textsplitterservicebase.md)                             | Provides the base functionality for text splitting services, allowing subclasses to define custom splitting logic.                                                                                                 |
