# Character Text Splitter - Workflow node | Docs - nodulz

Source: https://nodulz.com/docs/nodes/ai_character_text_splitter

Language: en

Split text by character count

## Usage and specifics

Splitting uses character size and overlap. Keep chunkOverlap below chunkSize to produce useful chunks.

Technical type : `ai_character_text_splitter`. Runtime : `nodulz`.

## Credentials and prerequisites

This node defines no dedicated external credential. Remote sources or execution targets may still need their own access credentials.

See the [credentials guide](/docs/credentials) if a remote source or execution target requires access.

## Parameters

Names below are technical keys. Defaults are not a ready-to-run configuration: complete fields required by your operation. Paths containing [] describe list items; some fields depend on the selected mode.

| Parameter | Type | Default | Values / limits |
| --- | --- | --- | --- |
| `source` | `string` | `""` | - |
| `chunkSize` | `number` | `1000` | -; ≥ 1 |
| `chunkOverlap` | `number` | `200` | -; ≥ 0 |
| `separators` | `string` | `"\\n\\n,\\n, ,"` | - |

## Initial configuration

Initial catalog configuration example, to adapt before running. Keep secrets in credentials.

```json
{
  "source": "",
  "chunkSize": 1000,
  "chunkOverlap": 200,
  "separators": "\\n\\n,\\n, ,"
}
```

## Verification

Test with representative data. Check node output in the inspector and logs, then use editor mapping for downstream fields. A trigger test with a simulated payload does not validate external service delivery.
