# Split

Returns one of the components of a field's string output after splitting it with a delimiter. Common use cases for this method include discarding unwanted data from a field's output, and splitting output from one field into separate fields.

## Parameters

The following parameters are in the computed field's [global Method](/senseml-reference/computed-field-methods/index-computed-field-methods#parameters) parameter:

| key                       | value                            | description                                                                                                                    |
| ------------------------- | -------------------------------- | ------------------------------------------------------------------------------------------------------------------------------ |
| id (**required**)         | split                            |                                                                                                                                |
| source\_id (**required**) | a field id in the current config | The id of the field to split into substrings.                                                                                  |
| separator (**required**)  | string                           | The separator to use in the split.                                                                                             |
| index                     | integer                          | The zero-based index of the substring to return after the split. If unspecified, returns all the split substrings as an array. |

## Examples

The following example shows splitting a field's output to extract a first and last name.

**Config**

```JSON JSON 
{
  "fields": [
    {
      "id": "_driver_name_raw",
      "anchor": "name of driver",
      "method": {
        "id": "label",
        "position": "below"
      }
    }
  ],
  "computed_fields": [
    {
      "id": "driver_name_last",
      "method": {
        "id": "split",
        "source_id": "_driver_name_raw",
        "separator": " ",
        "index": 1
      }
    },
    {
      "id": "driver_name_first",
      "method": {
        "id": "split",

      }
    }
