# Convert field type
The `convert` processor converts a field in the event to a different type, such as converting a string to an integer.
The supported types include: `integer`, `long`, `float`, `double`, `string`, `boolean`, and `ip`.
The `ip` type is effectively an alias for `string`, but with an added validation that the value is an IPv4 or IPv6 address.

## Example

```yaml
  - convert:
      fields:
        - {from: "src_ip", to: "source.ip", type: "ip"}
        - {from: "src_port", to: "source.port", type: "integer"}
      ignore_missing: true
      fail_on_error: false
```


## Configuration settings

<note>
  Elastic Agent processors execute *before* ingest pipelines, which means that your processor configurations cannot refer to fields that are created by ingest pipelines or Logstash. For more limitations, refer to [What are some limitations of using processors?](/elastic/docs-builder/docs/3016/reference/fleet/agent-processors#limitations)

| `fields`         | Yes      |         | List of fields to convert. The list must contain at least one item. Each item must have a `from` key that specifies the source field. The `to` key is optional and specifies where to assign the converted value. If `to` is omitted, the `from` field is updated in-place. The `type` key specifies the data type to convert the value to. If `type` is omitted, the processor copies or renames the field without any type conversion. |
| `ignore_missing` | No       | `false` | Whether to ignore missing `from` keys. If `true` and the `from` key is not found in the event, the processor continues to the next field. If `false`, the processor returns an error and does not process the remaining fields.                                                                                                                                                                                                          |
| `fail_on_error`  | No       | `true`  | Whether to fail when a type conversion error occurs. If `false`, type conversion failures are ignored, and the processor continues to the next field.                                                                                                                                                                                                                                                                                    |
| `tag`            | No       |         | Identifier for this processor. Useful for debugging.                                                                                                                                                                                                                                                                                                                                                                                     |
| `mode`           | No       | `copy`  | When both `from` and `to` are defined for a field, `mode` controls whether to `copy` or `rename` the field when the type conversion is successful.                                                                                                                                                                                                                                                                                       |
