# locale

The `locale` option of an extract field.

A BCP-47 locale such as `tr` that sets the decimal, thousands and date defaults for parsing. Kaabist does not guess it; lint warns `W005` when a numeric sample is ambiguous without it.

Type: `string`

## Example

```json
{
  "amount": {
    "selector": "td[data-col=amount]",
    "type": "money",
    "locale": "tr"
  }
}
```

From the contract fixture `login-2fa-checkpoint-report`, a program the test suite validates.
