# purchase.address-autocomplete.format-suggestion

  An extension target that formats the selected address suggestion provided by a [`purchase.address-autocomplete.suggest`](/docs/api/checkout-ui-extensions/2024-04/targets/address/purchase-address-autocomplete-suggest) target. This formatted address is used to auto-populate the fields of the address form.

  It must return a [`formattedAddress`](/docs/api/checkout-ui-extensions/2024-04/targets/address/purchase-address-autocomplete-format-suggestion#addressautocompleteformatsuggestionoutput-propertydetail-formattedaddress).

  > Caution:
  > This extension target is only necessary if the corresponding [`purchase.address-autocomplete.suggest`](/docs/api/checkout-ui-extensions/2024-04/targets/address/purchase-address-autocomplete-suggest) target does not provide a `formattedAddress` for the suggestions. If a formatted address is provided with each suggestion, then this target will not be called.
  >
  > If the [`purchase.address-autocomplete.suggest`](/docs/api/checkout-ui-extensions/2024-04/targets/address/purchase-address-autocomplete-suggest) target is not implemented, then this target will not work.

  > Note:
  > - This target does not support rendering UI components.
  > - This extension can only be developed as a JavaScript extension using the `ui-extensions` library.
  > - The [app extension configuration](/docs/apps/app-extensions/configuration) `shopify.extension.toml` file is shared between this extension target and [`purchase.address-autocomplete.suggest`](/docs/api/checkout-ui-extensions/2024-04/targets/address/purchase-address-autocomplete-suggest). This includes extension settings specified in the configuration file.

### capabilities
The allowed capabilities of the extension, defined in your [shopify.extension.toml](/docs/api/checkout-ui-extensions/configuration) file.

* [`api_access`](/docs/api/checkout-ui-extensions/configuration#api-access): the extension can access the Storefront API.

* [`network_access`](/docs/api/checkout-ui-extensions/configuration#network-access): the extension can make external network calls.

* [`block_progress`](/docs/api/checkout-ui-extensions/configuration#block-progress): the extension can block a customer's progress and the merchant has allowed this blocking behavior.

Shopify might render your extension before it's visible in the UI, typically to pre-render extensions that will appear on a later step of the checkout.

Your extension might also continue to run after the customer has navigated away from where it was rendered. The extension continues running so that your extension is immediately available to render if the customer navigates back.

If the extension is not capable of rendering UI components, then the value will always be false.

### target

### Editor

### type
Indicates whether the extension is rendering in the checkout editor.
### I18n

### formatCurrency
Returns a localized currency value.

This function behaves like the standard `Intl.NumberFormat()` with a style of `currency` applied. It uses the buyer's locale by default.
### formatDate
Returns a localized date value.

This function behaves like the standard `Intl.DateTimeFormatOptions()` and uses the buyer's locale by default. Formatting options can be passed in as options.
### formatNumber
Returns a localized number.

This function behaves like the standard `Intl.NumberFormat()` with a style of `decimal` applied. It uses the buyer's locale by default.
### translate
Returns translated content in the buyer's locale, as supported by the extension.

- `options.count` is a special numeric value used in pluralization.
- The other option keys and values are treated as replacements for interpolation.
- If the replacements are all primitives, then `translate()` returns a single string.
- If replacements contain UI components, then `translate()` returns an array of elements.
### I18nTranslate
This returns a translated string matching a key in a locale file.
export interface I18nTranslate {
  <ReplacementType = string>(
    key: string,
    options?: Record<string, ReplacementType | string | number>,
  ): ReplacementType extends string | number
    ? string
    : (string | ReplacementType)[];
}
### Localization

### country
The country context of the checkout. This value carries over from the context of the cart, where it was used to contextualize the storefront experience. If the country is unknown, then the value is undefined.
### currency
The currency that the customer sees for money amounts in the checkout.
### extensionLanguage
This is the customer's language, as supported by the extension. If the customer's actual language is not supported by the extension, then this is the language that is used for translations.

For example, if the customer's language is 'fr-CA' but your extension only supports translations for 'fr', then the `isoCode` for this language is 'fr'. If your extension does not provide french translations at all, then this value is the default locale for your extension (that is, the one matching your .default.json file).
### language
The language the customer sees in the checkout.
### market
The [market](/docs/apps/markets) context of the checkout. This value carries over from the context of the cart, where it was used to contextualize the storefront experience. If the market is unknown, then the value is undefined.
### timezone
The buyer’s time zone.
### Country

### isoCode
The ISO-3166-1 code for this country.
### Currency

### isoCode
The ISO-4217 code for this currency.
