# I18n Formats

We work on extending the list of supported i18n formats. If you need an i18n format and can't find it here send us an [email](mailto:support@locize.com).

Depending on the format it comes with different support functionality helping you with correct syntax.

{% hint style="warning" %}
The chosen i18n format will always be respected. There is no sort of i18n format conversion while importing from or exporting to one of the supported [file formats](/integration/supported-formats.md).
{% endhint %}

{% hint style="info" %}
You can learn more about the different i18n formats [here](https://locize.com/blog/i18n-multiverse/).
