Localization

The Localization package extends Unity's built-in localization and remains a complete localization system for projects that have not moved to it.

Unity itself provides string and asset tables, Smart Strings, locale management, and JSON import and export. This package adds:

• CSV and XLIFF import and export in the Resource Tables window.

• An upgrade wizard that converts your table collections and components to the built-in system, with a redirect layer that keeps existing scripts working.

• Addressables support, so localized content loads on demand and can ship separately, for example as language packs.

• Google Sheets synchronization for working with translators.

• Property variants, to edit component properties per locale in the Inspector.

• Pseudo-localization, to test layout before translations arrive.

Projects that have not upgraded keep the package's full workflow: string localization with Smart Strings, asset localization, and import and export of localization data.

Core packages are fixed to a single version matching the Editor version.
