description: Translate HTML files with the General Translation CLI. API reference for the HTML file format.

---

The CLI translates HTML files. All syntax and formatting in the source files is preserved in the translated files.

## Configuration [#config]

Add an `html` entry under `files` with an `include` array of glob patterns. Use the `[locale]` placeholder so the CLI can find source files and save translations to the right path.

```json title="gt.config.json"
{
  "defaultLocale": "en",
  "locales": ["es", "fr"],
  "files": {
    "html": {
      "include": ["docs/[locale]/**/*.html"]
    }
  }
}
```

See the [configuration reference](/docs/cli/reference/config#files) for all file keys, including `transform` for renaming translated output.
