title: FileToTranslate (legacy)
description: Review the legacy file input removed from Core v9 and its current replacement. API reference for FileToTranslate.

---

`FileToTranslate` represented a file object in Core 8.x batch translation workflows. It is not exported by `generaltranslation` 9.x.

<Callout type="info">
  **Changed in v9:** `FileToTranslate` was removed. Use `FileToUpload` for [`uploadSourceFiles`](/docs/platform/core/reference/gt-class-methods/translation/upload-source-files), then pass the returned file references to [`enqueueFiles`](/docs/platform/core/reference/gt-class-methods/translation/enqueue-files).
</Callout>

## Overview [#overview]

The legacy type bundled a file's raw content, name, and format:

```typescript
type FileToTranslate = {
  content: string;
  fileName: string;
  fileFormat: FileFormat;
  formatMetadata?: Record<string, any>;
  dataFormat?: DataFormat;
};
```

| [`fileFormat`](#file-format) | Legacy file-format identifier. | string union | No |
| [`formatMetadata`](#format-metadata) | Format-specific metadata. | `Record<string, any>` | Yes |

## Legacy example [#legacy-example]

```typescript
// generaltranslation 8.x only
import type { FileToTranslate } from 'generaltranslation';

// JSON file
const jsonFile: FileToTranslate = {
  content: JSON.stringify({
    "welcome": "Welcome",
    "save": "Save"
  }),
  fileName: 'common.json',
  fileFormat: 'JSON',
  dataFormat: 'I18NEXT'
};
```

```typescript
// MDX file
const mdxFile: FileToTranslate = {
  content: `# Getting Started\n\nWelcome to our platform!`,
  fileName: 'docs/start.mdx',
  fileFormat: 'MDX',
  dataFormat: 'JSX'
};
```

## Current replacement [#replacement]

In 9.x, import `FileToUpload` from `generaltranslation/types`, upload the source, and use the returned reference for later operations:

```typescript
import { GT } from 'generaltranslation';
import type { FileToUpload } from 'generaltranslation/types';

const gt = new GT({
  apiKey: process.env.GT_API_KEY,
  projectId: process.env.GT_PROJECT_ID,
});

const source = {
  content: JSON.stringify({ welcome: 'Welcome' }),
  fileName: 'common.json',
  fileFormat: 'JSON',
  locale: 'en',
} satisfies FileToUpload;

const { uploadedFiles } = await gt.uploadSourceFiles(
  [{ source }],
  { sourceLocale: 'en' }
);
```
