<p>For a pre-built JSON file of a flow that uses the Google Drive loader component, download the <a href="./files/Google_Drive_Docs_Translations_Example.json" download="">Google Drive Document Translation Example Flow JSON</a> to your local machine.</p>
|
||
<p>In this example, the <strong>Google Drive loader</strong> component loads a text file hosted on Google Drive, translates the text to Spanish, and returns it to a chat output.</p>

<ol>
|
||
<li>Download the <a href="./files/Google_Drive_Docs_Translations_Example.json" download="">Google Drive Document Translation Example Flow JSON</a> to your local machine.</li>
|

<li>To import the downloaded JSON to Langflow, click <strong>Options</strong>, and then select <strong>Import</strong>.</li>
|
||
<li>In the <strong>Credentials File</strong> field of the Google OAuth Token component, enter the path to your <strong>Credentials File</strong>, the JSON file containing the Client ID credentials you downloaded from Google in the previous steps.</li>
|

<li>In the Google Drive loader component, in the <code>JSON String of the Service Account Token</code> field, enter the JSON string containing the token returned in the output of the Google OAuth Token component.</li>
|

</ol>

<p>The example flow includes a <strong>Parse data</strong> component to convert the <code>data</code> output of the Google OAuth Token component to the <code>text</code> input of the JSON Cleaner component.</p>

<li>To allow the Langflow component to access the file in Google Drive, copy the Google Drive File ID from the document's URL.</li>
