First, go to the Google Translate website or open the Google Translate app. In the text box, you can copy and paste your entire document. Google Translate can handle translating large amounts of text, up to 5,000 characters at a time.
Once you have pasted the text, select the source language and the target language you want to translate to. Then, click the Translate button, and Google Translate will provide you with the translated text. You can review the translation section by section and make any necessary adjustments. Additionally, you can use the Back and Forward buttons at the bottom of the page to navigate through the translated text.
