Use a third-party translation tool: There are several online translation tools, such as SDL Trados, that can help you translate your InDesign file into another language. Simply upload your file to the website and select the language you want to translate it to.
Hire a professional translator: If you want the highest quality translation, you can hire a professional translator to translate your InDesign file for you. They will have the expertise to translate not just the language but also the context and tone of the document.
Use a plugin like Adobe InCopy, it allows you to translate your text inside InDesign document using the standard translation memory and term base technology.
Another option is to export your InDesign file as an XML or IDML file, then use a CAT tool (Computer-assisted translation) to extract the text and translate it, then re-import the translated text.
