Adobe Target primarily deals with personalization and A/B testing for web experiences. Uploading and publishing multiple file formats like .json, .pdf, and .gif directly in Adobe Target might not be a typical use case, as Adobe Target is more focused on delivering personalized content and experiences rather than hosting files. Define audiences in Adobe Target based on certain criteria. For example, you might have different audiences for users interested in .pdf content, .json content, or .gif content.
