Where can you download the JSON structure for your Receipt Processing app?

The JSON structure for your Receipt Processing app can be downloaded in the Document Model Training web app. This web app is specifically designed for training models related to document processing, including receipts. It provides the necessary tools and functionalities for downloading relevant files, such as the JSON structure, which is essential for defining the layout and fields for processing receipts. Utilizing the Document Model Training web app ensures you get the most accurate and up-to-date structure that aligns with the app's requirements.

Other options, while they may seem plausible, do not provide the specific resources needed for this task. The Mendix Marketplace typically offers various modules and components but does not focus specifically on training data structures. The App Store contains applications rather than the specific JSON structures for receipt processing. Similarly, the Settings menu deals with application configurations rather than the downloading of data structures. Therefore, the Document Model Training web app is the correct context for obtaining the desired JSON structure.
