What format does the Read API output for extracted text?

• A. XML format
• B. Plain text format
• C. HTML format
• D. JSON format

Answer: (D)

The Read API in Azure Computer Vision is designed to extract text from images and documents, returning the results in a structured manner that is easy to interpret programmatically. The correct output format for the extracted text is JSON format.

JSON (JavaScript Object Notation) is widely used in APIs because it is lightweight, easy for humans to read and write, and easy for machines to parse and generate. The output includes a structured representation of the extracted text, along with information such as the position and confidence level of the detected words, enabling developers to use this data effectively in their applications.

The other formats mentioned, such as XML, plain text, and HTML, do not provide the same level of structured data that JSON does, making JSON the more suitable and preferred choice for programmatically accessing the results of the Read API. JSON's flexibility allows for easy integration and manipulation of the extracted data within different applications and services.
