Why convert JSON to HTML?
JSON is a structured text format widely used by APIs, applications, and development tools. Converting it to HTML creates a web document containing structured page content that browsers can display, ready for workflows that use the destination format.
HTML opens in every web browser and can be edited in any text editor, code editor, or website tool.
