Convert JSON to OPML

JSON, or JavaScript Object Notation, is a lightweight data interchange format widely used in modern web development for its simplicity and ease of parsing. Originating in the early 2000s, JSON provides a text-based way to represent structured data based on JavaScript object syntax. It has become a standard format for APIs and configuration files, enabling seamless data exchange between servers and web applications due to its human-readable and machine-friendly nature. JSON's adoption has been driven by its ability to facilitate efficient data serialization and deserialization, making it indispensable in the realm of web technologies.

OPML, or Outline Processor Markup Language, is a file format utilized primarily for outlining data structures. Initially developed in 2000 by UserLand Software, OPML was designed to facilitate the exchange of outline-based information between different software applications. Its uses have expanded over time, notably in organizing RSS feed lists and managing hierarchical data. The OPML file extension denotes XML-based documents that offer simplicity and interoperability in transferring structured information across diverse platforms. In essence, OPML serves as a versatile tool in the realm of data organization and syndication.
