Common Questions
What is JSON?
JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and for machines to parse and generate.
Why do I need to format JSON?
Raw JSON from APIs often comes as a single line, making it hard to read. Formatting adds indentation and line breaks, making the structure clear.
