Форматирование (отступ 2 пробела), минификация и валидация JSON прямо в браузере.
Часто задаваемые вопросы
What is the difference between Format and Minify?
Format adds 2-space indentation for readability, while Minify strips all unnecessary whitespace and line breaks to shrink the file size. Both modes only reformat the structure — the actual characters inside string values are never touched.
Is it safe to paste data from a real project here?
Yes — formatting, minifying, and validation all happen entirely in your browser via JavaScript. Nothing is uploaded to any server.
Why does JSON that looks valid still fail validation?
The most common cause is a trailing comma before a closing bracket or brace. Some programming languages allow that, but the JSON standard does not, so the parser reports an error right at that spot.
