Tentang JSON Formatter
A single misplaced comma can break a 2,000-line config file. Paste any JSON here to pretty-print it with your preferred indent, minify it for production, or validate it with error reporting that points to the exact line and column of the problem. The formatter handles large payloads, preserves your data exactly, and includes a key-sorting option for diff-friendly output — all locally in your browser.
