How this tool runs
There is no server-side version of this tool, so there is no choice to make and nothing to send.
In 2025 two of the largest JSON formatting sites were found to have kept five years of everything their users pasted, including bank Active Directory credentials and cloud access keys, because a save-and-share feature quietly stored it all. This one parses in your browser. There is no save, no share link and no server to store anything on.
