No email address, no password, no social media login, no "sign up to continue" popups. You open the page, use the tool, and you are done. Your privacy is protected because we never collect personal information — there is no account to create, no profile to manage, and no marketing emails to unsubscribe from. This makes our CSV to JSON ideal for quick one-time tasks and for users who value their privacy.
