Why format your CSP?
Content Security Policy (CSP) strings can quickly become very long and difficult to read, especially on complex sites with many third-party integrations (analytics, ads, fonts, widgets).
Because a CSP is sent as a single HTTP header, it is usually minified into one long continuous string separated by semicolons. When debugging XSS issues or auditing a policy, formatting the string into multiple lines (one directive per block) makes it significantly easier for developers to comprehend.
