Supported Formats

JSON Escape/Unescape: Safely adds or removes backslashes for newlines, quotes, and control characters so strings can be used inside JSON payloads.
HTML Entities: Converts special characters like < and > into safe HTML entities like < to prevent cross-site scripting (XSS) rendering issues.
URL Encode/Decode: Safely encodes strings to be passed as query parameters in URLs (converting spaces to %20, etc).
