About this tool

Converts structured data between JavaScript Object Notation (JSON) and YAML Ain't Markup Language (YAML). The tool parses input from one format and outputs an equivalent representation in the other, maintaining structural integrity across both standards. Users simply paste their data into either designated area, and the converter automatically generates the corresponding output in the opposite format. This process ensures accurate translation between the two popular data serialization formats. Professionals working with configuration files frequently utilize this utility. Developers building infrastructure or automating pipelines often encounter scenarios where one system requires JSON while another mandates YAML for compatibility.

HTML Entity Encoder3 options

Developers and web designers often need to convert special characters into their corresponding HTML entities to ensure proper rendering across different browsers. HTML Entity Encoder provides a reliable method to transform sensitive characters—such as angle brackets, ampersands, and quotes—into standardized code that prevents browsers from misinterpreting them as functional HTML tags. This process is essential for anyone looking to display raw code snippets on a webpage or securely manage user input within a web application. The utility also integrates XSS prevention analysis, offering insights into how specific encoding choices contribute to site security. By substituting potentially malicious characters with safe entities, it helps mitigate the risk of cross-site scripting attacks that target vulnerabilities in data handling. Users can switch between encoding and decoding functions to verify their data or restore entities to their original plaintext format for editing and review.
