About this tool

Validates OpenAPI Specification (OAS) documents, supporting both Swagger 2.0 and OpenAPI 3.x versions. Users paste or upload their specification files into the tool's interface for automated checking. The validator analyzes the document structure to ensure compliance with industry standards, identifying issues related to schemas, defined paths, security requirements, and general best practices. It provides detailed feedback on structural inconsistencies and potential improvements needed before deployment. Developers and API designers use this utility to maintain the integrity of their service definitions. By catching validation errors early in the development lifecycle, it significantly reduces debugging time and prevents runtime failures caused by malformed specifications.

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.
