Frequently Asked Questions
- Which config files work with this tool?
- Any JSON configuration file: package.json, tsconfig.json, .eslintrc.json, babel.config.json, VS Code settings, AWS CloudFormation templates, and more.
- What is the difference between URL encoding and URI encoding?
- They are essentially the same concept. encodeURIComponent() (used here) encodes all characters except letters, digits, and - _ . ! ~ * ' ( ). Use it for individual URL components like query values.
About This Tool
Configuration files are at the heart of modern software development — from package.json and tsconfig.json to VS Code settings and cloud infrastructure templates. This URL Encoder for Config Files is tailored for processing URL configuration files with the precision and care they require. Configuration files often contain comments (in formats that support them), version-specific settings, and carefully structured hierarchies that must be preserved during formatting. The tool processes these files while maintaining all data integrity, ensuring that indentation reveals the logical structure of configuration sections, nested settings, and conditional values. Whether you are cleaning up auto-generated configuration, merging settings from multiple sources, or preparing config files for documentation, this tool handles the task reliably.
What is URL Encoder / Decoder?
A URL encoder/decoder converts text to and from percent-encoding (also called URL encoding), which is the format required for safely including special characters in URLs. Characters outside the unreserved set (letters, digits, -, _, ., ~) must be percent-encoded using their hexadecimal code points prefixed by %. For example, a space becomes %20, & becomes %26, and = becomes %3D. URL encoding is essential when constructing query strings, embedding user input in URLs, working with REST API endpoints that accept special characters in parameters, encoding redirect URLs, and processing form data submitted via HTTP GET requests. The decoder reverses the process, converting %XX sequences back to their original characters.
How to Use This Tool
