file-converter

What This Skill Does

The file-converter skill is a robust, local-first utility designed to streamline data transformation and code formatting tasks directly within your terminal environment. It acts as a swiss-army knife for developers and data analysts who frequently handle various structured data formats. The skill provides a clean, command-line interface to perform essential operations such as pretty-printing and minifying JSON data, encoding and decoding URLs, generating hex dumps, and detecting file types. Beyond basic formatting, it facilitates the conversion between common formats, ensuring data interoperability. Because it runs locally using standard Unix tools like sed, awk, and grep, it provides a high-performance, privacy-conscious solution that ensures your sensitive data never leaves your machine for processing. Whether you are debugging an API response or preparing configuration files for deployment, this skill ensures consistency and readability.

Installation

To integrate this utility into your OpenClaw environment, execute the following command in your terminal: clawhub install openclaw/skills/skills/ckchzh/file-converter Once installed, you can configure the data directory by setting the FILE_CONVERTER_DIR environment variable, though it defaults to ~/.file-converter/ automatically. Ensure you have bash 4.0 or higher installed to utilize all feature sets.

Use Cases

• Debugging API Responses: Use the pretty-json command to quickly format bulky, minified JSON responses from web APIs into a readable structure.
• Data Pipeline Preparation: Convert and sanitize data files between YAML and JSON for configuration management or CI/CD pipelines.
• System Forensics: Utilize the hex dump functionality to inspect binary file contents for troubleshooting or verifying file integrity.
• Web Development: Quickly encode or decode URLs to clean up strings or prepare parameters for HTTP requests.

Example Prompts

1. "Pretty print the content of my current API response file using file-converter."
2. "Can you detect the format of the file named data.bin and show me its file statistics?"
3. "Please convert the provided JSON block into a minified version to save space in my configuration file."

Tips & Limitations

To get the most out of file-converter, ensure your environment has the necessary standard Unix utilities installed, as the script relies heavily on grep, sed, and awk. While it excels at structure and formatting, remember that it is a local tool; large file processing may impact system resources, so monitor your performance on particularly massive datasets. If you encounter issues, verify your shell version and ensure the FILE_CONVERTER_DIR has sufficient write permissions.
