What is Data Format Encoder?
The Data Format Encoder is a versatile text conversion utility designed to assist developers and autonomous agents in converting strings between various encoding formats commonly used in modern web development, API communication, and low-level data processing. By leveraging this tool inside Openclaw Skills, your AI agents can seamlessly perform bidirectional base64 encoding and decoding, safe URL percent-encoding, HTML entity escaping to prevent cross-site scripting (XSS) vulnerabilities, and JSON character escaping for nested string handling.
In addition to standard web standards, this skill supports low-level formats such as hexadecimal byte representation, binary conversion, Unicode escape sequences, and ROT13 text obfuscation. Utilizing Openclaw Skills for data format conversion ensures that your workflow automated agents can process raw network payloads, construct clean API requests, and safely parse external data structures without needing locally executed scripts.
Data Format Encoder Use Cases
- Convert binary files or image buffers to base64 strings for direct API transmissions or inline data URL creation.
- Escape unsafe characters in URLs using percent-encoding before appending query strings or parameters to external requests.
- Protect web pages and sanitize user-generated inputs by converting active HTML scripts into safe HTML entities.
- Format raw text for embedding inside JSON structures by escaping tabs, double quotes, and line breaks.
- Inspect raw bytes or translate text into space-separated binary and hexadecimal strings for debugging or cryptographic use.
How Data Format Encoder Works
- Trigger Action: The AI agent selects the appropriate encoder action (such as encode-base64-encode or encode-url-encode) based on the target system requirements.
- Provide Input Payload: The agent supplies the target string inside the text parameter in a structured JSON payload.
- Validation & Conversion: The Openclaw Skills runner validates the parameters and uses UTF-8 encoding to execute the transformation rules requested (e.g., converting 'Hello' to '48656c6c6f' via hex translation).
- Receive Structured Output: The tool returns the transformed string value alongside size metadata, allowing the agent to safely use the encoded text in subsequent downstream tasks.
Data Format Encoder Setup
To enable this skill, you first need to connect your main AgentPMT account via the core setup skills. You can install the required dependencies using the following commands:
npx skills add AgentPMT/agent-skills --skill what-is-agentpmt
npx skills add AgentPMT/agent-skills --skill agentpmt-account-mcp-rest-api-setup
Once setup is complete, you can invoke the Data Format Encoder via the Openclaw Skills framework by specifying the product slug data-format-encoder and the corresponding action.
Data Format Encoder Data Schema & Taxonomy
The Data Format Encoder defines a consistent data structure across 15 actions. Every request requires a text parameter, and actions return structured JSON objects containing the transformed string.
Core Actions & Parameters
| Action Slug | Description | Required Parameter | Example Input | Example Output |
|---|---|---|---|---|
encode-base64-encode |
Encode plain text to Base64 | text (string) |
"Hello world!" |
"SGVsbG8gd29ybGQh" |
encode-base64-decode |
Decode Base64 string to plain text | text (string) |
"SGVsbG8gd29ybGQh" |
"Hello world!" |
encode-url-encode |
Percent-encode text for URLs | text (string) |
"hello world & goodbye" |
"hello%20world%20%26%20goodbye" |
encode-url-decode |
Decode percent-encoded text | text (string) |
"hello%20world%20%26%20goodbye" |
"hello world & goodbye" |
encode-html-entity-encode |
Escape special characters to HTML | text (string) |
"<div class=\"main\">Hello</div>" |
"<div class="main">Hello</div>" |
encode-escape-json |
Escape special characters for JSON | text (string) |
"Line 1\nLine 2" |
"Line 1\\nLine 2" |
encode-text-to-hex |
Convert text to hex representation | text (string) |
"Hello" |
"48656c6c6f" |
encode-hex-to-text |
Convert hex to plain text | text (string) |
"48 65 6c 6c 6f" |
"Hello" |
encode-rot13-encode |
Apply ROT13 substitution | text (string) |
"Hello World" |
"Uryyb Jbeyq" |
Data Format Encoder Advanced Features
- Flexible Hex Cleaning: Hex decoding actions automatically strip spacing characters like colons, hyphens, and spaces, permitting standard raw formats like
48:65:6c:6c:6fdirectly. - UTF-8 Standards Compliance: All transformations natively support UTF-8 encoding patterns, ensuring that complex multi-byte characters do not break under URL, base64, or JSON transformations.
- Inverse ROT13 Execution: Simple obfuscation handling is streamlined; applying
encode-rot13-encodetwice automatically acts as the decoder without requiring a separate decryption action. - Integrated Discovery Schema: Easily query live formatting instructions using
get_schemaandget_instructionsvia the main AgentPMT MCP server to sync action changes in real time.
