What This Skill Does

The data-analysis-pro skill is a sophisticated tool designed to bridge the gap between raw datasets and actionable insights using natural language. By leveraging the ChartGen API, this skill allows OpenClaw users to perform complex data operations without writing SQL or Python code. It automatically interprets conversational queries, parses metrics and dimensions, and executes professional-grade analytics. The tool covers three major pillars: Data Analysis (statistics, filtering, and aggregation), Data Interpretation (trend detection and report generation), and Data Visualization (automated chart creation). Whether you are managing sales metrics or exploring JSON-based datasets, this skill provides a seamless interface to transform files into structured, interactive BI reports.

Installation

To integrate this skill into your environment, ensure you have the OpenClaw agent installed. Run the following command in your terminal: clawhub install openclaw/skills/skills/chartgen-ai/data-analysis-pro. After installation, you must obtain an API key from chartgen.ai and export it as an environment variable by running export CHARTGEN_API_KEY="your-api-key-here". Without this configuration, the skill will be unable to communicate with the processing engine.

Use Cases

This skill is highly versatile and serves several professional workflows. For financial analysts, it enables quick calculation of year-over-year growth and total sales aggregation. Marketing teams can use it to interpret customer behavior trends from raw CSV exports, while product managers can utilize it to generate dynamic charts for stakeholder presentations. By supporting both Excel files and direct JSON input, the skill fits into automated data pipelines, allowing you to feed output from other agents directly into data-analysis-pro for final visualization and reporting.

Example Prompts

"Analyze the attached quarterly_sales.xlsx and provide a summary of the top three performing regions, including their total revenue growth compared to the previous quarter."
"Generate a bar chart showing the monthly active users from the provided user_data.json and highlight any significant downward trends."
"Filter the dataset to include only transactions above $500 and calculate the average transaction value for the electronics category."

Tips & Limitations

To maximize performance, ensure your CSV or Excel files are formatted with clear, single-row headers. The skill works best with standardized, clean data. Keep in mind that each query consumes 20 credits, so complex requests should be consolidated where possible. If the skill fails to interpret a query, try using more specific keywords like 'sum', 'filter', or 'trend'. Currently, the skill requires an active internet connection to access the ChartGen API and does not support real-time data streaming; it operates strictly on static file uploads or direct data input.
