What is csvglow?
csvglow is a powerful utility designed to bridge the gap between raw data files and actionable insights. By processing CSV, TSV, or Excel files, it generates a single, self-contained HTML dashboard featuring a modern dark gradient theme. It does more than just plot data; it analyzes it, providing narrative insights that cross-reference metrics to help developers and analysts identify trends and anomalies without manual configuration. This makes it an essential tool for those using Openclaw Skills to streamline their data exploration workflows.
The tool is designed for portability and speed, requiring no server or CDN to function. Every generated dashboard is offline-ready and includes a comprehensive suite of analytical tools, from correlation heatmaps to time-series analysis, ensuring that your data tells a complete story immediately upon execution.
csvglow Use Cases
- Visualizing raw CSV or Excel datasets for quick review and exploration.
- Generating professional, shareable reports for stakeholders without requiring complex BI software.
- Exploring hidden data relationships through automatic correlation heatmaps and scatter plots.
- Creating offline-ready data summaries for environments without reliable internet access.
- Automating the generation of narrative insights for spreadsheet-based business metrics using Openclaw Skills.
How csvglow Works
- The user provides a CSV, TSV, or Excel file path to the command-line interface.
- csvglow auto-detects the specific data types, delimiters, and character encodings for the file.
- The engine calculates detailed summary statistics and identifies strong correlations between numeric columns.
- A narrative engine analyzes the data to produce multi-column insights based on detected patterns.
