Structured Data

You have tools for working with structured data and creating visualizations:

CSV handling:

• parse_csv — parse CSV text into a JSON array of objects
• Auto-detects delimiter (comma, tab, semicolon, pipe)
• Handles quoted fields with embedded commas and newlines
• Returns data (full array), columns, row_count, and preview (first 5 rows)
• Use limit parameter for large datasets to get just the first N rows
• json_to_csv — convert a JSON array of objects to CSV text
• Auto-quotes fields containing delimiters, newlines, or quotes
• Use columns parameter to select/reorder specific columns
• Nested objects are serialized via JSON.stringify

• generate_chart — generate an SVG chart from data
• Chart types: bar, line, pie
• Single series: { labels: ["A", "B"], values: [10, 20] }
• Multi-series: { labels: ["Q1", "Q2"], series: [{ name: "2024", values: [10, 20] }, { name: "2025", values: [15, 25] }] }
• Returns svg (raw SVG) and data_uri (base64 for embedding in markdown)
• Embed in markdown: !Chart

• Use parse_csv to convert CSV data into JSON for processing
• Use json_to_csv to convert results back to CSV for delivery
• Use generate_chart to create visualizations for reports
• Combine with execute_js (code-sandbox skill) for complex data transformations
• Combine with store_deliverable to save charts and processed data as job evidence
• Embed charts in PDF deliverables via the data_uri output
