Frequently Asked Questions

Arrays of objects (e.g., [{name: 'A', value: 10}]) or objects with arrays (e.g., {names: ['A','B'], values: [10,20]}). The generator auto-detects structure and suggests data paths for mapping to chart axes.

After loading JSON, the tool displays detected data paths like 'data[].sales' or 'metrics.revenue[]'. Select which path to use for X-axis (categories or values) and Y-axis (numeric values). For nested objects, use dot notation.

Bar charts (vertical and horizontal), line charts, pie charts, and scatter plots. Each type suits different data: bars for comparisons, lines for trends, pies for proportions, scatter for correlations.

Yes—the generator supports nested objects and arrays. Use dot notation paths like 'results[].metrics.revenue' to access deeply nested values. Preview shows detected structure for easy mapping.

Export charts as PNG images (for presentations, documents, social media) or SVG vector files (for editing in Adobe Illustrator, Inkscape, or web use). PNG supports high resolution (2x pixel ratio).

ECharts handles thousands of data points efficiently. For very large datasets (100,000+ items), consider filtering or aggregating data first to improve browser performance and chart readability.

No—all JSON parsing and chart rendering happens in your browser using JavaScript. Your data never leaves your device, ensuring complete privacy for sensitive business or API data.

Yes—customize chart title, axis labels, and styling after data is loaded. ECharts provides interactive tooltips, zoom controls, and legend positioning automatically. Full customization options appear in the config panel.

The generator auto-detects data types for each path. Non-numeric values in numeric fields are ignored or treated as zero. Ensure numeric paths contain only numbers for accurate chart values.

Yes—use line charts with ISO 8601 date strings (e.g., '2024-01-15') or Unix timestamps on the X-axis. The generator recognizes common date formats. For best results, ensure consistent date formatting in your JSON.
