## Why Use JSON to Chart?

Data visualization makes complex information easy to understand. This tool lets you quickly generate professional charts from structured JSON data, perfect for dashboards, reports, and presentations.

## Tips for Better Charts

- Keep data arrays under 20 items for readable bar and line charts. For larger datasets, group or aggregate values first.
- Use consistent color schemes across related charts. Add a 'color' hex value to each data point for brand-aligned visuals.
- Always include axis labels and a descriptive title so your chart makes sense without additional context.
- Choose pie charts only when showing parts of a whole with fewer than 7 slices. Too many slices become hard to read.
- Load the sample data first to understand the expected JSON structure, then replace it with your own values.

## Frequently Asked Questions

### What chart types are supported?

Currently supports bar charts, line charts, and pie charts. Set the 'type' property to 'bar', 'line', or 'pie'. Default is bar chart.

### How do I format the data?

Provide a 'data' array where each item has 'label' (string) and 'value' (number). Optionally add 'color' (hex) for custom colors per data point.

### Can I customize colors?

Yes! Add a 'color' property with a hex value to each data point. The tool also has a default color palette that cycles through attractive colors.

### How do I add a title and labels?

Add 'title' for the chart title, 'xAxisLabel' for horizontal axis label, and 'yAxisLabel' for vertical axis label to your JSON.

### Can I use this for dashboards?

Yes! Export the PNG for static dashboards or use the JSON structure as a starting point for dynamic chart libraries like Chart.js or Recharts.

### Does the JSON to Chart tool require a signup?

Available with no signup, no usage limits, and no watermarks on exported charts. Processing happens entirely in your browser.

### Is my data safe when generating charts?

Yes. All chart rendering happens client-side in your browser. Your JSON data is never uploaded to any server, making it safe for confidential business data.

### What resolution are the exported PNG images?

Charts export at the displayed resolution, typically suitable for presentations and web use. For higher resolution, increase your browser zoom before exporting.

### Can I generate multiple charts from nested JSON?

The tool expects a flat data array for each chart. For nested JSON, use the JSON Path Finder or JSON Formatter to extract the specific array you want to visualize, then paste it here.

### How does this compare to Google Sheets charts?

Google Sheets requires uploading data and having an account. This tool works instantly with JSON data in your browser with no account needed. It is ideal for developers who already work with JSON and need a quick visualization without switching to a spreadsheet.
