What file formats can I upload?

Excel workbooks (.xlsx, .xls, .xlsm), OpenDocument spreadsheets (.ods), and CSV, TSV or plain-text files. Files are read in your browser; for a workbook with several sheets you pick which one to chart.

Can I edit the chart after the AI generates it?

Absolutely. When the AI generates data, it lands in the data box where you can see and edit it, change the chart type, adjust colors, modify the title, and tweak every setting before downloading.

What chart types are supported?

We support 25 chart types: Column, Bar, Line, Area, Step Line, Pie, Doughnut, Rose, Scatter, Radar, Combo, Heatmap, Treemap, Sunburst, Funnel, Candlestick, Waterfall, Gauge, Box Plot, plus all Stacked and 100% Stacked variants for bars, columns, lines, and areas.

What image formats can I download charts in?

You can download charts as PNG (best for web and presentations), JPEG (smaller file size), or SVG (vector format, perfect for print and scaling). All exports are rendered at 2x resolution for crisp, professional output.

How do I format my CSV data?

Use a simple structure: first row is headers, first column is category labels (like months, products, regions), and the remaining columns are numeric values. Comma, tab, semicolon and pipe delimiters are detected automatically, and values like $1,200 or 45% are read as numbers. Text columns other than the first are skipped.

Can I use this for academic or professional publications?

Yes. Export as SVG for lossless vector graphics that scale perfectly in LaTeX, Word, and professional design tools. Use the Grayscale or Colorblind-safe palette for publication-standard accessibility.

Does the AI generate real data or placeholder data?

If you paste or upload real data, it is charted exactly as-is; the AI never changes it. If you only provide a text description, the AI generates realistic, plausible sample data that matches your description. You can always edit the data afterward.

What's the difference between this and Excel's built-in charts?

This tool is faster (no software to install), supports more chart types (like rose, treemap, sunburst, candlestick), has AI-powered data generation, and exports at the exact size you need. It's designed for quick, professional chart creation without the complexity of spreadsheet software.

Is my data stored or shared?

No. All chart rendering happens in your browser. Data you paste or upload never leaves your device unless you press one of the AI buttons. Then your description, or your data for Suggest chart with AI, is sent to the AI for processing and is not stored after the response is generated.

Tips for Creating Better Charts

✓
Choose the right chart type for your data
Use line charts for trends over time, bar charts for category comparisons, pie charts for part-to-whole (under 7 slices), scatter for correlations, and heatmaps for matrix data.
✓
Keep your data clean and structured
Use a clear header row with descriptive column names. Put categories in the first column and numeric values in the remaining columns. Remove totals and summary rows.
✓
Use the AI mode for quick prototyping
Describe what you want in plain English like 'quarterly revenue for 5 tech companies' and the AI will generate realistic sample data. You can then edit the generated data like any other.
✓
Customize colors for your audience
Use the Colorblind-safe palette for accessible publications. Use Pastel for light, friendly presentations. Use Grayscale for print-optimized black-and-white output.
✓
Export at the right size and format
Pick an export size that matches where the chart is going (16:9 slide, Full HD, square for social, or document). Use PNG for presentations and web, JPEG for smaller file sizes, and SVG for print and documents that need perfect scaling.

How to Use AI Chart Generation

Describe with AI lets you create charts without entering data by hand. Describe what you need, or upload a file and let AI pick the chart.

Generate from a text description›

Simply describe the chart you want in natural language. The AI generates realistic, plausible data and picks the best chart type automatically.

"Monthly website traffic for an e-commerce site showing visitors, page views, and bounce rate for 2024"

Use your own numbers in the description›

Mention the figures you already have and the AI builds the dataset around them instead of inventing values.

"Quarterly revenue: Q1 120k, Q2 135k, Q3 128k, Q4 160k, as a column chart"

Chart an Excel or CSV file›

Upload a spreadsheet or CSV file. Text columns become the labels and every numeric column becomes a series; pick the sheet if the workbook has several.

Upload a .csv export from Google Analytics or a .xlsx budget spreadsheet

Let AI pick the chart for your data›

Already have data in the box? Suggest chart with AI reads it and picks the chart type and a title that fit it best. You can still change both.

Paste monthly sales by region, then click Suggest chart with AI
