About AI Data Visualizer (Paste CSV)
The AI Data Visualizer turns a table into a chart and tells you what it shows. Paste CSV or cells from Excel or Google Sheets, or upload a file, and a chart appears instantly. Restyle it and download it as a PNG, free. When you want the story behind the numbers, Analyze with AI recommends the best chart, writes a title and axis labels, and lists the key insights, every number checked against your data.
What you get
- An instant chart, free. Bar, horizontal bar, line, area, pie or doughnut, drawn in your browser the moment you paste.
- Full control. Pick the label column and series, sort, keep the top values, choose colors, show value labels, set the title.
- Your numbers, untouched. Code reads every value. The AI never retypes your data.
- Insights you can trust. The AI writes from statistics computed by code: totals, averages, highs and lows, changes, shares and outliers. Any sentence with a number that isn't in your data is removed.
- Report-ready. A short summary paragraph, a title and axis labels, and a PNG of the chart.
How to use it
- Paste your table with a header row, or upload a .csv, .tsv or .xlsx file.
- Adjust the chart: type, label column, series, sorting, top values and colors.
- Optionally describe the data, then click Analyze with AI.
- Apply the recommended chart, copy the insights and summary, and download the PNG.
Choosing the right chart
| Your data | Best chart |
|---|---|
| Values over time (days, months, years) | Line or area |
| Comparing a handful of categories | Bar |
| Many categories or long names | Horizontal bar, sorted largest first |
| Parts of a whole, up to about 8 parts | Pie or doughnut |
| Two or more measures per category | Grouped bar or multi-line |
Formatting tips
- Put the labels (months, names, categories) in the first column and one measure per column after it.
- Keep a single header row at the top.
- Numbers can include currency symbols, thousands separators and percent signs.

Frequently asked questions
How do I make a chart from CSV data?
Paste your data (with a header row) into the box, or upload a .csv or .xlsx file. The chart appears instantly. Choose the chart type, the label column and which series to show, sort it or keep only the top values, then download it as a PNG. Making and changing the chart is free and doesn't use a credit.
What does the AI analysis add?
Click Analyze with AI and it recommends the best chart type for your data with a reason, writes a title and axis labels, lists 3 to 5 key insights (trends, peaks, lows, changes, concentration and outliers) and writes a short summary you can paste into a report. It uses one AI credit.
Can the AI change or make up my numbers?
No. Your numbers are read by code, never retyped by the AI. The AI only sees statistics that code computed from your data, and any insight that quotes a number that isn't in your data or those statistics is removed before you see it.
Can I paste data from Excel or Google Sheets?
Yes. Copy the cells, including the header row, and paste them; tab-separated data is detected automatically. You can also upload an .xlsx file. Currency symbols, thousands separators and percentages are understood.
Which chart should I use?
Use a line or area chart for values over time, a bar chart to compare categories, a horizontal bar chart when there are many categories or long names, and a pie or doughnut chart only for parts of a whole with a few categories. The AI analysis recommends one for your data.
Is my data private?
The chart is drawn entirely in your browser. Only when you click Analyze with AI is the data sent to the server to compute statistics and write the insights.
