How to make a chart from a CSV file
- Open your file: CSV, Excel or JSON, or try the sample sales data.
- Pick a chart type. A chart is suggested from your data: a line chart by month if there is a date column, otherwise a bar chart.
- Choose the category and the values. Rows with the same category are combined using the aggregate you choose, so you can chart total revenue per region straight from a list of orders without making a summary first.
- Add a title, pick colours and download the chart as PNG (at double resolution, sharp on slides) or SVG (scales to any size, editable in Figma, Illustrator or Inkscape).
Which chart should I use?
| Chart | Best for |
|---|---|
| Bar | Comparing amounts across categories: sales by region, tickets by team. Use horizontal bars when labels are long. |
| Stacked bar | Totals per category and what they are made of, using “Split by” or several value columns. |
| Line / area | Change over time. Group dates by month or quarter to smooth out daily noise. |
| Pie / donut | Shares of a whole, with only a few categories. Use “Top 8” to group the rest as “Other”. |
| Scatter | The relationship between two numbers, such as price and quantity. The trend line shows the correlation (r) and R². |
| Histogram | How the values of one numeric column are distributed: typical range, skew and outliers. |

Frequently asked questions
How do I make a graph from a CSV file?
Open the CSV on this page, choose a chart type, a category column and a value column. The chart appears instantly, and you can download it as PNG or SVG.
Can I make a chart from Excel data?
Yes. Open the .xlsx, .xls or .ods file directly and pick the sheet; there is no need to convert it to CSV first.
Do I need to summarise my data first?
No. If several rows share a category, they are combined with the aggregate you choose (sum, average, count, min or max). A list of orders becomes revenue per region in one step.
Can I download the chart?
Yes, as a high-resolution PNG for presentations and documents, or as SVG, a vector format that stays sharp at any size and can be edited in design tools.
Is it free and private?
Yes. There is no sign-up and no watermark, and your data never leaves your browser.
