Use the free Chart Maker from CSV below: your data never leaves your browser — all work happens on your device, and nothing is uploaded to any server.
A table of numbers is hard to read, but a chart of the same numbers is understood in seconds. The Chart Maker from CSV turns pasted data into a bar chart, a line chart, or a pie chart without a spreadsheet, an account, or an upload. Paste two columns, one for labels and one for numbers, and the tool draws the chart on the page. You can then download it as a PNG image for a report, a slide, or a post.
The tool is deliberately simple. It does not try to replace a full spreadsheet. It answers one question fast: what does this data look like? A shop owner can paste monthly sales and see the best month at a glance. A student can paste survey results and see which answer won. A blogger can paste figures from a public dataset and make a chart for an article, all in under a minute.
To use it, paste your CSV with a header row first. The sample shows the shape: month,sales on the first line, then one row per point. Set the label column and the value column, counting from zero, so the first column is 0 and the second is 1. Pick a chart type, then press Draw chart. Bar charts are best for comparing separate categories, such as sales by month or votes by candidate. Line charts are best for showing a trend over time, such as temperature across a week. Pie charts are best for showing shares of a whole, such as how a budget is split, and they work best with five or fewer slices.
Your chart appears on a canvas below the buttons. If the chart library fails to load, the tool still draws a simple bar chart directly on the canvas, so you are never left with a blank page. Press Download PNG to save the image. The PNG has a plain background and works in documents, slides, and image editors.
Data preparation matters more than chart settings. Keep one header row, keep labels short, and keep the value column purely numeric. A stray currency symbol or a thousands comma inside a number can turn that row into zero, because the tool reads the value as a plain number. If a bar looks wrong, check that row first. Rows with missing values are drawn as zero, which is honest but worth knowing before you present the chart.
The tool reads only the two columns you select, so a wider CSV is fine. Extra columns are ignored, not deleted, and nothing about your paste is stored. Because everything runs in your browser, you can chart private figures, such as household spending or small business sales, without sending them to any server.
Charts also reveal mistakes that tables hide. A value ten times larger than its neighbours jumps out as a bar that towers over the rest, and a missing month shows up as a gap in a line. Many users paste data just to check it, then fix the source file and paste again. That quick visual check is one of the most useful things a simple chart tool can do.
How to make a chart from CSV

Frequently asked questions
Do I need a spreadsheet app? No. Paste CSV text directly, even copied from a spreadsheet, and the tool draws the chart.
Which chart type should I pick? Bars for comparing categories, lines for trends over time, pie for shares of a whole with few slices.
Why is one bar zero? That row’s value was probably not a plain number. Remove currency symbols and thousands separators and try again.
Is my data uploaded? No. Everything runs in your browser, and nothing is sent or stored.
Use the chart as a starting point, not as proof. Check the numbers behind any chart you publish, keep the source data with the image, and remember that a chart can only be as honest as the table it came from.
