CSV to Chart
Turn a CSV file into a presentable chart — bar, line, area, or donut — in seconds, then download it as SVG or PNG for slides and documents. Your data is parsed in the browser and never uploaded.
🔒 100% private — this tool runs in your browser; files are never uploaded.
How it works
- Add your CSV. Drop a .csv file or paste CSV text. The first row is treated as headers; your data stays in the browser.
- Pick columns and a chart type. Choose the label column and one or more numeric columns, then switch between bar, line, area, and donut to see what reads best.
- Download. Export the chart as a crisp SVG (scales to any size) or a PNG for quick pasting into slides and docs.
Honest limitations
- Charts are capped at 8 series / 8 donut slices for readability — extra donut slices fold into "Other".
- Semicolon- or tab-delimited files should be exported as comma-separated CSV first.
Frequently asked questions
Is my data uploaded?
No. The CSV is parsed and charted entirely in your browser — nothing is sent to a server, so it is safe for internal or confidential numbers.
What CSV format is expected?
A header row followed by data rows, comma-separated, with standard double-quote escaping. The first text-like column is suggested as labels and numeric columns as series, but you can change both.
Why does the donut fold small slices into "Other"?
Beyond eight slices a donut stops being readable, so smaller slices are grouped into an "Other" slice. Switch to a bar chart when you need every category visible.
SVG or PNG — which should I download?
SVG stays sharp at any size and is ideal for slides and print. PNG is a fixed-size image that pastes anywhere.
