Chart Builder
Create bar, line, pie, and more charts from your own data. No signup — export as PNG or PDF.
Chart Builder turns a simple table of numbers into a polished, presentation-ready chart in seconds — choose from eight chart types, drop in your own data, restyle the colours, and export the result as a PNG image, a print-ready PDF, or a CSV, all without creating an account.
Instead of wrestling with a spreadsheet's clunky chart menus, you get a focused canvas built on Chart.js. Pick bar, horizontal bar, line, area, pie, doughnut, radar, or scatter; type values straight into the editable data grid or import a CSV exported from Excel or Google Sheets; then add a title, switch between six curated colour palettes, and toggle the legend, grid lines, and value labels until it reads exactly the way you want. Up to six datasets can sit side by side, so comparing revenue against expenses or this year against last is one click away. People use it to:
- Build quick bar and line charts for reports, slide decks, and dashboards
- Visualise spreadsheet data without opening heavyweight desktop software
- Turn survey or KPI numbers into pie, doughnut, or radar graphics
- Export clean PNG or PDF images to drop into documents and presentations
Everything runs locally in your browser — the figures you enter, the CSV you import, and the chart you render never leave your device and are never uploaded to a server. That makes it safe for sensitive financial or business data, and it means the tool keeps working even when you are offline. Close the tab and nothing is stored; export a CSV first if you want to keep your data for next time.
- Pick a chart type from the type grid — bar, horizontal bar, line, area, pie, doughnut, radar, or scatter.
- Edit the data table directly, or click Import CSV to load a sheet exported from Excel or Google Sheets.
- Add rows or extra datasets (up to six) with the buttons below the table to expand your data.
- Set a title, choose one of the six colour palettes, and toggle the legend, grid lines, and value labels.
- Click Download PNG or PDF to export the chart, or CSV to save your data for next time.
Bar, horizontal bar, line, area, pie, doughnut, radar and scatter. Each type re-renders instantly when you switch.
Yes — paste data directly into the editable table, or use the Import CSV button to load a sheet exported from any spreadsheet tool.
Chart.js draws to an HTML5 canvas in your browser — no data ever leaves the page. Export options use the same canvas.
It depends on what your data shows. Use bar or horizontal bar to compare categories, line or area to show a trend over time, pie or doughnut to show parts of a whole, radar to compare several metrics across items, and scatter to reveal the relationship between two numeric values. You can switch types at any time and the chart re-renders instantly, so it is easy to try a few and see which reads best.
Use the buttons under the preview. Download PNG saves a high-resolution image you can drop into documents or slides, PDF opens a print-ready page you can save or send to a printer, and CSV downloads your underlying data so you can reload it later. The PNG keeps the same background and colours you see on screen.
Yes. Click Import CSV and pick a file exported from Excel, Google Sheets, Numbers, or any other tool. The first row is treated as your column headers (the first column being the labels and each later column a dataset), and the rows below become your data. You can import up to one label column plus six datasets; anything beyond that is trimmed automatically.
Yes. Choose from six built-in palettes — Default, Vibrant, Pastel, Ocean, Sunset, and Mono — and the whole chart recolours instantly. You can also set a custom title and toggle the legend, grid lines, and on-bar value labels. The chart automatically adapts its background and text colours to match light or dark mode.
