Charttoolbox

Charttoolbox

Turn CSV and Excel data into clear charts in your browser

Charttoolbox turns spreadsheet data into charts without setting up a full BI dashboard. Upload a CSV, TSV, XLS, or XLSX file, paste a table, or start with sample data. Choose from heatmaps, pie/donut charts, bar charts, line charts, scatter plots, histograms, and correlation matrices. Adjust the fields and presentation, then export a PNG or SVG. Your spreadsheet contents are processed locally in your browser. The tools are free to use and require no account.
