About

Make bar, line, pie, scatter, histogram, heatmap and correlation charts from CSV or Excel. Files stay in your browser. Free, no account, export SVG or PNG. Plenty of online chart makers ask you to upload your spreadsheet first. Charttoolbox reads, calculates and renders inside the browser and states that file names, contents and values are not sent to its servers. Seven generators: bar, line, pie/donut, scatter, histogram, heatmap and Pearson correlation. Open CSV, TSV, XLS or XLSX, or paste from Excel or Sheets. Download editable SVG or PNG. Free for personal, academic and commercial use. Preview limits: no cloud save, import cap about 2,000 rows, bar charts do not stack.
