About Charts & Data Tools
Charts and Data Tools has 25 tools split between charts and CSV work. Paste numbers or a CSV into the Bar Chart Maker, line, pie, donut, scatter or area chart makers and download a sharp SVG or a PNG. Project and planning charts include the Gantt Chart Maker, an org chart builder and a timeline maker, each with its own simple line format.
For spreadsheets, the CSV Viewer opens a file as a sortable, searchable table, and other tools clean, deduplicate, split, merge, transpose or extract columns. The Pivot Table Builder summarises a CSV by row and column fields with sum, count, average, minimum or maximum. Several of these also read .xlsx files. Charts include a written description of the data for screen readers, and files are read on your device rather than uploaded.
