Sankey Studio - Turn flow data into clear Sankey diagrams

by•
Sankey Studio turns plain text or small CSV, TSV, Markdown, or JSON files into clear Sankey diagrams. Start from income statements, household budgets, energy flows, or your own data; adjust spacing, colours, sorting, and zoom; then export SVG or PNG. It runs without an account and includes a local parsing fallback when AI normalization is unavailable. Built for analysts, students, operators, and anyone who needs to explain how quantities move.

Hi Product Hunt 👋 I built Sankey Studio because I wanted a quick way to turn messy flow notes and spreadsheet exports into a diagram without wrestling with a charting library. It supports simple Source -> Target: value lines, small files, and ready-to-edit examples for income statements, household budgets, and energy flows. I’d love feedback on which flows you’d most want to visualise next, API generation, financial statements, or something else. Try it directly and tell me where the workflow feels unclear.
