Spreadsheet to Chart

Turn CSV, TSV, or XLSX data into a reviewed bar, line, pie, or scatter chart in your browser. Choose the fields and aggregation explicitly, inspect excluded rows, and export the chart and its tidy data.

Saved sessions

Add a CSV, TSV, or XLSX file

The file stays in this browser. Legacy .xls, macros, and formula recalculation are not supported.

Files, prompts, and results stay in this browser. Browser storage can still be cleared by you, private mode, or browser cleanup.
Private spreadsheet visualization

Parsing, aggregation, chart rendering, exports, saved sessions, and optional local AI explanation stay in your browser. Spreadsheet values never enter BaseToolbox analytics.

Current limitations
  • The tool supports CSV, TSV, and modern XLSX, but not legacy .xls, macros, pivot tables, or desktop-Excel formula recalculation.
  • A category chart requires an explicit aggregation; it will not silently select one value from duplicate categories.
  • Invalid numeric rows are excluded and counted. Review the tidy result before relying on the visualization.
  • Browser storage and cached local AI models can be removed by clearing site data, private browsing, or browser storage eviction.
