It works on bar charts, line charts, pie charts, scatter plots, and even scanned tables, so you can recover data from a screenshot or PDF figure without retyping it. It is built for analysts, researchers, and students who need to reuse data trapped inside images.

Tips for Best Results

  • Upload a high-resolution, uncropped image so axis labels and values are legible.
  • Charts with clear gridlines and labeled axes produce the most accurate numbers.
  • Spot-check a few extracted values against any labels visible on the chart.
  • For dense scatter plots, expect approximate values and verify against the source if precision is critical.

What does Chart to CSV do?

It analyzes an uploaded chart or graph image and extracts the approximate underlying data values, returning them as a CSV file you can open in any spreadsheet.
