About Plot2Data
What Is Plot2Data?
Plot2Data is a free, browser-based tool that converts chart images into structured numerical data. Whether you have a screenshot of a line chart, a bar graph from a PDF report, or a scatter plot from a research paper, Plot2Data uses advanced AI to automatically extract the underlying data points and deliver them as clean, ready-to-use CSV data.
Our tool supports over 16 different chart types including line charts, bar charts, scatter plots, pie charts, area charts, box plots, histograms, heatmaps, candlestick charts, and more. Simply upload an image, and our AI does the rest.
Why We Built Plot2Data
Researchers, data analysts, and students frequently encounter valuable data locked inside chart images. Academic papers often present findings as figures without providing the raw data. Legacy reports contain charts that were never digitized. Screenshots from dashboards and presentations hold data that needs further analysis.
Manually reading values from chart images is tedious, error-prone, and time-consuming. Traditional plot digitizer tools require painstaking point-by-point clicking. We built Plot2Data to eliminate this friction by leveraging modern AI to automate the entire extraction process in seconds.
Our Technology
Plot2Data is powered by Google Gemini Vision AI, one of the most advanced multimodal AI models available. The AI uses computer vision to identify chart elements such as axes, labels, gridlines, data points, and legends. It then maps visual positions to numerical values with high precision, extracting structured data that you can immediately use in Excel, Google Sheets, Python, R, MATLAB, or any other data analysis tool.
Who It's For
- Researchers digitizing figures from published scientific papers and journal articles
- Data Analysts recovering data from legacy reports, dashboards, and presentations
- Students extracting chart data for assignments, theses, and research projects
- Engineers analyzing stress-strain curves, performance charts, and technical plots
- Financial Analysts reading stock charts, market trends, and economic indicators
- Journalists fact-checking data visualizations and extracting source data
Our Mission
We believe that data trapped inside visual formats should be universally accessible. Plot2Data is free to use and built with privacy in mind: uploaded images are processed temporarily and never stored on our servers. Our goal is to save you time and effort so you can focus on what matters most — analyzing and understanding your data.
