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.
Frequently Asked Questions
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.
What chart types and file formats does it support?
It handles bar charts, line charts, pie charts, scatter plots, and scanned tables. Upload the chart as a standard image such as JPG, PNG, or WebP.
What output do I get?
You get CSV data with the chart's categories and values that you can copy or download and open directly in Excel, Google Sheets, or any analytics tool.
How accurate are the extracted numbers?
Values are estimated by reading the chart visually, so they are approximate, especially when axis labels are unclear or data points overlap. Verify against the source when precision matters.
Can it read tables, not just charts?
Yes. It can pull rows and columns from scanned or screenshotted tables into CSV in addition to plotted charts.
Can I use the extracted data commercially?
Yes, you can use the recovered data in your own analysis and reports. Free covers 5 extractions per day with no signup; Pro is $19/month.
What happens to the chart images I upload?
