GetData vs DataFromChart: Extract Chart Data

GetData Graph Digitizer and DataFromChart both recover numerical values from a chart image, but they are built for different environments. GetData Graph Digitizer 2.26 is a downloadable Windows application. DataFromChart runs in a browser and supports a mix of manual, colour-based, and AI-assisted extraction.

The comparison below uses the capabilities listed on the official GetData website and DataFromChart’s current product documentation. Those published feature lists do not establish that one tool is more accurate than the other.

Automatic extraction	Line tracing and area digitizing	Colour extraction and opt-in AI extraction
Manual point placement	Yes	Yes
Workspace/project save	Yes	Yes
Documented exports	TXT, XLS, XML, DXF, EPS	CSV, TSV, XLSX, JSON

GetData Graph Digitizer’s documented workflow

The official GetData product page describes four steps: open a graph, set the coordinate system, digitize automatically or manually, then copy or export the recovered values.

Its automatic tools cover two cases:

Auto trace lines follows a solid line from a selected starting point.
Digitize area samples a user-selected area and is documented for solid or dashed lines.

Manual point capture and an eraser are available when automatic tracing is not suitable. Workspaces can be saved and reopened.

GetData’s documented export formats are TXT, legacy Excel XLS, XML, DXF, and EPS. The official pages do not list CSV, modern XLSX, or JSON as export formats.

DataFromChart’s workflow

DataFromChart accepts an image or PDF in the browser. You can calibrate the visible axes, then place points manually, isolate a series by colour, or opt into AI-assisted axis and point detection. Automatically extracted points remain editable before export.

Manual extraction and CSV, TSV, XLSX, and JSON export are available without buying AI credits. A registered account is required to upload a chart; each account includes three AI runs before additional AI extraction uses paid credits.

Which tool fits which job?

Choose GetData Graph Digitizer when:

you need a Windows desktop workflow that can run offline;
your downstream process requires XLS, XML, DXF, or EPS;
your source is one of its documented raster formats; or
its line-trace and area-digitizing workflow matches the chart.

Choose DataFromChart when:

you need to work from macOS, Linux, ChromeOS, or another browser-capable system;
the source is a PDF, PNG, or SVG;
you need CSV, TSV, modern XLSX, or JSON output; or
you want manual, colour-based, and AI-assisted methods in one workflow.

Version and compatibility caveat

GetData’s official download page identifies version 2.26, dated June 19, 2013, and lists support through Windows 10. That does not prove that the application fails on newer Windows versions, but the vendor page does not document them. Check the current installer in your own environment before making it part of a production workflow.

Neither vendor’s feature list establishes comparative extraction accuracy. Image resolution, axis calibration, line thickness, compression, and point placement can all affect the recovered values. Test either tool on a chart with known source data if precision matters.

Compare the workflow on a chart you already know. Open the DataFromChart extractor, recover the same series in both tools, and compare the exported values against the source data.
