Data Extractor

Zenith Data Extractor

turns images of charts back into usable numbers. Load any plot, a scanned pump curve, a datasheet figure, a published graph — trace each line with smooth spline handles, set your axes (linear or log), and extract clean, point-by-point data in seconds. You get a styled Excel workbook, a high-resolution regenerated chart, and an annotated overlay you can trust. Built for engineers and analysts who need the data, not just the picture.
