KherveSheet is a desktop spreadsheet application for scientists, built in Python and running on Windows.

Plotting Charts are generated using matplotlib and embedded directly in the sheet as movable, resizable objects. You have full control over axes, scales, ticks, titles and grids. Curve fitting and peak fitting are supported, with goodness-of-fit reporting overlaid on the plot.

Every cell can also run a full Python program, not just a formula. An integrated AI assistant can generate the cell code from a plain-language description if needed.

Learn by doing with 300 ready-made scientific examples covering plotting, data analysis, fitting and simulation.

Built entirely in Python, KherveSheet adds a familiar Excel-style grid, an optimisation solver, and a native .ksheet format with CSV and Excel import/export. Runs on Windows.
