Sparktable

SparkTable combines a mini spreadsheet with row sparklines and summary statistics. Enter row and column labels, fill in numeric cells, and see each row trend as a tiny line chart beside the data. View row and column stats including sum, mean, min, and max.

Export a text summary to the clipboard for notes or email. Save multiple tables, edit cells anytime, and review everything on one screen. SparkTable works fully offline with local JSON storage—no login, ads, or cloud sync.

Great for weekly sales grids, lab readings, or any small table where you want numbers plus quick visual trends.
