Disclaimer: Charts, summary statistics and the written insights are computed from the data you load and are only as accurate and complete as that data. Verify anything you act on against the underlying figures.

Open a table from CSV, TSV, JSON, Excel (.xlsx/.xlsm) or OpenDocument (.ods), paste data, or start from a built-in practice dataset. Clean it with a recipe of named steps you can re-run in order: read dates, rename or drop columns, keep a subset, fill missing values (mean, median, mode, a constant, previous/next, zero or interpolation), drop rows with gaps, and remove duplicate rows. Then explore it four ways at once: a column profile with distributions and top values, an aggregation/pivot with grouped measures, SQL queries you can save for reuse, and charts with sensible type suggestions. Plain-language insights name the columns and figures they used, and you can export the results as CSV or JSON and build an HTML report. Analyses you save are kept on your device.
