A pivot table summarises rows by grouping them into categories. Choose row and column dimensions, then aggregate a metric such as sales or quantity.

You can use sum for numeric columns or count to tally occurrences. More aggregation types are coming soon.

The tool comfortably handles tens of thousands of rows in modern browsers. For very large datasets, consider running the pivot server-side.
