The app for creation and analyzing pivot tables from arbitrary one.
You can upload or create a base table, add/edit/delete rows, and that uploaded table is only base to quickly create a lot of pivot tables.
Pivot table is created from values of two columns of a base table, so, for example, from a base table with 10 columns it's possible to create 90 different pivot tables.
Rows and columns of pivot tables can be reordered, excluded/included, combined, set aliases and for date typed values can be grouped by years/months/days.
Also you can see bar or line charts of selected pivot row/column.
There are another additional features.

To make learning the program easier, there is a built-in test table, which you can change or even delete, and then restore the test table from the menu with one click
