Pivot4U is an add-in for Microsoft Excel. Once installed, it allows you to enter or edit data in pivot tables directly. Just go to the Add-Ins tab of Excel, select Pivot4U On, set the cursor on any cell in the table and change its value. You can change data in the cells, subtotals row or Grand Totals column. Once the value is changed, all totals are recalculated automatically. Editing cells in pivot tables is fairly easy right out of the box.
