Right-click for rows, groups, phases and columns. Drag a row by its number, or a column by its heading; a phase or group brings everything under it. Double-click a heading to rename it. Copy and paste with Excel works both ways. A row whose LID is a whole number (1, 2, 3) is a phase; a row with only a name in Activity (no LID, platform or spend) is a group inside it. Both add up the lines under them. Type the Budget, and each line's Weighting, eCPC and CTR % (in blue); Spend, Clicks, Impressions and the subtotals are worked out (shaded). Changes save as you go.
