How to Use AOP3D Sheets

Type & move: click a cell and type, or use the formula bar. Arrows, Tab and Enter move; Esc cancels; double-click edits in place.

Formulas: begin with =, e.g. =SUM(A1:A10), =AVERAGE(B2:B9), =IF(A1>10,"big","small"), =ROUND(C1*1.2,2). Errors show as #DIV/0! or #ERROR.

Format & files: drag or Shift-click for a range, then Bold, Italic, alignment, $ / % / decimal formats and color pickers. Import CSV brings a sheet in; Export CSV downloads values (formulas become results); Print makes a clean paper copy.
