What you'll learn

Key ideas in Excel for Accounting

  • Keeping inflows and outflows in separate columns eliminates confusing plus/minus signs
  • Dedicated Debit and Credit columns allow clean Excel formulas to sum each direction independently
  • Mixing positive and negative numbers in one column makes typo detection and formula building much harder
  • Accounting format aligns all decimal points vertically for clean column reading
  • Typing raw numbers without formatting often leaves decimals jagged across the column
  • Storing numbers as text prevents Excel from treating them as math-ready values
  • A running balance formula takes the prior row's balance and applies the current row's activity
  • Debits (money received) are added to the previous balance
  • Credits (money spent) are subtracted from the previous balance
  • The small square at the bottom-right of a selected cell is the AutoFill handle
  • Dragging the AutoFill handle detects patterns like dates or incrementing codes without manual retyping
  • Freeze Panes (specifically Freeze Top Row) locks header labels at the top of the screen
  • Headers stay visible during vertical scrolling so columns remain identifiable deep in a sheet
  • Merging cells prevents selecting and sorting single columns cleanly in Excel
  • Center Across Selection visually centers text over multiple cells while keeping each cell independent
  • Accounting format standardizes negative numbers by wrapping them in parentheses or showing them in red
