1.4 Formatting that helps rather than decorates

Your sheet is readable by someone who did not build it.

Formatting in Excel is about making a sheet readable by someone who did not build it: number formats, alignment, borders used with restraint, and freeze panes so headings stay visible. It follows the entry and formula topics because format is a coat of paint on values that already behave. The important confusion to settle is that formatting changes how a value looks, never what it is — a cell showing two decimal places may hold many more. Merged cells look tidy and break sorting and selection, which is why the topic teaches the alternative.

Work through these

  • Number formats: currency, percentage, date, and the Indian digit grouping

    A number format changes how a value is displayed without changing the value itself, which is why a rounded-looking figure can still add up oddly. Indian digit grouping is available and is worth setting deliberately.

  • Alignment, wrapping, merging (and why to avoid merging)

    Alignment and wrapping make a sheet readable; merging cells makes it look tidy and breaks sorting, filtering and formulas. This item is where you learn to reach for centring across a selection instead.

  • Borders, fills and restraint

    Borders and fills are useful in small quantities and become noise in large ones. The advice here is restraint, because a heavily decorated sheet is harder to read, not easier.

  • Freeze panes and printing on one page

    Freezing the header row keeps it visible while scrolling, and the print settings decide whether the sheet arrives on one page or seventeen. Both are quick and both are usually forgotten.
