Cell Formatting: Colours, Hidden Rows and Columns, Toolbar Control

In this lesson you will learn how to highlight answer cells in a spreadsheet so readers can find them easily, hide rows or columns with working calculations, clear formatting without deleting numbers, and use ribbon or full-screen view control for more sheet space.

    1 - Introduction ~5 mins

    Welcome

    A spreadsheet can hold a lot of working maths that the reader never needs to see. Today you learn three presentation habits that make a sheet feel finished: highlight the answer cells, hide intermediate calculation rows or columns, and clear messy formatting without wiping the numbers. These habits matter when you hand a budget, a VAT sheet, or a Work Experience tracker to a supervisor, a teacher, or a VET examiner.

    By the end of this lesson, you will be able to:

    • Highlight answer cells so a reader knows where to look
    • Hide and unhide rows or columns used for intermediate calculations
    • Clear formatting without deleting the underlying data
    • Use ribbon or full-screen view control when you need more sheet space

    Warm-up

    Think of one spreadsheet already in your {{code:Project_Portfolio}} (VAT calc, time tracker, or multi-sheet workbook). If a stranger opened it tomorrow, would they know which cells hold the final answers, and which cells are just working maths?

    2 - Key Concepts ~6 mins

    Three presentation habits turn a working spreadsheet into something a supervisor can scan in ten seconds. A fourth habit frees screen space while you check a long range.

    ConceptWhy it mattersExample
    Answer-cell highlight — a fill colour on the cells that hold the final results a reader came for Supervisors and examiners skim; colour tells them where to look without reading every formula Pale green on the Gross (€) column of a side-hustle VAT sheet so the take-home total stands out
    Hidden rows or columns — intermediate calculations kept in the sheet but not shown on screen or in print Keeps the working maths available for you, while the reader only sees clean inputs and answers Hide the VAT amount column after the Gross formula is working; unhide it later if you need to debug. The same right-click Hide works on a row header for a scratch calc row.
    Clear formatting — strip fill, bold, borders, and number formats while leaving the values and formulas untouched Lets you reset a messy trial layout without retyping data or rebuilding formulas Clear neon trial colours from a draft Work Experience hours sheet before applying one calm highlight scheme
    Toolbar and ribbon control — collapsing or expanding the top menu strip (or using full screen) so you can see more of the sheet Gives you screen space when checking a long range, then brings the tools back when you need them Collapse the ribbon (or use full screen) while checking a long Work Experience hours list, then expand it again to use Fill Color
    Worked example

    Worked example you will polish next: a starter three-row product sheet for a student selling stickers, phone cases, and lanyards. Column D already holds VAT amounts (intermediate — you will hide it). Column E already holds Gross totals (answers — you will highlight them). You will also hide a scratch trial row and clear messy trial colours without deleting the numbers.

    3 - Step-by-step Task ~18 mins

    Open the starter pricing sheet (products, VAT, Gross, and TOTAL formulas already built). Highlight the answer cells, hide the intermediate VAT column, hide a scratch trial row, then clear messy trial formatting without losing any numbers. Your teacher will demo the first highlight, hide, and Clear Formats on the classroom screen; then follow the steps for your platform.

    Note

    Note on numbers: some Gross values look like 15.375 or 24.231. That is fine for this lesson — we are not currency-formatting yet.

    4 - Common Issues ~3 mins

    Common Issues

    IssueSolution
    I hid a column and now a formula shows {{code:#REF!}} Hide is not the problem — something was deleted. Use Undo ({{kbd:Ctrl+Z}} / {{kbd:Cmd+Z}}). Hide only removes the column from view; delete removes it from the sheet and breaks references.
    I cannot find the hidden column or row to unhide it Select the columns or rows on both sides of the gap (for example C and E if D is hidden, or rows 6 and 8 if row 7 is hidden), then right-click and choose Unhide. In Google Sheets you can also click the small arrows in the header gap.
    Clear Formats wiped my numbers You likely chose Clear All or Delete instead of Clear Formats. Undo immediately. Clear Formats only removes styling; values and formulas stay.
    My whole sheet is one bright colour and looks worse Select only the answer range before using Fill Color. One calm highlight on the result cells is enough. Use Clear Formats on the noisy areas and start again with a smaller selection.

    5 - Independent Practice ~18 mins

    Independent Practice

    Your goal: Open one Something Real spreadsheet from your portfolio and make it readable at a glance — answer cells highlighted, intermediate working rows or columns hidden, and any messy trial formatting cleared — so a supervisor or examiner knows where to look.
    Time: ~20 minutes
    Task: Open your {{code:Project_Portfolio}} folder, go to {{code:09_specialism/sm3/}}, and open one existing project spreadsheet (for example {{code:sm3_vat_calc}}, your time tracker, or your multi-sheet workbook). Before you start, watch your teacher's short think-aloud on a sample sheet: which cells are answers (green), which column is working maths (hide), and which neon styling should be cleared. Then apply the same three habits on your own file: highlight the answer cells a reader needs, hide at least one intermediate calculation row or column, and clear any messy trial formatting without deleting data. If your project sheet has no working column yet, open {{code:sm3_vat_calc}} (or duplicate {{code:sm3_format_practice}}) and apply the three habits there. Leave the file saved in {{code:sm3}} under its existing name.
    Success criteria:
    • A reader can spot the final answers in under five seconds because those cells use a calm highlight colour
    • At least one intermediate calculation row or column is hidden, and changing an input still updates the answers
    • No random trial colours or leftover styling remain on working areas; only deliberate formatting is left
    • The updated spreadsheet is saved in {{code:09_specialism/sm3/}} under its existing name with all data and formulas intact
    • This updated sheet stays in {{code:09_specialism/sm3/}} as evidence for your spreadsheet Key Assignment / Practical Achievement log — do not rename it
