Conditional formatting basics in Google Sheets - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is conditional formatting in Google Sheets?

Conditional formatting changes the look of cells automatically based on rules you set. For example, it can color cells red if the number is below 50.

beginner

How do you apply conditional formatting to a range of cells?

Select the cells, then go to Format > Conditional formatting. Set your rule and choose the formatting style, then click 'Done'.

beginner

What types of rules can you use in conditional formatting?

You can use rules like 'Cell is greater than', 'Text contains', 'Date is before', or custom formulas to decide when to format cells.

What happens if multiple conditional formatting rules apply to the same cell?

Google Sheets applies the first rule that matches. You can reorder rules to change which one applies first.

intermediate

Can you use formulas in conditional formatting? How?

Yes! Choose 'Custom formula is' in the rule type, then enter a formula that returns TRUE or FALSE. TRUE means the formatting applies.

Which menu do you use to start conditional formatting in Google Sheets?

A Format

B Data

C Insert

D Tools

Conditional formatting is found under the Format menu.

What does conditional formatting do?

A Adds comments to cells

B Deletes cells with errors

C Sorts data alphabetically

D Automatically changes cell appearance based on rules

Conditional formatting changes how cells look based on conditions you set.

If you want to highlight cells with values greater than 100, which rule type should you choose?

A Cell is greater than

B Text contains

C Date is before

D Custom formula is

Use 'Cell is greater than' to highlight numbers above a certain value.

What does a custom formula in conditional formatting need to return to apply formatting?

A A number

B A text string

C TRUE or FALSE

D An error

The formula must return TRUE to apply the formatting.

If two rules apply to the same cell, which one is used?

A The last rule in the list

B The first rule that matches

C Both rules apply at the same time

D No rule applies

Google Sheets applies the first matching rule based on the order.

Explain how to set up a conditional formatting rule to highlight cells with values less than 50.

Think about the steps from selecting cells to applying the rule.

Describe how custom formulas work in conditional formatting and give a simple example.

Remember the formula logic and how it controls formatting.

Practice

1. What does conditional formatting do in Google Sheets?

easy

A. Deletes cells that contain errors

B. Automatically sorts data alphabetically

C. Changes cell colors based on rules to highlight data

D. Creates charts from selected data

Solution

1. Step 1: Understand the purpose of conditional formatting

   Conditional formatting changes how cells look based on conditions you set.

2. Step 2: Identify the main effect of conditional formatting

   It highlights important data by changing cell colors or styles.

3. Final Answer:

   Changes cell colors based on rules to highlight data -> Option C

4. Quick Check:

   Conditional formatting = Highlight data [OK]

Hint: Think: 'Highlight cells that meet conditions' [OK]

Common Mistakes:

• Confusing conditional formatting with sorting
• Thinking it deletes or moves data
• Assuming it creates charts automatically

2. Which of these is the correct way to start creating a conditional formatting rule in Google Sheets?

easy

A. Right-click cells and choose Delete

B. Select cells, then go to Format > Conditional formatting

C. Click Insert > Chart

D. Select cells and press Ctrl+C

Solution

1. Step 1: Recall how to access conditional formatting

   In Google Sheets, conditional formatting is found under the Format menu.

2. Step 2: Identify the correct menu path

   Select cells, then choose Format > Conditional formatting to start a rule.

3. Final Answer:

   Select cells, then go to Format > Conditional formatting -> Option B

4. Quick Check:

   Format menu > Conditional formatting [OK]

Hint: Look under the Format menu for conditional formatting [OK]

Common Mistakes:

• Trying to create rules from Insert menu
• Using copy or delete commands instead
• Right-click menu does not have conditional formatting

3. You apply this conditional formatting rule to cells A1:A5: Format cells if 'Cell is greater than' 50 with red fill. If the values are 30, 55, 50, 70, 45, which cells will be red?

medium

A. A2 and A4 and A3

B. A1, A3, and A5

C. A2, A3, and A4 only

D. A2 and A4

Solution

1. Step 1: Identify which cells have values greater than 50

   Values: A1=30, A2=55, A3=50, A4=70, A5=45. Greater than 50 means strictly more than 50, so A2=55 and A4=70 qualify.

2. Step 2: Determine which cells get red fill

   Only cells with values greater than 50 get red fill, so A2 and A4 are red.

3. Final Answer:

   A2 and A4 -> Option D

4. Quick Check:

   Greater than 50 = A2, A4 [OK]

Hint: Check values strictly greater than 50, not equal [OK]

Common Mistakes:

• Including cells equal to 50
• Confusing 'greater than' with 'greater or equal'
• Selecting wrong cells by mistake

4. You want to highlight cells in B1:B5 that contain the word "Done" using conditional formatting with a custom formula. Which formula is correct?

medium

A. =B1="Done"

B. =IF(B1=Done, TRUE, FALSE)

C. =B1=Done

D. =B1 contains "Done"

Solution

1. Step 1: Understand how to write a custom formula for conditional formatting

   The formula must return TRUE for cells to be formatted. Comparing text requires quotes around the word.

2. Step 2: Check each option's correctness

   =B1="Done" uses =B1="Done" which returns TRUE if B1 equals "Done". =IF(B1=Done, TRUE, FALSE) lacks quotes around Done, causing error. =B1=Done lacks quotes around Done, causing error. =B1 contains "Done" is invalid syntax.

3. Final Answer:

   =B1="Done" -> Option A

4. Quick Check:

   Use =B1="Done" for exact text match [OK]

Hint: Use =Cell="Text" with quotes for text matching [OK]

Common Mistakes:

• Omitting quotes around text
• Using IF unnecessarily in conditional formatting
• Writing invalid syntax like 'contains'

5. You want to highlight all rows in A2:D10 where the value in column C is less than 100. Which conditional formatting custom formula should you use when applying to range A2:D10?

hard

A. =$C2<100

B. =C2<100

C. =$C$2<100

D. =C$2<100

Solution

1. Step 1: Understand how to apply conditional formatting to entire rows

   To highlight entire rows based on column C, fix the column with $ but allow row number to change.

2. Step 2: Analyze each formula for correct referencing

   =$C2<100 uses =$C2<100 which fixes column C but lets row number adjust per row. =C2<100 lacks $ fixing column, so column shifts incorrectly. =$C$2<100 fixes both column and row, so only row 2 is checked. =C$2<100 fixes row but not column, so column shifts incorrectly.

3. Final Answer:

   =$C2<100 -> Option A

4. Quick Check:

   Fix column with $ for row-based rules [OK]

Hint: Fix column with $ to apply rule per row [OK]

Common Mistakes:

• Fixing row number instead of column
• Not fixing column causing wrong columns checked
• Using absolute references that don't adjust per row
