Cross-column conditional rules in Google Sheets - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a cross-column conditional rule in Google Sheets?

A cross-column conditional rule checks values across two or more columns to apply formatting or logic based on conditions involving multiple columns.

beginner

How do you write a formula for conditional formatting that compares values in column A and column B?

Use a formula like =A1>B1 in the conditional formatting rule to compare values in the same row across columns A and B.

Why do you use absolute and relative references carefully in cross-column conditional rules?

Because relative references adjust for each cell, while absolute references stay fixed. For cross-column rules, you usually want relative row references to compare cells in the same row across columns.

beginner

Example: What does the formula =AND(A1>10, B1<5) do in conditional formatting?

It applies formatting only if the value in column A is greater than 10 AND the value in column B is less than 5 for the same row.

beginner

Can cross-column conditional rules be used to highlight rows where two columns have the same value?

Yes! Use a formula like =A1=B1 in conditional formatting to highlight rows where the values in columns A and B match.

Which formula highlights cells in column A when the value in column A is greater than the value in column B in the same row?

A =A1>B1

B =B1>A1

C =A$1>B$1

D =$A1>$B1

The formula =A1>B1 compares values in the same row across columns A and B. Relative references allow the formula to adjust for each row.

What does the formula =AND(A1>5, B1<10) do in conditional formatting?

A Formats if A1 is greater than 5 OR B1 is less than 10

B Formats if A1 is greater than 5 AND B1 is less than 10

C Formats if A1 equals B1

D Formats if either A1 or B1 is empty

AND requires both conditions to be true: A1 > 5 and B1 < 10 for formatting to apply.

In cross-column conditional formatting, why avoid using absolute row references like $1 in formulas?

A Because it makes the formula slower

B Because it highlights the wrong columns

C Because it causes errors in Google Sheets

D Because it fixes the row and stops the formula from adjusting for each row

Absolute row references fix the row number, so the formula won't adjust for each row, which is usually needed in cross-row comparisons.

Which formula highlights rows where values in columns A and B are equal?

A =A1=B1

B =AND(A1,B1)

C =A1<>B1

D =OR(A1,B1)

The formula =A1=B1 returns TRUE when values in columns A and B are the same in the same row.

What is the main benefit of using cross-column conditional rules?

A To create charts

B To sort data automatically

C To format cells based on values in other columns

D To delete rows

Cross-column conditional rules let you highlight or format cells based on conditions involving multiple columns.

Explain how to create a conditional formatting rule that highlights cells in column A when the value is greater than the value in column B in the same row.

Think about comparing cells in the same row across two columns.

Describe why relative references are important in cross-column conditional formatting formulas.

Consider what happens when the formula is applied to multiple rows.

Practice

1. In Google Sheets, you want to check if the value in column A is greater than the value in column B for the same row. Which formula correctly returns TRUE or FALSE for this condition in row 2?

easy

A. =A2>B2

B. =IF(A2, B2)

C. =A2+B2

D. =IF(A2<B2, TRUE, FALSE)

Solution

1. Step 1: Understand the comparison needed

   The question asks to check if the value in column A is greater than column B in the same row, which is a simple comparison.

2. Step 2: Identify the correct formula syntax

   The formula =A2>B2 directly compares the two cells and returns TRUE or FALSE accordingly.

3. Final Answer:

   =A2>B2 -> Option A

4. Quick Check:

   Simple comparison formula =A2>B2 [OK]

Hint: Use direct comparison like =A2>B2 for cross-column checks [OK]

Common Mistakes:

• Using IF without condition like IF(A2, B2)
• Adding values instead of comparing
• Using wrong comparison operators

2. Which of the following formulas correctly applies a conditional rule to return "Yes" if the value in column C is equal to the value in column D, otherwise "No", for row 3?

easy

A. =IF(C3=D3, "Yes", "No")

B. =IF(C3==D3, "Yes", "No")

C. =IF(C3=D3, Yes, No)

D. =IF(C3<>D3, "Yes", "No")

Solution

1. Step 1: Understand the equality check syntax in Google Sheets

   Google Sheets uses a single equals sign = for comparison inside IF, not double equals.

2. Step 2: Check the correct use of text strings in IF

   Text values must be in quotes, so "Yes" and "No" are correct.

3. Final Answer:

   =IF(C3=D3, "Yes", "No") -> Option A

4. Quick Check:

   Use single = and quotes for text in IF [OK]

Hint: Use single = for comparison and quote text in IF [OK]

Common Mistakes:

• Using double == which causes error
• Not quoting text strings
• Using <> instead of = for equality

3. Given the formula =IF(AND(A2>10, B2<5), "Pass", "Fail") in cell C2, what will be the result if A2=12 and B2=3?

medium

A. TRUE

B. "Fail"

C. "Pass"

D. FALSE

Solution

1. Step 1: Evaluate the AND condition with given values

   A2>10 is TRUE because 12>10, and B2<5 is TRUE because 3<5. AND(TRUE, TRUE) returns TRUE.

2. Step 2: Apply IF based on AND result

   Since AND is TRUE, IF returns "Pass" as specified.

3. Final Answer:

   "Pass" -> Option C

4. Quick Check:

   AND(TRUE, TRUE) = TRUE, so IF returns "Pass" [OK]

Hint: Check each condition inside AND before IF [OK]

Common Mistakes:

• Confusing AND logic with OR
• Ignoring comparison operators
• Expecting TRUE/FALSE instead of text output

4. You wrote this formula in cell D2: =IF(A2>B2, "Higher", "Lower"). But it always shows "Lower" even when A2 is greater than B2. What is the likely problem?

medium

A. The formula uses wrong comparison operator

B. The IF function syntax is incorrect

C. The formula needs to be entered as an array formula

D. Cells A2 or B2 contain text, not numbers

Solution

1. Step 1: Understand why comparison might fail

   If A2 or B2 contain text (like numbers stored as text), the comparison A2>B2 may not work as expected.

2. Step 2: Check formula syntax and usage

   The formula syntax is correct and does not require array formula. The issue is likely data type mismatch.

3. Final Answer:

   Cells A2 or B2 contain text, not numbers -> Option D

4. Quick Check:

   Text in number cells breaks numeric comparisons [OK]

Hint: Check cell data types if comparisons fail [OK]

Common Mistakes:

• Assuming syntax error without checking data
• Trying array formula unnecessarily
• Using wrong operators like ==

5. You want to create a formula in column E that labels each row as "OK" if the value in column A is greater than column B and the value in column C is not empty. Otherwise, it should show "Check". Which formula correctly does this for row 2?

hard

A. =IF(A2>B2, IF(C2="", "OK", "Check"), "Check")

B. =IF(AND(A2>B2, C2<>""), "OK", "Check")

C. =IF(AND(A2>B2, NOT(ISBLANK(C2))), "OK", "Check")

D. =IF(OR(A2>B2, C2<>""), "OK", "Check")

Solution

1. Step 1: Understand the conditions to combine

   The label "OK" requires both: A2>B2 and C2 not empty. This means both conditions must be true, so AND is needed.

2. Step 2: Check formula options for correct logic

   =IF(AND(A2>B2, C2<>""), "OK", "Check") uses AND with A2>B2 and C2<>"" which means C2 is not empty. This matches the requirement exactly.

3. Final Answer:

   =IF(AND(A2>B2, C2<>""), "OK", "Check") -> Option B

4. Quick Check:

   Use AND for all conditions, check non-empty with <>"" [OK]

Hint: Use AND and <>"" to check multiple conditions and non-empty cells [OK]

Common Mistakes:

• Using OR instead of AND
• Using ISBLANK incorrectly
• Nesting IF unnecessarily
