Column transformations in Excel - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a column transformation in Excel?

A column transformation means changing or creating new data in a column by using formulas or functions to modify the original values.

beginner

How do you apply a formula to transform an entire column in Excel?

You write the formula in the first cell of the new column, then drag the fill handle down to copy the formula to other cells in that column.

beginner

What does the formula =UPPER(A2) do when applied to a column?

It changes the text in cell A2 to all uppercase letters. When copied down, it transforms all text in that column to uppercase.

beginner

How can you combine text from two columns into one using Excel formulas?

Use the =A2 & " " & B2 formula to join text from columns A and B with a space between them.

intermediate

What is the purpose of absolute references in column transformations?

Absolute references (using $ signs) keep a cell reference fixed when copying formulas down a column, useful when you want to use a constant value or cell.

Which formula converts text in cell A2 to lowercase?

A =TEXT(A2)

B =UPPER(A2)

C =PROPER(A2)

D =LOWER(A2)

The LOWER function changes all letters in the text to lowercase.

How do you copy a formula down an entire column quickly?

A Drag the fill handle down

B Double-click the fill handle

C Right-click and select copy

D Press Ctrl + Z

Double-clicking the fill handle copies the formula down automatically to match adjacent data length.

What does the formula =A2*10 do when copied down a column?

A Multiplies each value in column A by 10

B Adds 10 to each value in column A

C Divides each value in column A by 10

D Copies the value 10 to each cell

The formula multiplies the value in each cell of column A by 10.

Which symbol is used to make a cell reference absolute in Excel?

A #

B &

C $

D *

The dollar sign ($) fixes the row or column reference in formulas.

What does the formula =CONCATENATE(A2, " ", B2) do?

A Joins text from A2 and B2 with a space

B Converts text to uppercase

C Subtracts B2 from A2

D Adds numbers in A2 and B2

CONCATENATE joins text strings; here it joins A2 and B2 with a space in between.

Explain how to transform a column of names to uppercase in Excel.

Think about text functions and copying formulas.

Describe the difference between relative and absolute references when copying formulas in a column.

Consider what happens when you drag formulas down.

Practice

1. What does the formula =A2 & " " & B2 do when applied in a new column?

easy

A. Adds the numbers in cells A2 and B2

B. Combines the text from cells A2 and B2 with a space between

C. Subtracts the value in B2 from A2

D. Multiplies the values in A2 and B2

Solution

1. Step 1: Understand the & operator in Excel

   The & operator joins (concatenates) text strings together.

2. Step 2: Analyze the formula =A2 & " " & B2

   This formula joins the content of A2, a space " ", and the content of B2 into one text string.

3. Final Answer:

   Combines the text from cells A2 and B2 with a space between -> Option B

4. Quick Check:

   Concatenate text with & = combined text [OK]

Hint: Use & to join text with spaces easily [OK]

Common Mistakes:

• Thinking & adds numbers instead of joining text
• Forgetting to add space between texts
• Using + instead of & for text

2. Which of these formulas correctly converts the text in cell A2 to uppercase in a new column?

easy

A. =UPPER(A2)

B. =PROPER(A2)

C. =LOWER(A2)

D. =TEXT(A2, "UPPER")

Solution

1. Step 1: Identify the function to convert text to uppercase

   The UPPER() function changes all letters in a text string to uppercase.

2. Step 2: Check each option

   LOWER() makes text lowercase, PROPER() capitalizes first letters, TEXT() formats numbers, so only UPPER(A2) is correct.

3. Final Answer:

   =UPPER(A2) -> Option A

4. Quick Check:

   UPPER() = uppercase text [OK]

Hint: Use UPPER() to change text to all caps [OK]

Common Mistakes:

• Using LOWER() instead of UPPER()
• Confusing PROPER() with uppercase
• Trying to use TEXT() for text case

3. Given the data in columns A and B: A2=10, B2=5, what is the result of the formula =A2*B2+2 in a new column?

medium

A. 52

B. 50

C. 12

D. 15

Solution

1. Step 1: Calculate the multiplication part

   Multiply A2 (10) by B2 (5) to get 50.

2. Step 2: Add 2 to the product

   Add 2 to 50, resulting in 52.

3. Final Answer:

   52 -> Option A

4. Quick Check:

   10*5+2 = 52 [OK]

Hint: Multiply first, then add according to order of operations [OK]

Common Mistakes:

• Adding before multiplying (wrong order)
• Confusing cell references
• Ignoring the +2 part

4. You want to create a new column that shows the full name by combining first name in A2 and last name in B2 with a space. Which formula has an error?

medium

A. =A2 & " " & B2

B. =CONCATENATE(A2, " ", B2)

C. =A2 + " " + B2

D. =TEXTJOIN(" ", TRUE, A2, B2)

Solution

1. Step 1: Understand text joining in Excel

   Text strings are joined with & or CONCATENATE or TEXTJOIN functions, not with +.

2. Step 2: Identify the incorrect formula

   Formula D uses + to join text, which causes an error because + is for numbers.

3. Final Answer:

   =A2 + " " + B2 -> Option C

4. Quick Check:

   Use & or CONCATENATE for text, not + [OK]

Hint: Use & or CONCATENATE, never + for text join [OK]

Common Mistakes:

• Using + to join text strings
• Forgetting quotes around space
• Mixing number and text operators

5. You have a column with dates in A2:A10. You want a new column that shows the month name (like "January") for each date. Which formula should you use in B2 and drag down?

hard

A. =MONTH(A2)

B. =YEAR(A2)

C. =DAY(A2)

D. =TEXT(A2, "mmmm")

Solution

1. Step 1: Understand the goal

   You want the full month name, not just the number.

2. Step 2: Check each formula's output

   MONTH() returns month number, DAY() returns day number, YEAR() returns year number. TEXT(A2, "mmmm") converts date to full month name text.

3. Final Answer:

   =TEXT(A2, "mmmm") -> Option D

4. Quick Check:

   TEXT(date, "mmmm") = month name [OK]

Hint: Use TEXT(date, "mmmm") for full month name [OK]

Common Mistakes:

• Using MONTH() which returns number, not name
• Confusing DAY() or YEAR() with month
• Not using quotes correctly in TEXT format
