UPPER, LOWER, PROPER in Google Sheets - Dashboard Guide

Dashboard Mode - UPPER, LOWER, PROPER

Dashboard Goal

This dashboard helps you clean and standardize names by changing text to all uppercase, all lowercase, or proper case (first letter capitalized).

Sample Data

Original Name
alice johnson
BOB SMITH
cHaRLie bRoWn
diana prince
eVa GREEN

Dashboard Components

• Uppercase Names: Converts all letters to uppercase.
  Formula example: =UPPER(A2) applied to each name.
  Result for 'alice johnson' is 'ALICE JOHNSON'.
• Lowercase Names: Converts all letters to lowercase.
  Formula example: =LOWER(A2) applied to each name.
  Result for 'BOB SMITH' is 'bob smith'.
• Proper Case Names: Capitalizes the first letter of each word.
  Formula example: =PROPER(A2) applied to each name.
  Result for 'cHaRLie bRoWn' is 'Charlie Brown'.

Interactivity

You can add a filter to select specific names (for example, filter by names containing 'a'). When you filter the original names, the uppercase, lowercase, and proper case columns update automatically to show only the filtered names.

Self Check

If you add a filter to show only names containing the letter 'e', which names appear in the Proper Case Names column?

Answer: 'alice johnson', 'diana prince', and 'eVa GREEN' appear as 'Alice Johnson', 'Diana Prince', and 'Eva Green'.

Key Result

Dashboard to convert names into uppercase, lowercase, and proper case for easy text cleaning.

Practice

1. What does the UPPER function do in Google Sheets?

easy

A. Reverses the text string.

B. Converts all letters in a text to lowercase.

C. Capitalizes only the first letter of the first word.

D. Converts all letters in a text to uppercase.

Solution

1. Step 1: Understand the UPPER function

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

2. Step 2: Compare with other options

   LOWER changes letters to lowercase, PROPER capitalizes first letters of each word, and reversing text is unrelated.

3. Final Answer:

   Converts all letters in a text to uppercase. -> Option D

4. Quick Check:

   UPPER = all uppercase [OK]

Hint: UPPER = all caps, LOWER = all small, PROPER = first letters caps [OK]

Common Mistakes:

• Confusing UPPER with LOWER function
• Thinking PROPER only capitalizes first word
• Assuming UPPER reverses text

2. Which of the following is the correct syntax to convert cell A1 text to lowercase in Google Sheets?

easy

A. =LOWER A1

B. =LOWER(A1)

C. =LOWER(A1;

D. =LOWER{A1}

Solution

1. Step 1: Recall correct function syntax

   Functions require parentheses around arguments, so LOWER(A1) is correct.

2. Step 2: Check other options for syntax errors

   =LOWER A1 misses parentheses, C has a wrong closing bracket, D uses curly braces incorrectly.

3. Final Answer:

   =LOWER(A1) -> Option B

4. Quick Check:

   Correct syntax uses parentheses [OK]

Hint: Functions always use parentheses around arguments [OK]

Common Mistakes:

• Omitting parentheses
• Using wrong brackets or braces
• Adding extra characters like semicolons

3. Given cell A1 contains the text "hello world", what will the formula =PROPER(A1) return?

medium

A. "Hello World"

B. "HELLO WORLD"

C. "hello world"

D. "Hello world"

Solution

1. Step 1: Understand PROPER function behavior

   PROPER capitalizes the first letter of each word in the text.

2. Step 2: Apply PROPER to "hello world"

   Both "hello" and "world" get their first letters capitalized, resulting in "Hello World".

3. Final Answer:

   "Hello World" -> Option A

4. Quick Check:

   PROPER("hello world") = "Hello World" [OK]

Hint: PROPER capitalizes first letter of each word [OK]

Common Mistakes:

• Confusing PROPER with UPPER or LOWER
• Capitalizing only first word
• Leaving text unchanged

4. You want to convert the text in cell B2 to uppercase, but your formula =upper B2 returns an error. What is the fix?

medium

A. Use =UPPER[B2] with square brackets.

B. Add quotes around B2 like =UPPER("B2").

C. Change to =UPPER(B2) with uppercase function name.

D. Remove parentheses like =UPPER B2.

Solution

1. Step 1: Check function name case sensitivity

   Best practice is to use uppercase for function names like UPPER, and parentheses are required around cell references.

2. Step 2: Identify syntax error

   Options A-D: A uses invalid brackets, B treats B2 as literal text, C lacks parentheses.

3. Step 3: Correct formula syntax

   Using =UPPER(B2) is correct and standard.

4. Final Answer:

   Change to =UPPER(B2) with uppercase function name. -> Option C

5. Quick Check:

   Use =UPPER(cell) syntax [OK]

Hint: Use =UPPER(cell) with parentheses, no quotes or brackets [OK]

Common Mistakes:

• Adding quotes around cell references
• Using square brackets instead of parentheses
• Omitting parentheses

5. You have a list of names in column A with inconsistent capitalization, like "jAnE doE" and "mARk tWain". Which formula in cell B1 will correctly format the name in A1 to proper case, and how would you apply it to the whole column?

hard

A. In B1: =PROPER(A1), then drag the fill handle down to apply to all rows.

B. In B1: =UPPER(A1), then copy and paste values down.

C. In B1: =LOWER(A1), then drag down to apply.

D. In B1: =PROPER(A:A1) to apply to entire column at once.

Solution

1. Step 1: Choose correct function for capitalization

   PROPER capitalizes the first letter of each word, fixing inconsistent capitalization.

2. Step 2: Apply formula to first cell and extend

   Enter =PROPER(A1) in B1, then drag the fill handle down to copy the formula for all rows.

3. Step 3: Understand why other options fail

   UPPER makes all letters uppercase, LOWER all lowercase, and =PROPER(A1:A) is invalid syntax for array formula here.

4. Final Answer:

   In B1: =PROPER(A1), then drag the fill handle down. -> Option A

5. Quick Check:

   Use PROPER + drag fill for column [OK]

Hint: Use PROPER and drag down to fix capitalization in lists [OK]

Common Mistakes:

• Using UPPER or LOWER instead of PROPER
• Trying to apply PROPER to whole column without dragging
• Using incorrect array syntax
