Number formats (currency, percentage, date) in Google Sheets - Cell-by-Cell Formula Trace

Sample Data

Column A contains raw numbers: 1000 (a number), 0.25 (a decimal), and 44927 (a date serial number). Column B will show these numbers formatted as currency, percentage, and date respectively.

Cell	Value
A1	1000
A2	0.25
A3	44927
B1	1000
B2	0.25
B3	44927

Formula Trace

=TEXT(B1, "$#,##0.00") & ", " & TEXT(B2, "0.00%") & ", " & TEXT(B3, "mm/dd/yyyy")

Step 1: TEXT(B1, "$#,##0.00")

Step 2: TEXT(B2, "0.00%")

Step 3: TEXT(B3, "mm/dd/yyyy")

Step 4: "$1,000.00" & ", " & "25.00%" & ", " & "12/31/2022"

Cell Reference Map

    A       B
1 | 1000  | 1000  
2 | 0.25  | 0.25

Arrows: B1 -> TEXT currency, B2 -> TEXT percentage, B3 -> TEXT date

Cells B1, B2, and B3 are referenced for formatting as currency, percentage, and date respectively.

Result

    A       B       C
1 | 1000  | 1000  | $1,000.00, 25.00%, 12/31/2022
2 | 0.25  | 0.25  |

Cell C1 shows the combined formatted output: currency for B1, percentage for B2, and date for B3.

Sheet Trace Quiz - 3 Questions

What does the formula TEXT(B1, "$#,##0.00") produce when B1 is 1000?

A "1000"

B "$1,000.00"

C "$1000"

D "1,000.00"

Key Result

TEXT(value, format_text) converts numbers to text with specified number formats like currency, percentage, or date.

Practice

1. What does applying the Percentage number format to a cell do in Google Sheets?

easy

A. It changes the number into a date format.

B. It converts the number into currency with a $ sign.

C. It shows the number as a part of 100 with a % sign.

D. It rounds the number to the nearest whole number.

Solution

1. Step 1: Understand Percentage Format

   The percentage format multiplies the number by 100 and adds a % sign to show parts of 100.

2. Step 2: Compare with Other Formats

   Currency adds a $ sign, date changes to calendar format, rounding changes number value, so these are incorrect.

3. Final Answer:

   It shows the number as a part of 100 with a % sign. -> Option C

4. Quick Check:

   Percentage format = parts of 100 [OK]

Hint: Percentage format shows numbers as % of 100 [OK]

Common Mistakes:

• Thinking percentage changes the number value
• Confusing percentage with currency format
• Assuming percentage rounds numbers

2. Which of the following is the correct way to format a cell as currency in Google Sheets?

easy

A. Select the cell, then click Format > Number > Currency.

B. Type a $ sign before the number in the cell.

C. Use the formula =CURRENCY(A1).

D. Change the cell font color to green.

Solution

1. Step 1: Identify Currency Formatting Method

   In Google Sheets, currency format is applied via the menu: Format > Number > Currency.

2. Step 2: Evaluate Other Options

   Typing $ manually does not format the cell; no =CURRENCY formula exists; font color change does not affect number format.

3. Final Answer:

   Select the cell, then click Format > Number > Currency. -> Option A

4. Quick Check:

   Currency format applied via Format menu [OK]

Hint: Use Format > Number > Currency to format money [OK]

Common Mistakes:

• Typing $ manually instead of formatting
• Trying to use a non-existent formula
• Changing font color instead of number format

3. If cell A1 contains the number 0.25 and you apply the Percentage format, what will the cell display?

medium

A. 25%

B. 1/4/1900

C. $0.25

D. 0.25

Solution

1. Step 1: Understand Percentage Formatting

   Applying percentage format multiplies the number by 100 and adds a % sign. So 0.25 becomes 25%.

2. Step 2: Check Other Formats

   0.25 is the raw number, $0.25 is currency, and 1/4/1900 is a date format interpretation, so these are incorrect.

3. Final Answer:

   25% -> Option A

4. Quick Check:

   0.25 as percentage = 25% [OK]

Hint: Percentage format multiplies by 100 and adds % [OK]

Common Mistakes:

• Expecting the number to stay the same
• Confusing currency and percentage formats
• Thinking date format applies automatically

4. You entered the date 12/31/2023 in a cell, but it shows as 44926. What should you do to fix this?

medium

A. Increase the font size to make the date visible.

B. Re-enter the date with dashes instead of slashes.

C. Use the formula =DATE(2023,12,31) instead.

D. Change the cell format to Date via Format > Number > Date.

Solution

1. Step 1: Understand Date Storage

   Google Sheets stores dates as numbers (days since 12/30/1899). 44926 is the number for 12/31/2023.

2. Step 2: Apply Date Format

   To see the date instead of the number, change the cell format to Date via Format > Number > Date.

3. Final Answer:

   Change the cell format to Date via Format > Number > Date. -> Option D

4. Quick Check:

   Date format shows calendar date, not serial number [OK]

Hint: Change format to Date to see calendar dates, not numbers [OK]

Common Mistakes:

• Re-entering date instead of formatting
• Using formulas unnecessarily
• Changing font size instead of format

5. You have a list of prices in column A as numbers (e.g., 12.5, 7.99). You want to show them as US dollars with two decimals and a $ sign. Which steps will achieve this correctly?

hard

A. Use the formula =TEXT(A1, "$0.00") in a new column.

B. Select column A, then Format > Number > Currency, and set decimal places to 2.

C. Type $ before each number manually and round to 2 decimals.

D. Change the cell format to Percentage and multiply by 100.

Solution

1. Step 1: Apply Currency Format

   Select the cells and use Format > Number > Currency to add $ sign and currency style.

2. Step 2: Set Decimal Places

   Adjust decimal places to 2 to show cents properly.

3. Final Answer:

   Select column A, then Format > Number > Currency, and set decimal places to 2. -> Option B

4. Quick Check:

   Currency format + 2 decimals = correct money display [OK]

Hint: Use Format > Number > Currency and set decimals to 2 [OK]

Common Mistakes:

• Typing $ manually instead of formatting
• Using percentage format by mistake
• Using TEXT formula unnecessarily
