AutoFill for formula copying in Google Sheets - Dashboard Guide

Dashboard Mode - AutoFill for formula copying

Goal

Calculate total sales for each product by copying a formula down the column automatically.

Sample Data

Product	Price	Quantity Sold	Total Sales
Apples	2	30
Bananas	1	50
Cherries	3	20
Dates	5	10
Elderberries	4	15

Dashboard Components

• KPI Card: Total Revenue calculated with formula =SUM(D2:D6) showing total sales of all products.
• Data Table: Shows products with columns for Price, Quantity Sold, and Total Sales.
• Formula in Total Sales Column: In cell D2 enter =B2*C2 and use AutoFill to copy this formula down to D3:D6. This calculates total sales per product.

Dashboard Layout

+----------------------+------------------+
|      Data Table       |   Total Revenue  |
|  (Products & Sales)   |     (KPI Card)   |
+----------------------+------------------+

Interactivity

When you update Price or Quantity Sold for any product, the Total Sales column updates automatically because the formula is copied down using AutoFill. The Total Revenue KPI card also updates to reflect the new total.

Self Check

If you change the Quantity Sold for Bananas from 50 to 60, which cells update and what is the new Total Revenue?

Answer: Cell D3 updates to =B3*C3 = 1*60 = 60. The Total Revenue cell updates to sum all Total Sales: 2*30 + 60 + 3*20 + 5*10 + 4*15 = 60 + 60 + 60 + 50 + 60 = 290.

Key Result

Dashboard shows product sales with AutoFill formula calculating total sales and a KPI card summing total revenue.

Practice

1. What happens to cell references when you use AutoFill to copy a formula down a column in Google Sheets?

easy

A. Formulas are deleted after copying.

B. Cell references stay exactly the same without changing.

C. Cell references adjust automatically to refer to the next rows.

D. Only text values are copied, not formulas.

Solution

1. Step 1: Understand AutoFill behavior

   When you drag the fill handle down, Google Sheets copies the formula to new cells.

2. Step 2: Observe cell reference adjustment

   Relative cell references change to match the new row numbers automatically.

3. Final Answer:

   Cell references adjust automatically to refer to the next rows. -> Option C

4. Quick Check:

   AutoFill changes relative references [OK]

Hint: AutoFill changes relative references automatically [OK]

Common Mistakes:

• Thinking references stay fixed without $
• Believing formulas get deleted
• Confusing values with formulas

2. Which of these formulas will keep the reference to cell A1 fixed when copied down using AutoFill?

easy

A. =$A$1+10

B. =$A1+10

C. =A$1+10

D. =A1+10

Solution

1. Step 1: Identify absolute reference syntax

   Using $ before column and row fixes the reference completely.

2. Step 2: Check each option

   =$A$1+10 uses $A$1 which fixes both column A and row 1, so it won't change when copied.

3. Final Answer:

   =$A$1+10 -> Option A

4. Quick Check:

   Use $ before column and row to fix reference [OK]

Hint: Use $ before column and row to fix reference [OK]

Common Mistakes:

• Using only one $ fixes only part of the reference
• Forgetting $ causes reference to shift
• Confusing relative and absolute references

3. If cell B2 contains the formula =A2*2 and you drag the fill handle down to B4, what will be the formula in cell B4?

medium

A. =A2*2

B. =A4*2

C. =B2*2

D. =A3*2

Solution

1. Step 1: Understand relative reference adjustment

   The formula in B2 uses A2, a relative reference that changes row number when copied down.

2. Step 2: Calculate new reference in B4

   Copying down two rows changes A2 to A4 in B4.

3. Final Answer:

   =A4*2 -> Option B

4. Quick Check:

   Relative references update row numbers when copied down [OK]

Hint: Relative references update row numbers when copied down [OK]

Common Mistakes:

• Assuming reference stays at A2
• Mixing column and row references
• Copying formula without dragging fill handle

4. You tried to copy the formula =SUM(A1:A3) down a column using AutoFill, but the range did not adjust as expected. What is the likely problem?

medium

A. You forgot to press Enter after typing the formula.

B. AutoFill does not work with SUM formulas.

C. The formula contains a syntax error.

D. The range uses absolute references like $A$1:$A$3.

Solution

1. Step 1: Check the range references in the formula

   If the range uses $ signs like $A$1:$A$3, it is fixed and won't change when copied.

2. Step 2: Understand AutoFill behavior with fixed ranges

   AutoFill copies the formula exactly if references are absolute, so the range stays the same.

3. Final Answer:

   The range uses absolute references like $A$1:$A$3. -> Option D

4. Quick Check:

   Absolute ranges do not adjust when copied [OK]

Hint: Check for $ in ranges to see if they are fixed [OK]

Common Mistakes:

• Assuming AutoFill can't copy SUM formulas
• Ignoring $ signs in ranges
• Thinking syntax error causes range not to adjust

5. You have a formula in cell C2: =IF(A2>10, B2*2, B2/2). You want to copy it down to C10 using AutoFill, but keep the reference to column B fixed while allowing the row number to change. Which formula should you enter in C2 before AutoFill?

hard

A. =IF(A2>10, $B2*2, $B2/2)

B. =IF(A2>10, B$2*2, B$2/2)

C. =IF(A2>10, $B$2*2, $B$2/2)

D. =IF(A2>10, B2*2, B2/2)

Solution

1. Step 1: Understand fixing column but not row

   To fix column B but allow row to change, use $ before column only: $B2.

2. Step 2: Check each option

   =IF(A2>10, $B2*2, $B2/2) uses $B2 which fixes column B and allows row to update when copied down.

3. Final Answer:

   =IF(A2>10, $B2*2, $B2/2) -> Option A

4. Quick Check:

   Use $ before column only to fix column in references [OK]

Hint: Use $ before column only to fix column, row changes [OK]

Common Mistakes:

• Fixing both column and row with $B$2
• Fixing row instead of column with B$2
• Not using $ at all causes column to shift
