Consolidating data from multiple sheets in Excel - Dashboard Guide

Dashboard Mode - Consolidating data from multiple sheets

Dashboard Goal

Show total sales from three different store sheets combined into one summary dashboard.

Sample Data

Each sheet has sales data for products sold in different stores.

Product	Sales
Apples	100
Bananas	150
Cherries	200

Sheet Names and Data:

• Store1: Apples 100, Bananas 150, Cherries 200
• Store2: Apples 120, Bananas 130, Cherries 210
• Store3: Apples 110, Bananas 140, Cherries 190

Dashboard Components

• Component 1: Consolidated Sales Table
  Shows total sales per product from all stores combined.
  Formula example for Apples total sales:
  =Store1!B2 + Store2!B2 + Store3!B2
  Result for Apples: 330
• Component 2: Total Sales KPI
  Sum of all sales from all products and stores.
  Formula:
  =SUM(Store1!B2:B4) + SUM(Store2!B2:B4) + SUM(Store3!B2:B4)
  Result: 1350
• Component 3: Bar Chart
  Visualizes total sales per product from the consolidated table.

Dashboard Layout

+-------------------------+------------------+
| Consolidated Sales Table | Total Sales KPI  |
| (Product and Total Sales)| (Big number)     |
+-------------------------+------------------+
|                         Bar Chart              |
|               (Sales per Product)              |
+-----------------------------------------------+

Interactivity

Add a filter to select a specific product. When a product is selected, the consolidated sales table and bar chart update to show only that product's sales. The total sales KPI updates to show the sum for the selected product across all stores.

Self Check

If you add a filter to show only "Bananas", which components update and what values do they show?

• Consolidated Sales Table: Shows only Bananas with total sales 150 + 130 + 140 = 420
• Total Sales KPI: Updates to 420
• Bar Chart: Shows a single bar for Bananas with height 420

Key Result

Dashboard consolidates sales data from three store sheets to show total sales per product and overall total.

Practice

1. What is the main purpose of consolidating data from multiple sheets in Excel?

easy

A. To combine data from different sheets into one summary

B. To delete duplicate sheets automatically

C. To create charts from a single sheet only

D. To protect sheets with passwords

Solution

1. Step 1: Understand consolidation concept

   Consolidation means combining data from multiple sheets to get a summary.

2. Step 2: Identify the purpose

   It helps to see combined totals or summaries in one place.

3. Final Answer:

   To combine data from different sheets into one summary -> Option A

4. Quick Check:

   Consolidate = Combine data [OK]

Hint: Think 'combine' when you hear consolidate [OK]

Common Mistakes:

• Confusing consolidation with deleting sheets
• Thinking it only creates charts
• Assuming it protects sheets

2. Which formula correctly sums cell A1 from sheets named Sheet1, Sheet2, and Sheet3?

easy

A. =SUM(Sheet1!A1, Sheet2!A1, Sheet3!A1)

B. =SUM(A1:Sheet3!A1)

C. =SUM(Sheet1:A1, Sheet2:A1, Sheet3:A1)

D. =SUM(Sheet1!A1:A3)

Solution

1. Step 1: Understand sheet references in formulas

   To sum cells from different sheets, use sheetname!cell syntax separated by commas.

2. Step 2: Check each option

   =SUM(Sheet1!A1, Sheet2!A1, Sheet3!A1) correctly sums A1 from each sheet individually.

3. Final Answer:

   =SUM(Sheet1!A1, Sheet2!A1, Sheet3!A1) -> Option A

4. Quick Check:

   SUM(sheet!cell, ...) = correct [OK]

Hint: Use sheetname!cell for cross-sheet references [OK]

Common Mistakes:

• Using range syntax across sheets incorrectly
• Missing exclamation mark after sheet name
• Trying to sum ranges that don't exist

3. Given Sheet1!A1=10, Sheet2!A1=20, Sheet3!A1=30, what is the result of =SUM(Sheet1!A1:Sheet3!A1)?

medium

A. 60

B. 10

C. Syntax Error

D. #REF! error

Solution

1. Step 1: Understand range syntax across sheets

   Excel does not allow ranges like Sheet1!A1:Sheet3!A1 across multiple sheets in SUM.

2. Step 2: Identify the error

   This causes a #REF! error because the range is invalid.

3. Final Answer:

   #REF! error -> Option D

4. Quick Check:

   Invalid cross-sheet range = #REF! error [OK]

Hint: Cross-sheet ranges like Sheet1!A1:Sheet3!A1 cause errors [OK]

Common Mistakes:

• Assuming cross-sheet ranges work like normal ranges
• Expecting sum of all values without correct syntax
• Ignoring error messages

4. You want to sum cell B2 from sheets Jan, Feb, and Mar using =SUM(Jan!B2, Feb!B2, Mar!B2), but it returns 0. What is the likely problem?

medium

A. Formula syntax is incorrect

B. Sheet names are misspelled or missing

C. Cells B2 are empty in all sheets

D. SUM function cannot add multiple sheets

Solution

1. Step 1: Check sheet names in formula

   If sheet names are misspelled or do not exist, Excel treats references as zero.

2. Step 2: Verify cell contents

   If cells have values but formula returns 0, likely sheet names are wrong.

3. Final Answer:

   Sheet names are misspelled or missing -> Option B

4. Quick Check:

   Wrong sheet names = zero result [OK]

Hint: Double-check sheet names spelling in formulas [OK]

Common Mistakes:

• Assuming syntax error instead of name error
• Not verifying cell contents
• Thinking SUM can't add multiple sheets

5. You have monthly sales data in sheets named Jan, Feb, Mar in cell C5. You want a summary sheet cell A1 to show total sales for these months. Which formula correctly consolidates this data?

hard

A. =SUM(Jan:C5, Feb:C5, Mar:C5)

B. =SUM('Jan:Mar'!C5)

C. =SUM(Jan:Mar!C5)

D. =SUM(Jan!C5:Mar!C5)

Solution

1. Step 1: Understand 3D reference syntax

   Using Jan:Mar!C5 sums cell C5 across all sheets from Jan through Mar.

2. Step 2: Check each option

   =SUM(Jan:Mar!C5) uses correct 3D reference syntax without quotes.

3. Final Answer:

   =SUM(Jan:Mar!C5) -> Option C

4. Quick Check:

   3D reference = SUM(Jan:Mar!C5) [OK]

Hint: Use 3D references like Jan:Mar!Cell to sum across sheets [OK]

Common Mistakes:

• Adding quotes around sheet range
• Using invalid range syntax across sheets
• Trying to sum ranges instead of single cells
