Loading to worksheet or data model in Excel - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the difference between loading data to a worksheet and loading data to the data model in Excel?

Loading data to a worksheet places the data directly into Excel cells, making it visible and editable. Loading data to the data model stores data in a hidden, compressed database inside Excel, enabling advanced analysis with Power Pivot without cluttering worksheets.

beginner

Why would you choose to load data to the data model instead of a worksheet?

Loading data to the data model allows you to work with large datasets efficiently, create relationships between tables, and use advanced calculations with DAX without slowing down your workbook or filling up worksheets.

How do you load data to the data model using Power Query in Excel?

In Power Query Editor, after preparing your data, click 'Close & Load To...', then select 'Only Create Connection' and check 'Add this data to the Data Model' before clicking OK.

intermediate

What happens if you load data both to a worksheet and the data model?

You get a visible table in the worksheet and the data is also stored in the data model for advanced analysis. This can be useful if you want to see raw data and also use it in Power Pivot or PivotTables connected to the data model.

beginner

Can you edit data directly in the data model?

No, the data model is read-only inside Excel. To change data, you must edit the source or refresh the query. The data model is designed for analysis, not direct editing.

What option should you select in Power Query to load data only to the data model?

A Load to worksheet and data model

B Load to worksheet only

C Create connection only and add to data model

D Load to clipboard

Selecting 'Create connection only' and checking 'Add this data to the Data Model' loads data only to the data model without placing it in a worksheet.

Which of these is NOT a benefit of loading data to the data model?

A Handle large datasets efficiently

B Edit data directly in Excel cells

C Use advanced DAX calculations

D Create relationships between tables

You cannot edit data directly in the data model; it is read-only inside Excel.

If you want to see your data in Excel cells and also use it in Power Pivot, what should you do?

A Load data to both worksheet and data model

B Load data to worksheet only

C Load data to data model only

D Load data to clipboard

Loading data to both worksheet and data model shows data in cells and makes it available for advanced analysis.

What is the main purpose of the Excel data model?

A To enable advanced data analysis and relationships

B To replace worksheets

C To store data for printing

D To edit data faster

The data model stores data for advanced analysis, including relationships and DAX calculations.

How do you refresh data loaded to the data model?

A Restart Excel

B Edit cells directly

C Re-enter data manually

D Refresh the query or data connection

Refreshing the query or data connection updates the data in the data model.

Explain the steps to load data from Power Query to the Excel data model.

Think about the options in the 'Close & Load To...' dialog.

Describe the advantages of loading data to the data model instead of directly to a worksheet.

Consider performance and analysis features.

Practice

1. What is the main difference between loading data to a worksheet and loading data to the data model in Excel?

easy

A. Loading to worksheet displays data as a visible table; loading to data model keeps data hidden but usable for analysis.

B. Loading to worksheet compresses data; loading to data model duplicates data.

C. Loading to worksheet only works with text data; loading to data model only works with numbers.

D. Loading to worksheet automatically creates charts; loading to data model creates pivot tables.

Solution

1. Step 1: Understand worksheet loading

   Loading data to a worksheet shows the data as a visible table you can directly see and use.

2. Step 2: Understand data model loading

   Loading data to the data model keeps the data hidden but ready for advanced analysis like relationships and pivot tables.

3. Final Answer:

   Loading to worksheet displays data as a visible table; loading to data model keeps data hidden but usable for analysis. -> Option A

4. Quick Check:

   Visible table vs hidden model = C [OK]

Hint: Worksheet shows data; data model hides it for analysis [OK]

Common Mistakes:

• Thinking data model shows data as a table
• Confusing data compression with loading method
• Assuming worksheet loading only works with text

2. Which of the following is the correct way to load data into Excel's data model using Power Query?

easy

A. Click 'Close & Load To...' and select 'New Worksheet'.

B. Click 'Close & Load To...' and select 'Table'.

C. Click 'Close & Load To...' and select 'Only Create Connection'.

D. Click 'Close & Load To...' and select 'Pivot Table'.

Solution

1. Step 1: Identify loading to data model option

   Choosing 'Only Create Connection' loads data to the data model without showing it in a worksheet.

2. Step 2: Differentiate from worksheet loading

   Selecting 'Table' or 'New Worksheet' loads data visibly; 'Pivot Table' creates a report but not data model loading.

3. Final Answer:

   Click 'Close & Load To...' and select 'Only Create Connection'. -> Option C

4. Quick Check:

   'Only Create Connection' = data model load [OK]

Hint: Use 'Only Create Connection' to load data model [OK]

Common Mistakes:

• Choosing 'Table' which loads data to worksheet
• Selecting 'Pivot Table' which creates report, not data model
• Confusing 'New Worksheet' with data model loading

3. You load a large sales dataset into Excel using Power Query. You choose 'Only Create Connection' and add it to the data model. What is the expected behavior when you create a PivotTable from this data?

medium

A. PivotTable will fail because data is not loaded into any worksheet.

B. PivotTable will automatically load data into a new worksheet.

C. PivotTable will show an empty table because data is hidden.

D. PivotTable will be created using the data model without loading data into a worksheet.

Solution

1. Step 1: Understand data model loading effect

   Loading data as 'Only Create Connection' adds data to the data model but does not show it in worksheets.

2. Step 2: PivotTable behavior with data model

   PivotTables can use data from the data model directly, so it will create a report without needing worksheet data.

3. Final Answer:

   PivotTable will be created using the data model without loading data into a worksheet. -> Option D

4. Quick Check:

   PivotTable uses data model directly = B [OK]

Hint: PivotTables can use data model without worksheet data [OK]

Common Mistakes:

• Assuming PivotTable needs visible worksheet data
• Thinking PivotTable will fail without worksheet table
• Believing PivotTable auto loads data to worksheet

4. You tried to load data to the data model but accidentally selected 'Table' instead of 'Only Create Connection'. What problem might occur?

medium

A. Data will load to worksheet, increasing file size and slowing performance.

B. Data will not load anywhere and cause an error.

C. Data will load only to the data model but not visible in worksheet.

D. Excel will automatically fix the loading method without user action.

Solution

1. Step 1: Identify effect of loading as 'Table'

   Loading as 'Table' loads data visibly into a worksheet, which can increase file size and slow Excel if data is large.

2. Step 2: Contrast with data model loading

   'Only Create Connection' loads data hidden in data model, avoiding worksheet clutter and performance issues.

3. Final Answer:

   Data will load to worksheet, increasing file size and slowing performance. -> Option A

4. Quick Check:

   Loading as Table = visible data, bigger file [OK]

Hint: Loading as Table shows data, may slow large files [OK]

Common Mistakes:

• Thinking Excel auto fixes loading method
• Believing data won't load if wrong option chosen
• Confusing data model loading with worksheet loading

5. You have multiple large tables to analyze with relationships in Excel. Which loading method should you choose to optimize performance and enable advanced analysis?

hard

A. Load all tables as visible tables in separate worksheets.

B. Load all tables as connections only and add them to the data model.

C. Load half the tables to worksheets and half to data model randomly.

D. Load tables as CSV files outside Excel for analysis.

Solution

1. Step 1: Consider performance with large tables

   Loading large tables as visible worksheets increases file size and slows Excel.

2. Step 2: Use data model for relationships and analysis

   Loading tables as connections only and adding to data model keeps data hidden, improves performance, and allows creating relationships for advanced analysis.

3. Step 3: Avoid random or external loading

   Random loading causes confusion; external CSVs are outside Excel and not integrated.

4. Final Answer:

   Load all tables as connections only and add them to the data model. -> Option B

5. Quick Check:

   Data model + connections = best for large related tables [OK]

Hint: Use data model for large related tables to boost speed [OK]

Common Mistakes:

• Loading all data visibly causing slow Excel
• Mixing loading methods without plan
• Using external files instead of Excel data model
