Basic Excel Interview Questions For Freshers

When preparing for a Microsoft Excel interview, you should have a solid understanding of basic, intermediate, and advanced features of MS Excel. Interviewers will assess your familiarity with Excel through various advanced and basic Excel interview questions. 

Below are the essential concepts that will help you ace your next Excel interview.

1. What Is A Cell In Excel And How Is It Identified?

A cell in Excel is the basic unit where data is entered. It is the intersection of a row and a column, and each cell has a unique reference composed of a column letter and a row number. For example, A1 refers to the cell in the first column (A) and the first row (1).

In more complex spreadsheets, you may have hundreds of rows and columns, creating a vast grid of cells. These cells can store various types of data, including numbers, text, dates, and formulas.

Cells are essential when performing calculations and organizing data. For example, if you wanted to calculate the total sales from cells A2 through A10, you would use the formula: =SUM(A2:A10)

This formula uses the cell references in the specified range to calculate the total. The cell reference allows Excel to track and reference the data contained within it, which is crucial for applying formulas and functions in large spreadsheets.

2. How To Do Data Entry In Excel?

When entering data into Excel, it's important to consider both efficiency and accuracy. Here are multiple ways to handle data entry:

Manual Entry: Click on any cell to select it. Once selected, you can type text, numbers, or formulas. Press Enter to move down to the next cell or Tab to move to the next cell to the right.

Auto-Fill: To fill a series (e.g., dates, months, numbers), type the first two values in adjacent cells, select them, and drag the fill handle (a small square in the bottom-right corner of the selection) to extend the series.

Shortcuts:

• Ctrl + D: Fills the selected cell with the value from the cell above.
• Ctrl + R: Fills the selected cell with the value from the cell to the left.

Data Importing: If data is available in external sources (e.g., CSV files), use Data > Get External Data > From Text to import data directly into Excel.

3. What Are The 5 Basic Functions Of Excel?

Excel offers a wide variety of functions, but the following five basic functions are most commonly used:

• SUM: Adds a range of numbers. Example: =SUM(A1:A5) adds the values in cells A1 through A5.
• AVERAGE: Calculates the average of a range. Example: =AVERAGE(B1:B10) gives the average of values in cells B1 through B10.
• MIN: Finds the minimum value in a range. Example: =MIN(C1:C7) returns the lowest value in the range C1 to C7.
• MAX: Finds the maximum value in a range. Example: =MAX(D1:D8) returns the highest value in the range D1 to D8.
• COUNT: Counts the number of cells with numeric data. Example: =COUNT(E1:E5) counts how many cells in the range E1 to E5 contain numbers.
• COUNTA: Counts all non-blank cells. Example: =COUNTA(F1:F10) counts all non-empty cells in the range F1 to F10.
• LEN: Counts the number of characters in a cell. Example: =LEN(G1) returns the number of characters in the content of cell G1.

4. How Do You Use A Formula In Excel To Perform Basic Calculations?

To use a formula in Excel, start with an equal sign ("="). For addition, use +, for subtraction -, multiplication *, and division /. Proficiency in formulas is a must, as basic Excel interview questions often include some related to these operations.

For example, =A1+A2 adds the values in A1 and A2. These basic formulas allow quick calculations by referencing cell values, making Excel an essential tool for efficient data analysis and operations.

5. What Is The Difference Between A Formula And A Function In Excel?

A formula in Excel is a custom calculation created by the user. It can include a variety of operators and cell references. For example: =A1+B1 adds the values in cells A1 and B1.

A function, on the other hand, is a predefined operation in Excel that simplifies common calculations. For example, =SUM(A1:A5) adds the values within the range A1 to A5.

To go a step further, formulas can combine functions for more complex calculations. For instance, =SUM(A1:A5)/COUNTA(B1:B5) calculates the total sum of values in A1 to A5 and divides it by the count of non-empty cells in B1 to B5. This combination of functions within a formula allows for more powerful and customized calculations in Excel.

These advanced features allow for deeper insights and more customized data analysis.

22. How Does The Sumif Function Work, And When Would You Use It?

The SUMIF function allows you to sum values based on a specified condition. It follows this syntax:

SUMIF(range, criteria, [sum_range])

• Range: The cells that you evaluate with the condition.
• Criteria: The condition that defines which cells will be summed.
• Sum_range: The cells to sum (if omitted, Excel sums the range).

For example, if you want to sum the sales for a particular region, you can use the SUMIF function: =SUMIF(A2:A10, "East", B2:B10)

23. How Can You Sort Data In Excel By Multiple Columns?

Sorting by multiple columns helps to organize data in a logical and readable manner. Excel allows you to sort by more than one column simultaneously.

1. Select your data.
2. Click on the “Data” tab and select “Sort.”
3. In the Sort dialog box, add levels for each column you want to sort by.

For example, if you have a sales dataset with columns for Region and Sales Amount, you can sort first by Region and then by Sales Amount within each region.

24. What Is The If Function In Excel, And How Is It Used?

The IF function in Excel is used to perform logical tests and return different values depending on whether the test evaluates to true or false. The syntax is:

=IF(logical_test, value_if_true, value_if_false)

For instance, to categorize sales as "High" or "Low" based on a threshold, you can use the formula:

=IF(B2>1000, "High", "Low")

For more complex logical tests, you can nest IF functions or combine them with AND/OR. For example, to categorize sales as "High", "Medium", or "Low" based on multiple conditions, you could use a nested IF formula like this:

=IF(B2>2000, "High", IF(B2>1000, "Medium", "Low"))

Alternatively, using AND/OR within an IF function allows for more complex conditions, such as:

=IF(AND(B2>1000, C2<500), "High", "Low")

This formula checks if sales are over 1000 and the cost is under 500 before returning the result.

25. How Do You Use The Hlookup Function In Excel?

The HLOOKUP function searches for a value in the top row of a table and returns a value in the same column from a specified row. It follows the

 syntax: =HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup])

For example, if you have a table where row 1 contains product names, and row 2 contains their prices, you can use HLOOKUP to find the price of a

 product: =HLOOKUP("Product A", A1:D2, 2, FALSE)

26. What Is A Macro In Excel, And How Can You Record One?

A Macro in Excel is a set of actions or commands that can be recorded and executed with a single click. It automates repetitive tasks, making your workflow more efficient. To record a macro:

1. Go to the View tab and select Macros.
2. Click Record Macro.
3. Perform the actions you want to automate.
4. Stop recording when done.

Macros are essential for automating complex tasks. For example, you could record a macro that formats data in a specific way or applies a series of filters to your dataset.

For advanced automation, you can modify recorded macros using the Visual Basic for Applications (VBA) editor. Access it by clicking Developer > Visual Basic. In the editor, you can fine-tune the code generated by your macro or write custom VBA code for more complex operations. This makes macros more flexible and powerful for automation.

27. How Can You Protect A Worksheet From Being Modified Or Copied?

What-If Analysis allows you to explore different scenarios in Excel by changing input values and observing the results. Excel provides three types of What-If Analysis tools:

1. Scenario Manager: Create different scenarios based on varying input values.

2. Goal Seek: Find the input needed to achieve a desired output.

3. Data Table: Analyze how changes in one or two variables affect results.

Fun Facts About Excel: In Excel 2007 and later versions, a worksheet can contain up to 1,048,576 rows and 16,384 columns.

29. How Can You Calculate The Average Of A Set Of Numbers In Excel?

To calculate the average, use the AVERAGE function, which follows this syntax: 

=AVERAGE(number1, [number2], …)

For example, to calculate the average sales from cells B2 to B10, the formula would be:

=AVERAGE(B2:B10)

30. What Are The Different Types Of Cell References In Excel, And How Do They Differ?

There are three main types of cell references in Excel, each serving a specific purpose when working with formulas:

1. Relative Reference (e.g., A1):
This is the default reference type in Excel. When you copy a formula containing a relative reference to another cell, the reference updates based on its new position. For example, if a formula in B1 is =A1 and you copy it to B2, it becomes =A2. This is useful when applying the same calculation across rows or columns.

2. Absolute Reference (e.g., $A$1):
Absolute references stay fixed no matter where the formula is copied. Both the column (A) and the row (1) are locked. If your formula references a specific cell like a tax rate or constant value, using $A$1 ensures it always points to that exact cell, avoiding accidental shifts during copying.

3. Mixed Reference (e.g., A$1 or $A1):
Mixed references lock either the row or the column—but not both. A$1 locks the row (1 stays fixed), while $A1 locks the column (A stays fixed). These are helpful in structured calculations like multiplication tables or complex lookups, where one dimension should remain constant as the formula is dragged across the sheet.

31. What Is The Purpose Of Using A Pivot Table Slicer In Excel?

A slicer is a visual filter used to filter data in pivot tables interactively. It provides buttons for each category, making it easier to filter by a specific field.

For example, if you have a pivot table showing sales by product and region, you can add a slicer to filter the data by region, allowing you to analyze sales in one region at a time.

Using slicers enhances your ability to interact with pivot tables efficiently.

32. How Do You Use Excel’s Find And Replace Feature?

The Find and Replace feature is used to search for specific data and replace it with another value.

1. Press Ctrl + F to open the Find and Replace dialog.
2. Enter the value you want to find.
3. Click on “Replace” and enter the new value.

This feature is particularly useful when cleaning and preparing data.

33. How Can You Debug A Vba Code In Excel?

To debug a VBA code:

1. Open the VBA editor (Alt + F11).
2. Set breakpoints by clicking in the margin of the code window.
3. Step through the code using the “F8” key.
4. Use the Immediate Window to evaluate expressions or print variable values.

Debugging VBA code is essential for resolving errors in custom Excel functions or automating tasks with macros.

34. What Are The Differences Between Substitute And Replace Functions In Excel?

Both SUBSTITUTE and REPLACE functions are used to replace text in Excel, but they work differently:

• SUBSTITUTE: Replaces occurrences of a specific substring within a text string. Example:

   =SUBSTITUTE("Hello World", "World", "Excel") → "Hello Excel"

• REPLACE: Replaces part of a string based on position. Example:

   =REPLACE("Hello World", 7, 5, "Excel") → "Hello Excel"

35. How Do You Check Whether A Pivot Table Has Been Modified?

You can check if a Pivot Table has been modified by examining its refresh status or by using the "Change Data Source" option. If the Pivot Table data source has changed, it will no longer be linked to the original dataset.

Checking the status of pivot tables is essential for maintaining data integrity and ensuring reports are up-to-date.

2. Cell Locking: This method allows you to lock specific cells in the workbook while leaving others editable. Once the worksheet is protected, users can only edit unlocked cells.

3. Sheet Protection: With sheet protection, you can restrict actions like editing, formatting, or deleting content in a specific sheet. You can set this option by right-clicking on a sheet tab and selecting "Protect Sheet."

39. How Does Excel Calculate Compound Interest Using A Formula?

Calculating compound interest in Excel can be done easily using the FV (Future Value) function. The formula is structured as follows:

=FV(rate, nper, pmt, [pv], [type])

• rate: The interest rate per period.
• nper: The number of periods.
• pmt: The payment made each period.
• pv: The present value or principal amount.
• type: The timing of payments (0 for end of period, 1 for beginning).

For example, if you want to calculate compound interest on a principal of INR 1,000 with an interest rate of 5% annually for 5 years, you would use:

=FV(5%, 5, 0, -1000)

This returns the future value of your investment, including compound interest.

40. How Do You Differentiate Between A Function And A Subroutine In Vba?

In VBA (Visual Basic for Applications), a function and a subroutine are both used to perform tasks, but they differ in their purpose and structure:

• Function: A function performs a specific task and returns a value. You can use the returned value in other parts of your code or in Excel formulas. For example:

Function CalculateSum(a As Double, b As Double) As Double
    CalculateSum = a + b
End Function

• Subroutine: A subroutine, often referred to as a "Sub," performs actions but does not return a value. It is used to execute a series of commands without providing a result. For example:

Sub DisplayMessage()
    MsgBox "Hello, world!"
End Sub

The key difference lies in whether the code returns a result or just performs an action.

41. What Is The Lookup Function In Excel, And When Would You Use It?

The LOOKUP function in Excel allows you to search for a value in a range or array and return a corresponding value from another range. You would use it when you need to find information that matches a specific condition.

For example, if you have a list of employee names in column A and their salaries in column B, and you need to look up the salary of a specific employee, you could use the formula: 

=LOOKUP("John", A2:A10, B2:B10)

However, unlike VLOOKUP, which searches only vertically across columns, LOOKUP can search both horizontally and vertically. This makes LOOKUP more versatile in certain scenarios. While VLOOKUP requires the lookup value to be in the first column, LOOKUP allows greater flexibility in how you arrange your data, making it suitable for both row-based and column-based searches.

42. How Do You Pass Arguments To Vba Functions In Excel?

In VBA, you pass arguments to a function by specifying them within the parentheses. These arguments can be variables, constants, or even expressions. For example, the following function takes two arguments and returns their sum:

Function AddNumbers(num1 As Double, num2 As Double) As Double
    AddNumbers = num1 + num2
End Function

You can then call this function with specific arguments:

Sub TestFunction()
    MsgBox AddNumbers(5, 10)
End Sub

This will display a message box showing the sum of 5 and 10.

43. How Can You Use Excel’s Power Query To Transform Data, And What Are The Advantages Of Using It Over Traditional Methods Like Formulas Or Pivot Tables?

Power Query in Excel allows you to import, clean, and transform large datasets with ease. It provides a user-friendly interface for reshaping data, filtering, grouping, and merging without complex formulas.

To check for errors in a Pivot Table calculation, you should:

1. Look for any cells that display the error messages, such as #DIV/0!, #REF!, or #N/A.
2. Use the "Error Checking" feature under the "Formulas" tab to help find and fix errors.
3. Review the data source to ensure all references are correct and there are no blank cells or incorrect data.

By regularly checking for errors, you can ensure the accuracy of your Pivot Table calculations.

49. How Does The Pemdas Rule Apply To Formulas In Excel?

PEMDAS is a mathematical rule used to determine the order of operations in an expression. It stands for Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. In Excel, it applies to formulas in the following way:

1. Parentheses: Excel evaluates expressions inside parentheses first.

2. Exponents: Next, it evaluates any exponents.

3. Multiplication and Division: Then, Excel performs multiplication and division from left to right.

4. Addition and Subtraction: Finally, it evaluates addition and subtraction, again from left to right.

For example, in the formula =5 + 2 * (10 - 3)^2, Excel first calculates (10 - 3), then squares it, multiplies by 2, and finally adds 5.

50. How Can You Modify The Value Field Settings In Pivot Tables To Show Different Results Other Than Sum?

In a Pivot Table, you can modify the value field settings to display results other than the default Sum. To do this:

1. Right-click on the value field in the Pivot Table.
2. Select "Summarize Values By."
3. Choose from options like Count, Average, Max, Min, Product, or Standard Deviation.

Additionally, advanced techniques like using custom calculations or DAX (Data Analysis Expressions) allow for more complex operations, such as calculating running totals, cumulative averages, or custom formulas tailored to your analysis needs. This makes Pivot Tables even more powerful for detailed data insights.
