Download Excel File with Dummy Data
If you are working on a project that involves data analysis, you may need to use some dummy data to test your formulas, functions, charts, or reports. Dummy data is mock data generated at random as a substitute for live data in testing environments. In this article, you will learn what dummy data is, why it is useful, how to create it in Excel, and how to download it from a website.

What is Dummy Data and Why Use It?
Dummy data is fake data that mimics the characteristics of real data. For example, if you want to test a sales report, you may need some dummy data that contains product names, prices, quantities, dates, and customer details. You can use dummy data to fill in the gaps in your real data, or to create a completely new data set for testing purposes.
Definition and Examples of Dummy Data
According to Analyst Answers, dummy data is mock data generated at random as a substitute for live data in testing environments. It acts as a placeholder for live data, which testers only introduce once they are sure that the trial program does not have any negative impact on the underlying data.
For example, suppose you have the following dataset and you want to use age and marital status to predict income:
NameAgeMarital StatusIncome
Alice25Single$40,000
Bob32Married$60,000
Charlie28Divorced$50,000
David35Single$70,000
Eve30Married$55,000
To use marital status as a predictor variable in a regression model, you need to convert it into a dummy variable. Since it is currently a categorical variable that can take on three different values (Single, Married, or Divorced), you need to create k-1 = 3-1 = 2 dummy variables. To create this dummy variable, you can let Single be your baseline value since it occurs most often. Heres how you would convert marital status into dummy variables:
NameAgeMarital StatusIncomeMarried (Dummy)Divorced (Dummy)
Alice25Single$40,00000
Bob32Married$60,00010
Charlie28Divorced$50,00001
David35Single$70,00000
Eve30Married$55,00010
Now you have two dummy variables that represent the marital status of each person. You can use these dummy variables in your regression model along with age to predict income.
Benefits of Using Dummy Data for Testing
Using dummy data for testing has several advantages, such as:
It allows you to test your formulas, functions, charts, or reports without affecting the real data.
It helps you identify any errors or bugs in your code or logic before applying it to the real data.
It enables you to simulate different scenarios and outcomes by changing the values or characteristics of the dummy data.
It saves you time and resources by avoiding the need to collect or generate real data for testing purposes.

Using RANDBETWEEN Function
The RANDBETWEEN function returns a random integer between two specified values. You can use this function to create dummy data for numerical variables, such as prices, quantities, scores, etc. For example, if you want to create a dummy data set of 10 products with random prices between $10 and $100, you can use the following formula:
=RANDBETWEEN(10,100)
This formula will generate a random number between 10 and 100 in each cell where you enter it. You can copy and paste this formula to create as many rows or columns as you need. Here is an example of a dummy data set created using this formula:
Product NamePrice
Product A$54
Product B$23
Product C$87
Product D$45
Product E$76
Product F$12
Product G$34
Product H$98
Product I$67
Product J$41
Using VLOOKUP Function
The VLOOKUP function returns a value from a table based on a lookup value and a column index number. You can use this function to create dummy data for categorical variables, such as names, countries, colors, etc. For example, if you want to create a dummy data set of 10 customers with random names and countries, you can use the following steps:
Create a table with two columns: one for names and one for countries. You can use any source of names and countries that you like, such as online lists or databases. Here is an example of a table created using random names and countries from and :
NameCountry
Aaron SmithAustralia
Betty JonesBrazil
Charles LeeChina
Diana PerezMexico
Ethan BrownNew Zealand
Fiona TaylorCanada
Gregory WilsonGermany
Hannah MillerIndia
Ian ClarkJapan
Jennifer DavisUSA
Name this table as "Name_Country" by selecting the range of cells and typing the name in the Name Box on the left of the formula bar.
Create another table with two columns: one for customer ID and one for customer name. You can use any sequence of numbers for the customer ID, such as 1, 2, 3, etc. For the customer name, you can use the following formula:
=VLOOKUP(RANDBETWEEN(1,10),Name_Country,1,FALSE)
This formula will generate a random number between 1 and 10 and use it as a lookup value to find a matching name from the Name_Country table. The formula will return the name from the first column of the Name_Country table. You can copy and paste this formula to create as many rows as you need. Here is an example of a dummy data set created using this formula:
Customer IDCustomer Name
1Ethan Brown
2Betty Jones
3Aaron Smith
4Jennifer Davis
5Hannah Miller
6Diana Perez
7Ian Clark
8Fiona Taylor
9Charles Lee
10 Gregory Wilson
To create a dummy data set of 10 customers with random countries, you can use a similar formula, but change the column index number from 1 to 2. For example:
=VLOOKUP(RANDBETWEEN(1,10),Name_Country,2,FALSE)
This formula will return the country from the second column of the Name_Country table. Here is an example of a dummy data set created using this formula:
Customer IDCustomer Country
1 New Zealand
2 Brazil
3 Australia
4 USA
5 India
6 Mexico
7 Japan
8 Canada
9 China
10 Germany
Note that the RANDBETWEEN and VLOOKUP functions are volatile, meaning that they will recalculate every time you make a change in your workbook. If you want to keep your dummy data fixed, you can copy and paste it as values.

FAQs
Here are some frequently asked questions about dummy data and how to download Excel files with dummy data:
What are some sources of dummy data?
There are many online sources of dummy data that you can use for your projects, such as , , , , etc. You can also use your own real data and modify it to create dummy data.
How can I create dummy data for text variables, such as names, addresses, emails, etc.?
You can use the VLOOKUP function with a table of text values, or you can use the TEXT function with a formula that generates random characters. For example, if you want to create a dummy email address, you can use the following formula:
=TEXT(RANDBETWEEN(1,999),"000")&"@"&TEXT(RANDBETWEEN(1,999),"000")&".com"
This formula will generate a random email address in the format of xxx@yyy.com, where xxx and yyy are random numbers between 1 and 999.
How can I create dummy data for date variables, such as birthdays, anniversaries, etc.?
You can use the RANDBETWEEN function with a range of dates, or you can use the DATE function with a formula that generates random numbers for year, month, and day. For example, if you want to create a dummy birthday between January 1, 1980 and December 31, 2000, you can use the following formula:
=DATE(RANDBETWEEN(1980,2000),RANDBETWEEN(1,12),RANDBETWEEN(1,31))
This formula will generate a random date between January 1, 1980 and December 31, 2000.
How can I create dummy data for logical variables, such as yes/no, true/false, etc.?
You can use the RANDBETWEEN function with two values: 0 and 1. Then you can use an IF function to assign a logical value based on the result. For example, if you want to create a dummy yes/no variable, you can use the following formula:
=IF(RANDBETWEEN(0,1)=0,"No","Yes")
This formula will generate either "No" or "Yes" at random.
How can I download an Excel file from a website using Google Chrome or Firefox?
You can follow similar steps as using Internet Explorer, but instead of right-clicking on the link or icon of the Excel file and selecting Save Target As, you need to select Save Link As or Save Link As... depending on your browser. Then you can choose a location and a file name for your Excel file and click Save.
