Data Table In Excel : One Variable and Two Variable (In Easy Steps )

Data Table is a tool present in Microsoft Excel as one of the three What-If Analysis tools namely Scenario Manager, Goal Seek, and Data Table. It is a tool, that allows one to try out various input values for the formulas present in their sheet and see how changes in those values affect the output in the cells. To apply a data table tool anywhere in the Excel sheet, there must be a table and the formula whose values will be replaced by the row and column values must be kept in the top-left corner or the top-right corner of the table according to the variables used to replace the formula values. In this article, we will learn about data tables in Excel.

What is a Data Table in Excel

Excel data tables shine brightest when dealing with intricate formulas that rely on multiple variables. With the ability to manipulate diverse inputs and witness the ripple effect on formula outcomes, data tables provide an invaluable avenue for comparative analysis and insightful decision-making.

Currently, two variations of data tables grace Excel’s repertoire: the one-variable data table and the two-variable data table. While the two-variable data table is restricted to a maximum of two distinct input cells, its potential for exploration remains boundless, allowing you to traverse a wide spectrum of variable values and delve deep into the heart of data-driven discovery.

What is Use of Data Tables in Excel

Data tables can be used to replace the values of a formula present in the sheet with the values present in either the column or row of any table. With data tables, one can replace at most two values in the formula present in the sheet.

For example, we can see in the below figures, there is an Excel sheet that is used to calculate simple interest over a given amount for a given number of years for a given rate of interest per annum. With the help of a Data Table, we can calculate the interest for the same amount with different numbers of years and with different rates of interest. We can also, calculate the interest for different amounts, for different numbers of years for a fixed rate of interest very easily.

How to Create Data Table in Excel with Different Types

One Variable Data Table

In a one-variable data table, only one of the formula values is replaced with the row or column values of a table of data. 

For Example:

Let us say we want to find interest on the principal amount of the loan for 4 years for various interest rates, we can do this by placing the interest rates in either the row or column of a table and then using the data table we can replace the interest rate values with the row or column values, in the example below, we have placed the variables in the column of a table. The cell containing the formula is placed in the top right corner which contains empty cells for storing the calculated interest but do remember to keep the cells containing the other values in the formula linked with the cell containing the formula. The process is done as shown below:

How to Create a One Variable Data Table in Excel

Embrak on a journey of formula exploration with the potent tool of a one-varible data table in Excel. This dynamic feature serves as a portal to a realm of testing and analysis, enabling you to dissect the intricate relationship between a single input cell and its profound influence on a connected formula’s outcome.

The essence of a one-varible data tables lies in its ability to scrutinize a range of values attributed to a solitary input cells, unveiling the mesmerizing interplay between these variations and the resulting formula outputs. As you traverse this domain of experimentation, a vivid tapestry of insights emerges, guiding your decison-making process with newfound clarity.

Step 1: Top Right Cell Contains Formulas

The top right cell is the cell that contains the formula for simple interest and it is linked with the cells containing the value of principal amount, number of years, and interest rate. The formula is =B3*B4*B5. 

Step 2: Select the Table With All Inputs and Select Data Table

To use the data table tool, we need to select the table with all the inputs and the cell containing the formula. Go to what-if analysis, and select Data Table. A Data-Table dialogue box appears. Add, Column Input cell value as $B$5. Click Ok. 

Step 3: Follow the Above Step for Row

If the variable interest rates were kept in the rows then we would have done the same thing but instead of putting B5 in the column input, we would have placed it in the row input. Below, are shown the values of Interest in the excel sheet. 

Two-Variable Data Table

In a two-variable data table, two of the formula values are replaced with the row and column values of a table of data. Two is the maximum number of values that can be used as variables in a data table since the values are replaced with row and column values which is a 2-D structure.

For Example:

Let us say we want to find interest on the principal amount of the loan for various numbers of years along with various interest rates, we can do this by placing the interest rates in either the row or column of a table and placing the numbers of years in the other row or column of the table mentioned before, then using the data table we can replace the interest rate values with the row or column values and numbers of years with the other row or column, in the example below we have placed the interest rate variables in the column and numbers of years variable in the row of a table. The cell containing the formula is placed in the top left corner. Do remember to keep the cells containing the principal amount in the formula linked with the cell containing the formula. The process is done as shown below:

How to Make a Two Variable Data Table in Excel

A two-variable data table is your window into understanding the dynamic relationship between two different set of inputs and their collaborative effect on a formula’s output. It’s like watching a carefully choreographed performance, where each change in these inputs pairs results in a unique transformation of the final result.

Thes steps to create a two-variable data table in Excel are basically the same as in the above example, except that you enter two ranges of possible input values, one in a row and another in a column.

Step 1: Top Left Cell Contains Formulas

The top left cell is the cell that contains the formula for simple interest and it is linked with the cell containing the value of the principal amount. The formula is =B3*B4*B5. 

Step 2: Select Data Table and Fill Details Followed by Pressing OK

To use the data table tool, we need to select the table with all the inputs and the cell containing the formula. Go to what-if analysis, and select Data Table. A Data-Table dialogue box appears. Add, Column Input cell value as $B$5, and Row input cell value as $B$4. Click Ok. 

Step 3: Interchange Values

We can interchange the values in the rows and columns but accordingly we have to change the row and column input values in the data table. Below, are shown the values of interest for the various number of years. 

Data Table to Compare Multiple Results

Imagine having the ability to gather insights from not just one, but multiple formuals all in one go. With your data table as the canvas, you can now embark on a journey of formulaic exploration like never before.

Expanding the horizons of your data table is a simple as it sounds. If your data table is organized vertically in columns, you can add new formuals to the right of teh existing ones. On the other hand, if your data table is organized horizontally in rows, the additional formuals find their place just below the first one.

For the “multi-formula” data table to work correctly, all the formulas should refer to the same input cell.

Data table in Excel : Things to Remember
