Interpolation is a powerful tool in Excel, allowing users to fill in missing data points in an accurate, reliable manner. It can be used to quickly develop estimates from existing data, making it an invaluable tool for any Excel user. In this article, we will explore the various interpolation functions available in Excel, including linear, exponential, and polynomial interpolation, as well as some of the more advanced functions such as cubic splines and fixed interpolation. We will also discuss how to use these functions to fill in missing data points and what they can do for you.
Interpolation is the process of estimating a value between two known points. It is frequently used to fill in missing data points, allowing users to quickly develop estimates from existing data. Excel offers several different interpolation functions, each of which can be used to fill in missing data points in a different way.
The most basic interpolation function available in Excel is linear interpolation, which is used to fill in missing data points in a straight line. Linear interpolation is the simplest and most common type of interpolation, as it is the easiest to calculate and is often the most accurate. However, it is not always the best choice for filling in missing data points, as it can be inaccurate when the data points are not evenly spaced.
Excel also offers two other interpolation functions, exponential and polynomial interpolation. Exponential interpolation is used to fill in missing data points along a curved line, while polynomial interpolation is used to fill in missing data points along a curved line with more complex shapes. Both of these functions are more accurate than linear interpolation, but they can be more difficult to calculate.
In addition to these basic interpolation functions, Excel also offers several more advanced functions, such as cubic splines and fixed interpolation. Cubic splines interpolation is used to fill in missing data points along a smooth curve, while fixed interpolation is used to fill in missing data points along a fixed curve. Both of these functions are more accurate than linear, exponential, and polynomial interpolation, but they can be more difficult to calculate.
In summary, interpolation is a powerful tool in Excel, allowing users to quickly fill in missing data points in an accurate and reliable manner. Excel offers several different interpolation functions, each of which can be used to fill in missing data points in a different way. In this article, we have discussed how to use these functions to fill in missing data points and what they can do for you.
Interpolation is a mathematical process used to estimate values between two known points within a dataset. The “Interpolation” function in Excel is a powerful tool used to fill in missing data points by calculating values between known points in a dataset. It can also be used to calculate the missing values in a chart or graph.
To begin using the Interpolation function in Excel, the first step is to create a dataset of known data points. This can be done by inputting the known data points into a table or by plotting a graph. Once the data points are entered, the Interpolation function can be used to calculate the missing values.
To use the Interpolation function, open the function wizard in Excel by clicking on the “fx” icon in the formula bar. Next, choose the “Interpolation” function from the list of available functions. The function wizard will display a window that allows you to input the data points. The first two data points should be the known data points that you want to interpolate. The third data point should be the unknown value that you want to calculate.
After inputting the data points, click on the “Calculate” button to begin the interpolation process. The function will then calculate the estimated value based on the known data points. The result of the Interpolation function will be displayed in a cell in the worksheet.

The result of the Interpolation function will be displayed in a cell in the worksheet.
In conclusion, the Interpolation Function in Excel is a powerful tool that can help you quickly and accurately generate data points between two known data points. With its easy-to-use interface, it can be used by both experts and beginners alike. With the ability to calculate and interpolate data quickly and accurately, it can save you time and effort in creating accurate graphs and charts. Therefore, the Interpolation Function in Excel is an invaluable tool for data analysis.
