If your dataset is linear, you can implement a linear interpolation method. The image below displays a set of formulas that you can use to perform linear interpolation on a linear set of data. Click the image for a detailed view How to Do Linear Interpolation for Non-linear Dataset in Excel?
In this article, I’ll discuss 7 methods on how to do linear interpolation using the functions in Excel along with the basics.
I don't actually need the Lookup function as the data will always change, so I would need to manually enter the data anyway. I tried using your formula but it doesn't give me the answer I need. PeterBartholomew1I also use Excel 365. I'll post an image of the table below: I hope...
Adding interpolation functions to the Excel using C# and Excel-DNA Download ACQ.zip - 3.2 MB Introduction Microsoft Excel has a lot of useful functionality and is widely used for data analysis. However it does not offer any built-in functions for data interpolation. This article describes how...
In Excel, I have a table of data giving fluid densities (rho) with temperatures (T) and pressures (P) as parameters. In other words, my table looks like this: DENSITY vs. T,P P1 T1 Rho1,1 T2 Rho1,2 T3 Rho1,3 P2 T1 Rho2,1 T2 Rho2,2 T3 Rho2,3 etc. My problem is that...

Ihem – thanks for sharing that compact matrix formula for one type of cubic spline. That may be the most impressive non-array formula that I’ve ever seen in Excel. I’d never thought of using the Internal Rate of Return function for fitting non-financial data. ...
An Interpolation function () is defined by a table or file containing the values of the function in discrete points. The interpolation data can be structured (defined on a grid) or unstructured (defined on a generic point cloud).The Analytic, Interpolation, and Piecewise functions can also be...
Scattered data interpolation is an essential technique used in environmental, geospatial and meteorological analysis. It enables the estimation of unknown values within a dataset at the domain by utilising known data points. The utilisation of this method is crucial to generate smooth and continuous ...
