Other add-ins, such as Java-based JINX, also lacks class libraries for structured data computations.

This means that Excel DNA is more suitable for professional programmers who use it as an interface, rather than for most of the data analysts who directly use it for desktop analysis. Actually, these languages have a high technological threshold. But configuring the Windows compilation environment is complex and difficult to learn. This type of programming languages requires users to maintain a compilation environment for compiling the algorithm, in case it is changed.

The extremely roundabout code isn’t suitable for handling complicated computations.īesides, C#, F#, and VB.net are compiled languages instead of interpreted languages. Hardcoding is needed even for the most basic calculations. Those languages lack class libraries for structured data computations. So why is that?īecause their capabilities exist only on paper. Surely this is not a good choice for display of strengths. But I noted that the sample programs in their websites are all about string output. In theory, languages like C#, F#, and VB.net are universal and all-powerful.

So the biggest advantage of Excel DNA is the high fluidity.Īs the name implies, the add-in can make full use of the facilities Windows DNA Architecture offers, such as development languages and tools, integration with Excel, interactive debugging, etc.
Since a compiled program is ready to execute and is closely integrated into Excel, the execution is smooth and fast. įinally, you configure the new add-in in Excel to be able to call MyFunction from a cell, as shown below: The following DnaSample.dna file configures the add-in’s name (“My name”) and the corresponding dynamic library Mylibrary.dll, which includes multiple user-defined functions. Then you configure the relationship between the user-defined function and the add-in. The code needs to be compiled as a dynamic library to be used in Excel. Public static string MyFunction(string name) Using ExcelDna.Integration namespace MyLibraryĮxcelFunction(Description="few people use this way!")] MyFunction is the name of the user-defined function. Below is an example written in C#, which is listed on the official website of Excel DNA. One of the earliest Excel add-ins, Excel DNA lets you create dynamic library functions for Excel using C#, F#, VB.net, etc.įirst, you need to write a user-defined function. Now I’ll investigate several common Excel add-ins and evaluate their computational capabilities. So it offers the add-in interface through which an external application can be connected to use their language or script to help Excel handle those computations. But it’s hard for it, alone, to accomplish complicated computations and certain special ones. Excel provides convenient methods, including easy to use functions and intuitive buttons and menus, for performing simple computations.
