C#/vb.net Excel Data breakdownSometimes we need to split the combined data saved in Excel cells into multiple columns (such as splitting the full name into two columns) to make it easier for us to process, remember, or save. To avoid duplication and a lot of manual input work, Excel provides us with a data-disaggregated function. The following diagram shows how to implement data disaggregation in Excel:This article will show you how to use C # and vb.net programming to achieve the functionality

However, please note that if your program requires cross-platform use, and the office COM component is not supported on the Target Platform (Why is there such a strange demand ?!), You may have some trouble. At this time, we can consider providing an alternative option in the program to disable the corresponding functions, so as to avoid the program mistakenly using the non-existing
