How to Convert Numerical Column Numbers to Excel Column Names in C#?

C#in China convert the numerical column number to Excel list name

When processing the electronic meter and data analysis, converting the value to Excel list may be a useful task. This article will explore a C#method without using any automation or directly accessing Excel to convert the numerical column number (eg, 127) to its corresponding Excel name (eg, AA).

In order to achieve this conversion, we can use a simple algorithm that calculates the corresponding Excel name based on numerical iteration. The following is the step overview of the algorithm:

Initialize an empty string to store the name.
When the numerical column number is greater than 0:

2. Calculate the list of 26. This value represents the character index in the letters (A-Z).
   • The character index is converted to its corresponding characters ('a' character index) and adds it to the beginning of the column name.
   • Divide the column number with 26 and cut off the results (integer removal method).
Returns the name of the generated.
By achieving this algorithm, you can effectively convert any numerical column number into an effective Excel name. This technology is particularly useful for applications that require precisely operating electronic meter data (such as data extraction, analysis, and conversion).
