How to convert a column number into an excel column letter

Microsoft Excel has patterns such as A, B, C, AA, BB, CC, AD, AA, AAB, and AAZ. Column 1 is named as A, B as 2, and 27 as AA. Therefore, finding a column letter is easy and possible, given its corresponding column number is easy. To convert a column number to the letter in Excel, you can follow the following steps. It is important to note that this function only converts integers into their corresponding alphanumeric text character. The column or row headings on the physical worksheet are not changed in appearance.

Steps to convert a column Number

It is important to note that we deal with 26 characters from A-Z. Remember, we don't have zero among these characters since A represents 1 while Z represents 26. There are two ways to tackle this problem;

  1. Say you have the number 676, it is still possible to get its base representation.
  2. Divide and get a remainder of 26
  3. To get rid of zero, we get (25 26)to base 26; thus, its symbolic representation is YZ
