Conversion from integer to Excel Column (Base 26) A-Z/AA/AAA etc

@rahatadi

Hi, basically I need a workflow that:

  1. Converts a number to Base 26 notation e.g. converts E to 5, 27 to AA, 52 to AZ, 53 to BA and so on.
  2. Does the inverse i.e. parses BA28 to column number 53, row 28… E30 to column 5, row 30 etc.

It should work with any length of column label e.g. A-Z, AA-ZZ, AAA-ZZZ and so on. So I can just shift right one cell and it switches from Z10 to AA10, or shift left one cell from BA11 to AZ11 etc.
