Excel labels columns using letters instead of standard numbers. The first 26 columns are A through Z, which correspond to 1 through 26. After that, Excel continues with combinations such as AA, AB, and AC.
In other words, Excel column labels work like a letter-based numbering system. This tool calculates the numeric index of any Excel column name automatically.
