How Excel Column Letters Work
Excel columns use letters instead of ordinary numeric labels. 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.
This tool converts a numeric Excel column index into the letter-based column label that Excel uses automatically.
