If you're working in Microsoft Excel, you can use formulas to generate alphabet sequences starting from a specific cell. Let's explore how you can achieve this using Excel formulas.

Using the ROW() and CHAR() Functions:

In cell E1, you can enter the following formula:

                =CHAR(MOD(ROW()-1,26)+65) & ROUNDUP((ROW()-1)/26,0)
            

This formula uses the CHAR() function to convert a number into a character based on its ASCII code. The ROW() function returns the row number of the cell, and the MOD() function calculates the remainder when dividing by 26, ensuring that the sequence repeats after 'Z'. The ROUNDUP() function determines the sequence number.

Drag this formula down to fill the cells in column E, and it will generate the alphabet sequence starting from E1.

Extending the Sequence:

If you want to extend the sequence to more rows, simply drag the formula further down. The formula will automatically adjust to generate the sequence continuously.

This method allows you to generate alphabet sequences without any programming, using Excel's built-in functions.
