There are a few ways to pull initial letters from a string in Excel. One way is to use the LEFT function. The LEFT function takes two arguments: the text string and the number of characters you want to extract from the left side of the string. For example, if you have a list of names in column A and you want to pull the first letter of each name into column B, you would use the following formula:

=LEFT(A1,1)

You can then drag this formula down column B to apply it to all cells in that column. Another way to pull initial letters from a string is to use the MID function. The MID function takes three arguments: the text string, the starting position, and the number of characters you want to extract. For example, if you have a list of names in column A and you want to pull the first letter of each name into column B, you would use the following formula:

=MID(A1,1,1)

You can then drag this formula down column B to apply it to all cells in that column.
