Hi there! It sounds like you're trying to use the LEFT formula to extract the first character from multiple cells and combine them into one cell. Here's how you can do it:

1. First, you'll need to decide which cell you want to combine the first characters into. Let's say you want to combine them into cell D1.
2. In cell D1, you can use the following formula to extract the first character from cell A1:
   
   Formula:

   =LEFT(A1,1) 

   This formula tells Excel to take the first character from cell A1 and display it in cell D1.
3. To add the first character from cell B1 to the formula, you can use the ampersand (&) symbol to concatenate the formulas together:
   
   Formula:

   =LEFT(A1,1)&LEFT(B1,1) 

   This formula tells Excel to take the first character from cell A1 and combine it with the first character from cell B1, and display the result in cell D1.
4. To add the first character from cell C1 to the formula, you can continue to use the ampersand symbol to concatenate the formulas together:
   
   Formula:

   =LEFT(A1,1)&LEFT(B1,1)&LEFT(C1,1) 

   This formula tells Excel to take the first character from cell A1, combine it with the first character from cell B1, combine that result with the first character from cell C1, and display the final result in cell D1.
