Yes, there is a way to find the position of the 2nd, 3rd, or nth occurrence of a character in a string in Excel.

You can use a combination of the FIND and SUBSTITUTE functions to achieve this.

Here's an example of how to find the position of the 2nd occurrence of the letter "e" in the string "Excel is awesome":

1. Start by using the FIND function to find the position of the first occurrence of "e" in the string. The formula would be:
   Formula:

   =FIND("e", "Excel is awesome") 

2. Next, use the SUBSTITUTE function to replace the first occurrence of "e" with a different character that is not in the string. For example, you could use the "|" character. The formula would be:
   Formula:

   =SUBSTITUTE("Excel is awesome", "e", "|", 1) 

3. Now that the first occurrence of "e" has been replaced, you can use the FIND function again to find the position of the second occurrence of "e". The formula would be:
   Formula:

   =FIND("e", SUBSTITUTE("Excel is awesome", "e", "|", 1)) 

4. Finally, subtract the length of the string up to the first occurrence of "e" (which you found in step 1) from the position of the second occurrence of "e" (which you found in step 3) to get the position of the second occurrence of "e". The formula would be:
   Formula:

   =FIND("e", SUBSTITUTE("Excel is awesome", "e", "|", 1)) - FIND("e", "Excel is awesome") 


This will return the position of the second occurrence of "e" in the string "Excel is awesome". You can modify the formula to find the position of the 3rd, 4th, or nth occurrence by adjusting the number in the SUBSTITUTE function to replace the appropriate occurrence of the character.
