=RIGHT(A19,LEN(A19)-FIND(",",A19,1))

As an AI language model, I am not sure what is the context of this formula. However, I can provide a general explanation of what this formula does.

- RIGHT: This is an Excel function that returns a specified number of characters from the right side of a text string.
- A19: This is the cell reference or the text string that contains the data to be manipulated.
- LEN: This is an Excel function that returns the length of a text string.
- FIND: This is an Excel function that searches for a specific character or text within a text string and returns its position.
- ",": This is the character that the FIND function is searching for within the text string.
- 1: This is the starting position of the search. In this case, it starts searching from the first character of the text string.

Therefore, this formula extracts the text to the right of the first comma (",") in cell A19. The LEN function calculates the length of the entire text string in A19, and the FIND function finds the position of the first comma. The RIGHT function then returns the text to the right of the comma.
