@Left (Formula Language)

Searches a string from left to right and returns the leftmost characters of the string.


@Left( stringToSearch ; numberOfChars ) @Left( stringToSearch ; subString )



Text or text list. The string where you want to find the leftmost characters.


Number. The number of characters to return. If the number is 2, the first two characters of the string are returned; if the number is 5, the first five characters are returned, and so on. If the number is negative, the entire string is returned.


Text. A substring of stringToSearch. @Left returns the characters to the left of subString. It finds subString by searching stringToSearch from left to right.

Return value


Text or text list. The leftmost characters in stringToSearch. The number of characters returned is determined by either numberOfChars or subString. @Left returns "" if subString is not found in stringToSearch.


If the first parameter is a list, the function operates on each element of the list, and the return value is a list with the same number of elements.
