Now, extract a substring (user name) available before the character from it, use the following formula: Char parameter takes the character before which a substring will extract.textString will contain the string from which the substring will be extracted.=LEFT(textString, SEARCH("char", textString) -1) The following is the syntax to extract the substring before a specific character. So, the result returned by the SEARCH() function is an integer number that is used in place of number of characters. They are used together, where SEARCH() is used inside the LEFT() function as the second parameter. It requires two functions: LEFT() and SEARCH(). This method will help you to achieve this type of result. For example, javatpoint2011 (user name) from (email id). This may usually be required while extracting the user name from the email id. Sometimes we need a string to be extracted before a specific character. Extract a substring before a specific character See the substring extracted from the string Hello world! that was initially containing spaces in beginning and end.įor detailed learning of TRIM() function, click here (()%20function,-Extra%20space%20in&text=TRIM()%20function%20is%20a,between%20space%3B%20it%20removes%20all.) and follow our complete tutorial with example explanation. We have a string ( Hello World!) in B4 cell on which we will apply the TRIM() formula to remove the leading and trailing spaces and get the extracted substring.įor this, write the formula as showing below: The user needs to provide the string cell reference (or string itself in double-quotes) and the number of characters to be extracted from it. The Left() function extracts the characters from the left side of the string. These methods, we will discuss in this chapter with detailed explanation. Extract a substring after a specific character.Extract a substring before a specific character.Extract substring by removing leading and trailing spaces - TRIM().You will find these functions very simple and easy to use. Then, you can use them accordingly with your data. In this chapter, we will discuss the methods to find the substring with their examples. Some of these functions are used directly and some are used inside another function to get the targeted substring. They help the users to extract the substrings in different ways. But it offers several others functions, such as LEFT, RIGHT, MID, TRIM, LEN, FIND, SUBSTITUTE, REPT, and MAX. Excel does not provide any direct function for this. A substring is a string that is extracted from a complete string. It always pays to pay attention to these little edge cases.There is no specific formula in Excel to extract a substring from the other string. otherwise, default to the empty string (or some other value) if the substring does occur within the string, set the values accordinglyĪfter = str.substring(position + substr.length()) To make the first answer more efficient - as it is my preferred answer - then, we would need to remember the position of the substring: final int position = str.indexOf(substr) As such, I would much rather the first solution, since it works irrespective of the composition of the original substring. Also, since split will interpret its input as a regular expression we have to be wary of invalid regular expression syntax. Which ensures that the returned array has at most two elements. To that end, if we only want the first one to be recognized, it would be safer to call split with a limit: String parts = str.split(substr, 2) It is noteworthy that the second answer not work if we have more than one occurrence of the substring. String after = str.substring(str.indexOf(substr) + substr.length()) String before = str.substring(0, str.indexOf(substr)) You can do this: String str = "123dance456"
