I'm going to start with the standard functions for Google Sheets that will remove your text strings and characters from cells. In this tutorial, you have learned how to use the SQL TRIM function to remove unwanted characters from a string.Formulas for Google Sheets to remove text from cells Phone_number = TRIM(phone_number) Code language: SQL (Structured Query Language) ( sql ) If you need to clean up data, you can use the UPDATE statement with the TRIM function to remove all unwanted characters from the database especially the spaces.įor example, the following statement removes all leading and trailing spaces in the first_name, last_name, email, and phone_number columns of the employees table. ![]() If you are not, the data not clean that results in incorrect matching using the WHERE clause. Before insert or update the database, you need to validate and remove the spaces. Sometimes, when users submit the form that contains input fields such as first name, last name, email, phone, etc., the data may contain leading and/or trailing spaces. SELECT TRIM( FROM Code language: SQL (Structured Query Language) ( sql ) trim The following statement removes both leading and trailing of the string. ![]() ![]() SELECT TRIM( LEADING '0' FROM '00001900') Code language: SQL (Structured Query Language) ( sql ) trim The following statement removes leading zero of a string because the trim_character is ‘0’. Of course, the length of the result string must be three. The following statement removes both leading and trailing spaces of the string. SELECT LENGTH( TRIM(TRAILING FROM ' SQL ')) The length of the string must be five because the TRIM function removes one space at the end of the string. The following statement uses the TRIM function with the TRAILING option removes all trailing blank spaces of the string. SELECT LENGTH( TRIM( LEADING FROM ' SQL ')) The length of the result string must be four because the TRIM function removes two spaces at the beginning of the string. You can test it by using the LENGTH function. The following statement uses the TRIM function with the LEADING option to remove all leading spaces of the string. (1 row) Code language: SQL (Structured Query Language) ( sql ) SELECT LENGTH( ' SQL ') Code language: SQL (Structured Query Language) ( sql ) length Suppose we have a string that contains two spaces at the beginning and one space at the end of the string ( ' SQL '). The TRIM function returns NULL if either trim_character or source string is NULL.
