This video covers a variety of DAX functions for working with text. You'll learn how to join text together using the Concatenate and CombineValues functions and the concatenation operator. You'll see how to use the Format function to apply standard and custom formats to values. You'll learn how to extract text from the left, right and middle of a string, as well as how to locate the characters you want to extract using the Find or Search functions. You'll find out how to remove extra spaces from a string and how to calculate the length of a string. Finally, you'll see how to use the Replace or Substitute functions to replace one piece of text with another.
