Concatenate two or more fields in Tableau Use the plus sign (+) operator to combine two string fields: Go to Analysis > Create Calculated Field . Name the calculated field and enter the following formula: [String1] + [String2] + [String3].... Click OK . Additional Information Using a plus sign (+) combines two string fields together ("abc"+ "def" = "abcdef"). If a space is needed between the two fields, modify the above formula "abc" + " " + "def" = "abc def" Any required punctuation (e.g. comma) may be added into the formula as needed.
