String

Contents[Hide]

The String transform manipulates string columns by applying string functions.

The following string functions are available, which are applied to the values in each row:

  • Trim - Removes whitespace characters at the beginning and end.
  • TrimStart - Removes whitespace characters at the beginning.
  • TrimEnd - Removes whitespace characters at the end.
  • Remove - Removes the specified number of characters starting at the specified position.
  • Replace - Replaces all instances of the specified text with the specified replacement text.
  • Substring - Keeps only the text at the specified position up to the specified length.
  • Left - Keeps only the specified number of characters starting from the left/beginning.
  • Right - Keeps only the specified number of characters starting from the right/end.
  • ToUpper - Replaces all lowercase letters with uppercase letters.
  • ToLower - Replaces all uppercase letters with lowercase letters.
