Mid("Hello", 1, 3)
"ell"
Trim(input)

RegexMatch("123", "\d{3}")

RegexReplace(input, pattern, replacement)
Performs a Regular Expression replace on the input string, returning the result.

Split(input, delimiter)
Divides the input string into substrings separated by the delimiter, returning a new table variable with a single value column containing the sub-strings. Note that the delimiter argument must be exactly one character long.
Split("2,89,16", ",")
<a table variable with one "value" column, containing three rows: value = 2, value = 89 and value = 16>
IsNull(input, replacement)
Replaces empty input values with the specified replacement value. If the input value is not empty will the value not be replaced.
IsNull("", 0)
0
DecodeText(input, encoding)
Decodes text encoded as binary data (from a BLOB database column or a File Gallery interaction item). The second argument specifies the encoding from which to decode. Valid values for this argument can be found in the "encodings" system variable, which is available in all workflows.
DecodeText(myFile.data, encodings.Windows1252)
<contents of myFile.data, decoded using the Windows 1252 Character Set>
