The following example demonstrates functions that can be used to clean up strings. These functions include the following:

Source:

In the following (space) and (tab) indicate space keys and tabs, respectively. Carriage return and newline characters are also supported by whitespace functions.

Stringssource
String01this source(space)(space)
String02(tab)(tab)this source
String03(tab)(tab)this source(space)(space)
String04this source's?
String05Why, you @#$%^&*()!
String06this söurce
String07(space)this söurce
String08à mañana

Transform:

The following transforms generate new columns using each of the string cleanup functions:

derive type:single value: TRIM(source) as: 'trim_source'

derive type:single value: REMOVEWHITESPACE(source) as: 'removewhitespace_source'

derive type:single value: REMOVESYMBOLS(source) as: 'removesymbols_source'

Results:
