​What is the best approach to solve the removal of "No Data Available" string in a column?  For instance the column could be listing name, but instead of a blank or null there is a string "No Data Available"

    Hi Janet,
    you can create formula field and use the IF function.  Assume the column name is Name you can use the following formula:

    IF(Name="No Data Available","",Name)
    The above will create a new field.

    Hi Janet,

    In Data Prep Studio, you can right click on the column and use the 'Replace->Using Find and Replace' option. This will act on the original column or you can select the 'create new column' option, if you prefer.

    Regards,
    Steve.
