Cell Replacer

Manipulator

Replaces cells in a column according to dictionary table (2nd input). The node has two inputs: The first input contains a target column whose values are to be replaced using the dictionary table (2nd input). From the dictionary table, choose one column (or the rowID column) that is used as lookup criterion. Any occurrence in the target column (1st input) that matches the lookup value is replaced by the corresponding value of the output column, which is another column in the dictionary table.

Missing values are treated as ordinary values, that is, they are valid as lookup and replacement value. If there are duplicates in the lookup column in the dictionary table, the last occurrence (bottom most row) defines the replacement pair.

If the input/lookup column is a collection type, each of the contained values in the collection is a search element.
