Looping over all columns manipulating each - KNIME Forum (91438)

Looping over all columns and manipulation of each

The workflow iterates over all numeric columns and negates the values in the column. The loop takes one column at a time, renames the column name to ANONYMOUS_COLUMN in the first rename node, changes the value in the math formula nodes and reverts the name to the original column name.
