_​Looping_​over_​all_​columns_​and_​manipulation_​of_​each 1

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.
