Column Comparator

Compares the cell values of two selected columns row-wise. A number of different comparison methods are available: equal, not_equal, less, greater, less_equal, and greater_equal. A new column is appended holding either the left or right column value, a missing cell, or a user specified tag. The type of the appended column depends on the selected content: If a user defined tag is selected, the result column is of type string, in all other case the type is determined by the type of the selected columns.

Options

Column Left

Left column selected for comparison.

Column Right

Right column selected for comparison.

Operator

Comparison is done based on the selected operator option: equal, not_equal, less, greater, less_equal, or greater_equal

Replacement Method

Depending on the result of the selected operator, a certain value is set into the new column. Select one of the following options for the operator result 'true' and 'false': LEFT_VALUE - the value of the left column is set in the result column. RIGHT_VALUE - the value of the selected right column is used. MISSING - a missing cell is set in the result column. USER_DEFINED - the text entered in the corresponding 'Tag' field is set in the result column.

New Column

Name of the new appended column.
