Remove rows from the top dataset with key values that are present in the lower dataset.






The output depends on the vertical (Y-axis) position of the inputs.

Select Top key column for the column you want to match in the top input dataset.

Select Bottom key column for the column you want to match in the bottom input dataset.



If there are 10k rows or less in both datasets, Easy Data Transform will try to guess sensible default values for Top key column and Bottom key column based on column header names and contents.

If the first input has a header, this will be used for the output.

All values are treated as text and comparisons are case and whitespace sensitive. You can use Case to change the case and Whitespace to remove whitespace before the subtract.

Does not remove duplicates. You can use Dedupe to do this.

You can use Concat Cols to join several columns together (e.g. 'first name' and 'last name' columns) to form a key column.

You can use Row Num to create a unique key column.
