US Patent 11250032 Data preparation user interface with conditional remapping of data values

A method prepares data for subsequent analysis. The method displays a user interface that includes a plurality of panes, including a data flow pane and a data pane. The data flow pane includes a flow diagram having a plurality of nodes, each node specifying a respective primary operation or specifying a plurality of secondary operations to clean a respective data set. The data pane includes a plurality of data values in rows and columns. The data values correspond to a selected node in the data flow pane. A first user input selects a first data value in a first column and receives a second user input to edit a second data value in a second column according to one or more predefined conditions. The method then highlights the second column. When the predefined conditions are met, the method changes the second data value to a replacement data value.
