The Data Viewer

The Data Viewer is located in the middle on the upper half of the DataMapper screen. It displays the data source that is currently loaded in the DataMapper, specifically one record in that data. Where one record ends and the next starts is determined in the Data Source settings (see Record boundaries). One record may contain more than one unit: PDF or Text pages, XML nodes, CSV lines, etc.
When the Delimiter or Boundary options are set in the Settings pane, the Data Viewer reflects those changes.

Any modification of the source data by a Preprocessor takes place before the data is displayed in the Data Viewer (see Preprocessor step).

The Data Viewer lets you select data, extract them (Extracting data), and apply a condition where necessary.
How data can be selected depends on the type of source file (see Selecting data).

Once data is extracted, clicking on any Extract step on the Steps pane highlights any area from which it extracts data in the Data Viewer. You can click on the Preprocessor step to select all the steps in the extraction workflow and highlight all extracted data.
Clicking on other step types also has a visible effect in the Data Viewer:Clicking on a Repeat step shows where the loop takes place.Clicking on a Goto step shows where the cursor is moved.Clicking on a Condition step shows which data fulfil the condition.For more information about the different steps that can be added to a data mapping workflow, see Steps.
