Edit Data Guide

The Edit Data Guide dialog box enables users to specify how data guide should be generated for a selected JSON type column. The dialog box has two tabs:

• Structure: Displays the JSON data structure for the selected column

• Data: Displays the content of the imported or generated Data Guide table

You can perform the following tasks:

• Generate Data Guide: You can generate a new data guide table whenever the node is run or rerun. To generate a data guide, select any of the following options from the Data Guide Generation drop-down list:

  • Default: If the option Generate Data Guide if necessary in the JSON Settings dialog box is selected, then the data guide table is generated whenever the node is run or rerun. Otherwise, no data guide is generated.

  • On: Select this option to generate a new data guide table whenever the node is run or rerun.

  • Off: Select this option to not generate a new data guide table whenever the node is run or rerun.

  • Import from Workflow: Select this option to import a data guide from an existing JSON type column defined in a Data Source node or Create Table node within the same workflow or from a different workflow using the Select Data Guide dialog box.

  • Import from file: Select this option to import a data guide from a CSV file. The process validates the data guide, that is, it verifies the correctness of the column header, JSON path format, JSON types, and so on during an import operation.

• Remove Data Guide: To delete the current Data Guide table, click .

• Export Data Guide: Select this option to export the current data guide table to a CSV file. If you find the generated data guide does not fully represent the underlying JSON data, then you have the option to export the data guide and add any missing JSON paths. You can then import the data guide back to replace the generated one.
