DataHub reads all data from a CSV file that is stored in the memory, and populate a treeview in DataHub Explorer. Whenever a CSV Data Source reloads new data from a CSV file into the DataHub's memory, that particular information will appear in the treeview.

Now if you change or update some data in the CSV Data Source through the treeview, DataHub will not save that piece of information automatically into the CSV file. You need to save it manually through the Save context menu in order to save those updates on the CSV Data Source into the CSV file.

For example, we have deleted nodes Category Types and Creating New Teamwork Projects from the CSV Data Source through the treeview. But, they are still present in the corresponding CSV file because DataHub does not save updates on the CSV Data Source to the CSV file automatically, and vice versa, see figure below.

Updated Data in CSV Data Source

To save updates on the CSV Data Source into the CSV file


  • Right-click the CSV Data Source in the treeview in DataHub Explorer and click Save , see first figure below. DataHub will update the CSV file with new data from the CSV Data Source, see second figure below.
