IntelliJ IDEA 2024.2 Help

Data loaders

Enable the Database Tools and SQL plugin

This functionality relies on the Database Tools and SQL plugin, which is bundled and enabled in IntelliJ IDEA by default. If the relevant features are not available, make sure that you did not disable the plugin.

  1. Press Ctrl+Alt+S to open settings and then select Plugins.

  2. Open the Installed tab, find the Database Tools and SQL plugin, and select the checkbox next to the plugin name.

Data loaders are specialized scripts that allow you to import your tabular data files into a database. They also enable the visual representation of this data in the data editor. The view of such files in data editor is read only.

  • Data display in data editor. For example:

    1. Excel

      Contents of an Excel file displayed in data editor

    2. JSON

      Contents of a JSON file displayed in data editor

      To disable the Data tab with table view for JSON files, in the Advanced Settings page of settings  Ctrl+Alt+S, set the Open file as table if detected by scripted loader to Table-first formats.

    For more information about viewing data in data editor, refer to Data editor and viewer.

  • Data import from a file to a database

    Import tabular data file: Tabular data Source settings
    Import tabular data file: mapping settings

    For more information about importing data from a tabular data file to a database, refer to Import data from tabular data files.

To locate data loaders, open the Project tool window and navigate to Scratches and Consoles | Extensions | Database Tools and SQL | data | loaders.

You can also create and use your own scripted data loader that you can write on Groovy or JavaScript.
