CSV and TSV files as tables
Enable the Database Tools and SQL plugin
This functionality relies on the Database Tools and SQL plugin, which is bundled and enabled in CLion by default. If the relevant features aren't available, make sure that you didn't disable the plugin.
Press Ctrl+Alt+S to open the IDE settings and then select .
Open the Installed tab, find the Database Tools and SQL plugin, and select the checkbox next to the plugin name.
CLion lets you edit files with delimiter-separated values (CSV, TSV, and other delimiter-separated formats) as tables.
For these files, a Data tab is available in the lower left corner of text editor. In the Data tab, you can edit the data in data editor. For full information about data editor, refer to Data Editor Dialog.
The data editor is available if the following conditions are satisfied:
The bundled Database Tools and SQL plugin is enabled. For more information, refer to Plugins.
The filename extension is associated with the text file type. For more information, refer to File types.
To switch between text and table views, click the Text and Data tabs in the lower left corner of the editor.
Open DSV file in the table view
Right-click inside a delimited text file and then click Edit as Table. Alternatively, you can click the Edit as Table icon in the editor.
In the Configure CSV Format for <file_name> dialog that opens, specify format settings and click OK.
The dialog has three predefined formats (CSV, TSV, and Pipe-separated) and lets you create a custom format. For example, you may require comma-separated values with semicolons as row separators.
Once you confirm the format settings, the Data tab will present data in a table format correspondingly. If you want to use different format settings, repeat the previous procedure and open the data editor again.
For more information about the Configure CSV Format for <file_name> dialog, refer to the reference.
Sort data
Click the column header to toggle between sorting directions: ascending, descending, and initial unsorted state.
The column sorting is not stacked by default. It means that if you click a column name to sort data by, the sorting based on other columns will be cleared. If you prefer to use the stacked sorting, click a column name while pressing Alt.
State
Description
Indicates that the data is not sorted in this column. The initial state of the sorting marker.
The data is sorted in the ascending order.
The data is sorted in the descending order.
The number to the right of the marker (1 on the picture) is the sorting level. You can sort by more than one column. In such cases, different columns will have different sorting levels.
Hide columns
Right-click the column header and then click Hide Column.
To see the list of all columns, right-click any column header and then click Columns List. Names of hidden columns are shown struck through. To toggle between hidden and shown state of a column, select it in the list and press Space.

Extract data
If you need to use the data from the table elsewhere, CLion provides several possibilities to copy or save it.
CLion uses data extractors to export data in various formats to a file or the clipboard. Each time you export or copy data, the copied data format is defined by the selected data extractor.
For more information about data extractors, refer to the corresponding page.
Export data to file or clipboard
To export full data to a file, open a table and click the Export Data icon (
