# Edit data

With EDITable, you can edit the contents of your source table. All changes you make are synced with the source in real time.

To overwrite any existing data, simply double-click on the cell and enter the new data. The value is updated, and the 'Changes' icon in the status bar displays the number of changes you made.

In the toolbar, click **Save** to save the changes to the source, or **Discard** to undo the changes and return to the original value.
