Devart Excel Add-in for Oracle allows you to connect Excel to Oracle databases, retrieve and load live Oracle data to Excel, and then modify these data and save changes back to Oracle. Here is how you can connect Excel to Oracle and load Oracle data to Excel in few simple steps.

To start linking Excel to Oracle, on the ribbon, click the DEVART tab and then click the Get Data button. This will display the Import Data wizard, where you need to create Excel Oracle connection and configure query for getting data from Oracle to Excel:

1. Specify Connection Parameters
2. Select whether to Store Connection in Excel Workbook
3. Configure Query to Get Data

Editing Live Oracle Data

After the data is loaded from Oracle to Excel spreadsheet, you can work with these data like with usual Excel worksheet. You can instantly refresh data from Oracle by clicking Refresh on the Devart tab of the ribbon, and thus, always have fresh live data from Oracle in your workbook.

If you want to edit Oracle data in Excel and save changes made in Excel to Oracle database, you need to click Edit Mode on the Devart tab of the ribbon first. Otherwise, the changes you make cannot be saved to Oracle.

After you start the Edit mode, you can edit the data as you usually do it in excel - delete rows, modify their cell values. Columns that cannot be edited in Oracle, will have Italic font, and you cannot edit values in these columns. To add a new row, enter the required values to the last row of the table that is highlighted with green.

To apply the changes to actual data in the database, click the Commit button. Or click Rollback to rollback all the changes. Please note that the changes are not saved to the database till you click Commit, even if you save the workbook.
