Export multiple databases to one Excel file

Hello,
I am looking for a script that allows me to export multiple databases (4 standard databases) to one Excel file in multiple tabs, such as: 
- IDEA Database A = Excel tab A
- IDEA Database B = Excel tab B
I found a script on this forum where you can indicate which IDEA databases should be exported to one Excel file, because in my case there are four identical IDEA databases at all times, I would like to leave out this window and export the 4 databases concerned to one Excel file with multiple tabs by default. 
I hope someone can help me with this, thank you in advance.
