When I use the list viewer to get my scanned items, there is always many empty slots between each item. How do I solve this?

You can use the `replace all` Text block to replace [newline] with an empty string (“”):

If you need help with that, post a screenshot of the blocks you’re using to get scanned items.

I did that, but then, say the device name was ‘esp32’, the layout will be like the following:

e  
s  
p  
3  
2

Solved. I used the following code:

Do you mind sharing the solution so other people who read this topic later will know?
