Hello @venkat4u,

You can use the following sintax to initialize a 2d array: **{({“1”,“2”}),({“3”,“4”})}**.  
Here is an example 🙂  
[2dArray.xaml](https://global.discourse-cdn.com/uipath/original/3X/8/b/8b1379b95a47dbe4db8949ab81111be73f85adf6.xaml) (4.6 KB)

Best Regards,  
Susana

How do I get the variable type String - all I can see is String (that is supposed to be square brackets - could not work out how to type that in).
