I am using OPC-UA communication and i have string tag (Name of recipe). OPC Value shows "LocalizedText{text=CSX22, locale=null}" while i just need recipe name "CSX22".  
How can I get this fixed?

It's not a String datatype, it's an OPC UA LocalizedText type, which isn't something Ignition has a corresponding tag type or mapping for right now ☹

That's the Ignition Datatype it got set to, any unrecognized type gets set to a String and then its value becomes whatever the Java `Object::toString` representation is.

Its OPC UA datatype is LocalizedText.

If you can't change the datatype in the server then the only workaround I can think of for now is an expression tag or script that tries to extract the portion after `text=` and before `, locale=`.

Would this work for you?

 ![JSON get text](https://us1.discourse-cdn.com/inductiveautomation/original/3X/d/0/d0be2ad47389fb0dcd948d535443e9e1488c0235.png)

Expression: `jsonGet(jsonFormat({value}), "text")`

The value isn't exactly JSON, it includes the `LocalizedText` bit at the front that would need to be chopped off.

A couple of different expressions Both work, but both are also a bit of a kludge.:

```auto
jsonGet(jsonFormat(right({value},len({value})-13)), 'text')
split({value}, '=|,')[1,0]

```

I will say that if you have a lot of tags like this, it may be more efficient to roll this in to a UDT.
