Monday custom ui based apps

(1). i want to display monday board items on my own custom ui created with react using monday custom apps documentation (or you can say custom boardview)?
Why does it results in json format not proper string format columns

Hello @sadaqatem!

I am not sure I follow the question.

What I see is that you are retrieving the information from a board using a query, and displaying the response from our server as received, in your view.

If you want this in a different format, you need to re format it on your end and then display it.
