You should not use regex for parsing JSON. Instead parse JSON through inbuilt functions like parse in case you are using Javascript or different libraries like GSON in case you are using JAVA.

Still, if there is any special requirement to use Regex here, you can use below:

1) For text:

.*?text"\s?:\s?"([\w\s]+)

Output : 

Group 1 - 'hello world'

2) For name 

.*?name"\s?:\s?"([\w\s]+)

Output: 

Group 1 - java

-- EDIT --

If you want both text and name in one regex, you can use below one, provided text always come before name:

.*?text"\s?:\s?"([\w\s]+).*?name"\s?:\s?"([\w\s]+)

Output:

Group 1.    46-57   `hello world`
Group 2.    68-72   `java`

You can use this regex : 

"name"\s?+:\s?+"?([\w+#\s]+)"?

to extract its value here name for example

if you want other key for example text use text instead of name

"text"\s?+:\s?+"?([\w+#\s]+)"?

you'll find the value of the key in the first group See here https://regex101.com/r/1ZSUph/1

var data = '{"data":"1233","image":"dsfsdfsdfds", "text":"hello world", "name": "java"}';

var parsedData = JSON.parse(data);

var text = parsedData.text;
var name = parsedData.name;
