Regex for Parsing JSON

Question

I have a column of data I'm reading in Tableau directly from Redshift. This column contains a JSON object. It looks like this:

{"Age": 58, "City": "Wisconsin Rapids", "Race": "Other", "State": "Wisconsin", "Gender": "Female", "Country": "United States"}

I wish to extract this data by generating a column with a calculated field for each data point of interest using Tableau's REGEXP_EXTRACT function. I.e. an Age column, a City column etc.

How do I write a line of regular expressions to get the value of 58 for Age, Wisoncsin Rapids for City, etc.

Thanks!

You can use this regex :

"Age"\s?+:\s?+"?([[:alnum:]\s]+)"? 

to extract its value here Age for example

if you want other key for example State use State instead of Age

"State"\s?+:\s?+"?([[:alnum:]\s]+)"?

you'll find the value of the key in the first group See here https://regex101.com/r/KA7PSl/2
