Remove a list of unwanted characters from a text string

This looks like a JSON string. Why not just use fromJson() to turn it into a dictionary and then use normal Appian functionality to display the values?

As Stefen Suggested, Use fromJson and then use index functionality to get the particular value based on the key.

After applying fromJson, I get this string: [Status:Active,updatedBy:,hasAccount:false]. Not sure what is it's data type as I did this in a forEach loop for every row of my grid column. 

Could you explain more of the normal Appian functions that you mentioned? 
What I could think of is: 

substitute(
stripwith(
"[Status:Active,updatedBy:,hasAccount:false]","[",
),
",",
char(10)
)

However stripWith only allow 1 character so I missed the "]", also I couldn't have the line break as expected. 

The result of my work is: 

"Status:Active updatedBy: hasAccount:false]"(Text), in which "]" has not yet been removed.

Thanks Deepak, the problem is that I need to apply the functions to all rows in a forEach loop, and not all of them have the same index for those characters to use index function :(

Hi mollyn126,

below snippet might helpful for your case

substitute(
stripwith(
tostring(
{
"Status": "Active",
"updatedBy": "lynn123",
"hasAccount": false
}
),
"[]"
),
",",
char(10)
)

fromJson does NOT return a string, but a dictionary containing key-value pairs. Appian does display it as a string.

You can then access the fields using dot-notation or index()/property(). Check the Appian documentation for how to do this.

I'm not sure why you are trying to convert the dictionary (fromJson()) to a string before iterating through it in a!forEach()?

What are you expecting for a final output, is this for display/rich text field, dictionary, etc?

a!localVariables(
  local!json: "[{""Status"":""Active"",""updatedBy"":""lynn123"",""hasAccount"":""false""}]",
  local!data: a!fromJson(local!json),
  
  a!forEach(
    items: local!data,
    expression: {
      /* process each item here */
      fv!item
    }
  )
)

Thanks AJ, the result came out just as my expectation :)
