Posted on 7 Jan 2022 11:49:49 by 1,278 Super User 2024 Season 1

Hello, 

 

I have the follwing array which I get from a SQL import, filtered and is now a single object array. It is stored like this in a compose action: 

[
{
"ShipmentNumber": "1005",
"Analysis1": 23,
"Analysis2": 135655,
"Analysis3": null,
"Analysis4": 0,
"Analysis5": "10",
"Analysis6": "7"
}
]

 

I would like to remove the brackets [ ] from the start and end of the array, since these are creating some issues and using the values further. I would like to have the array in the exact same format. 

 

I tried the follwing: 

 

replace(replace(outputs('withBrackets'), '["', ''), '"]', '')

 

But I get the follwing errormsg:

Any help would be really appriciated.

    I am having the same issue. Need a way to remove the square brackets without it adding backslashes. I've tried this into an array variable, which works but it cuts the dataset to a single array (from multiple): array(json(replace(replace(string(outputs('Merged_Data')),'[',''),']',''))). I think I need a way to convert it back to Json without cutting the dataset.

    Re: Remove [ ] Brackets from single object array

    Hello,

    I am running into the same issue. 

    I am trying to avoid using substring as it converts the array to a string and adds additional \ which I am unable to remove when using an append-to-string action. 

    Is there a way to:

    A) remove the array [] without converting to string, OR

    B) remove \ from a string? (I have tried the following:

                      replace(output('actionname'),'\','')

                      replace(output('actionname'),'\\','')

                      replace(output('actionname'),'\"','"') 

    but none of the worked.

    Thanks in advance.

    Since its an array you need to convert to string()

     

    Try the following

     

    replace(replace(string(outputs('Compose')),'[',''),']','')
