Hi all,

I'm stucked with this issue :

I have a json object like that :

{
 "key1": "", 
 "key2": "1/10", 
 "key3": "1/1,1/2,1/3,1/5", 
 "key4": "1/24", 
 "keyX": "1/1,1/2,1/3,1/5,1/4" 
 }

I want to return the key name for a given value.

For example, if I know a value (eg. 1/24), I want to get the key name (eg. key4).

the key name are not always the same, so I can't use the parse json tool.

Do you knows if it possible?
if yes, what is the best way to achieve that?

best regards,

You mentioned about an example 1/24. It seems to be unique.

But, for examples: 1/2 or 1/3 or few other values, they are associated with multiple keys. In these cases, are you expecting to have all the key names which matches the value?

With JSON parsing, i do not see a way to get the desired result. I am curious to see if anyone has ideas.

By using String manipulation actions, you can get to the desired result.

Created a sample to get the desired result:

Expression in Compose1:
trim(replace(replace(variables('varJsonString'),'{',''),'}',''))

Expression in Compose2:
split(outputs('Compose_1'),'",')

Expression in above Compose action:
concat(items('Apply_to_each'),'"')

Expressions in Condition:

1st Concat expression:
concat(variables('varInputValue'),',')

2nd Concat expression:
concat(variables('varInputValue'),'"')

In Yes block, Expression in Compose 2:
trim(replace(substring(outputs('Compose'),0,indexOf(outputs('Compose'),':')),'"',''))

Append to array variable: Collecting the matching keys into array

Writing the output in Compose 4
