Sort field names alphabetically in JSON source data

[darshthakkar]

Hi Team,

I have my source data coming in JSON format. I want to sort the fields inside the JSON format alphabetically. One way is to use a mapper and arrange them one-one alphabetically but it is a tedious task if the fields are more. Can we use an expression in mapper or any other snap that does this for us?

Thank you.

Best Regards,
Darsh

Hi @darshthakkar,

One approach will be to Map the input document with the following expression:

$.entries().sort((a,b) => a[0].localeCompare(b[0])).reduce((acc,curr) => acc.extend({[curr[0]]:curr[1]}),{})

Note: This will only sort properties on first level.

Let me know if this helps.

BR,
Aleksandar.

Thank you @AleksandarAngelevski for your suggestion.
I will try it out and keep you posted with my findings…

@AleksandarAngelevski - You’re right, Alphabetical sorting doesn’t work on the first level so you’ll have to break that hierarchy and once you’re at the final stage, your expression will definitely work, I’ve tested it and can confirm that it works.

@AleksandarAngelevski - Is it a safe assumption that we can use the same expression with a minor tweak to organize data alphabetically even if it’s not the JSON format?
