JSON object to array

Hello. 


I'm trying out Flow a little deeper and have lots of questions (fun!).

 

Simple project:

  1. Hit the Github emoji api
  2. Get all emojis
  3. Convert from JSON object to array(?)
  4. Send all emojis to a sharepoint list with two columns
    1. emoji_name
    2. url

So far:

  1. Created the Sharepoint list with 2 columns correctly named
  2. Created the HTTP GET request to https://api.github.com/emojis
  3. It returns a JSON object of all emojis
  4. I cant seem to find a way to convert this from JSON object to somthing Sharepoint will ingest. 

Any ideas? 

 

Thanks

Hi @seadude

 

I create a flow to solve your problem.

 

Starting with your step 3,

 

 

Using a Compose action we can split each line using the ',', don't forget replace the '{' and '}'. The expression that you need is:

 

split(replace(replace(string(body('YOUR HTTP ACTION NAME')),'{',''),'}',''),',')

After i use a apply to each and inside split the 'key'(name of emoji) and 'value'(url of emoji)

To get it respectively use this expressions:

 

first(split(items('YOUR APPLY TO EACH NAME'),':'))
last(split(items('YOUR APPLY TO EACH NAME'),':'))

The result is this:Flow 1.png

 

 

 

After this is easy to insert in SP using the Create Item action

 

Look at my flow result:

Hello @gamoraes

 

I'm working my way through your answer. 

 

What do you mean by 'YOUR HTTP ACTION NAME' and 'YOUR APPLY TO EACH NAME'?

 

I feel like the name of my http action is 'HTTP', but that doesn't work in the expression. 

I feel like the name of my apply to each is the default "Apply to each", but that doesn't work in the expression.

Can you give me some more details? 

 

Thank you very much!

Looks like I was missing the "_" between spaced words in the "Apply to each" title.

 

When I changed the First and Last formulas to contain 'Apply_to_each', the Flow was successful! I can click the right and left arrows to move through the results. 

 

Awesome help @gamoraes. You have skills!

Aha! Notice though that the `Last` expression is actually cutting the `https:` off of the URL becuase of the " : ". Tricky. Do you have ideas how I can: 

 

  • Keep the `https:` prefix for the URL
  • Remove all " " " (double quotes) from the Name and Url?


Thanks for your time!

Hi @gamoraes

 

I figured this out with a little help from another buddy. All good now!

 

Thanks!

Hi @seadude.

 

Cool that you have win! 🙂

 

Just for knowledge here is the solutions for you:

 

DONT FORGET TO CHANGE THE ACTIONS NAME, IN THIS CASE 'Aplicar_a_cada' to your apply to each action name and 'Http' to your http action name

 

  • Keep the `https:` prefix for the URL
    • Replace the last compose script to
    • substring(items('Aplicar_a_cada'),add(indexOf(items('Aplicar_a_cada'),':'),1),sub(length(items('Aplicar_a_cada')),add(indexOf(items('Aplicar_a_cada'),':'),1)))
    • In this new function i use substring,i get the index of first ':' more 1(to remove this) and the length minus the index
  • Remove all " " " (double quotes) from the Name and Url?
    • Replace the old split in first compose to this
    • split(replace(replace(replace(string(body('HTTP')),'{',''),'}',''),'"',''),',')

My buddy and I hacked together this solution before your more elegant reply. It works too!

I've got one that could use some help if you've got this figured out.

I'm getting these JSON objects from an API call that I'd like to convert into an array of objects (Users).

 

2018-09-27_11-28-12.jpg

I've tried replacing the "users" object brackets to square brackets but then it doesn't like the IDs and ":" before each array item. not sure how to replace those, as they can be any number and have any number of users returned.

 

I presume that after I get the string looking right, I can just pass that string into a parse JSON action and get an array I can loop through.

Good question. I haven't touched this one in a while and you know how that goes!

 

I think you're asking how to loop through the deeper levels of your JSON object and pull out the values, right?

 

I spent a few minutes looking through the Flow we came up with. Its different from yours, my objects are only one level deep.

 

Example:

{
  "100": "https://assets-cdn.github.com/images/icons/emoji/unicode/1f4af.png?v8",
  "1234": "https://assets-cdn.github.com/images/icons/emoji/unicode/1f522.png?v8",
  "+1": "https://assets-cdn.github.com/images/icons/emoji/unicode/1f44d.png?v8",
  "-1": "https://assets-cdn.github.com/images/icons/emoji/unicode/1f44e.png?v8",
  "1st_place_medal": "https://assets-cdn.github.com/images/icons/emoji/unicode

}

I'm just now sure! I exported my Flow and can email it to you if its of any use. Reaching out to @gamoraes here, he's solid in this area.

 

 

I can get it down to the displayed JSON  where each user object is under "users" but users isn't an array so each user is an object. with some simple regex-find/replace I am able to format the JSON in a way that it works, but I am unable to see a suitable way to handle that in the flow without buying another subscription to another service...

I'll do some more digging.

Thanks

Hi @Shegs. Just ran across a new @mr-dang video here. Check out the 14:00 mark. It appears he is using an Expression to dig a level deeper into the JSON.

 

Maybe it could help?

I actually found an amazing fix.

I was able to take the function on this page:

https://www.red-gate.com/simple-talk/sql/t-sql-programming/consuming-json-strings-in-sql-server/

 

and create a query that pivoted my JSON into rows that were then returned to flow as an array.
