Expand Record from a column

[Alexandra_B]

Hello.

I am using an API to get the data from a Shelly device:

The script is:

let
    // Define the URL
    url = "https://shelly-<xx>-eu.shelly.cloud/device/status",

    // Define the request body
    requestBody = Text.ToBinary("id=<device_ID>&auth_key=<API_Key>"),

    // Define the headers (if needed)
    headers = [
        #"Content-Type" = "application/x-www-form-urlencoded"
    ],

    // Make the POST request
    response = Web.Contents(url, [
        Headers = headers,
        Content = requestBody
    ]),

    // Parse the JSON response
    jsonResponse = Json.Document(response),
    
    // Access the 'data' field
    data = jsonResponse[data],

    // Access the 'device_status' field
    device_status = data[device_status],

    // Convert the record to a table for easier expansion
    device_status_table = Record.ToTable(device_status)
in
    device_status_table

Then, my result is this:

I am trying to get the Record values in each column, but I don`t know how to do it quickly enough, and not one at a time, as the results of the API are like this:

"device_status":

{"mqtt":{"connected":false},
"switch:0":{"id":0,"aenergy":{"by_minute":[0,0,0],"minute_ts":1717071958,"total":0},"source":"init","output":false,"apower":0,"voltage":249.4,"current":0,"pf":0,"temperature":{"tC":31.3,"tF":88.4}},

"ble":[],

"id":"<device_id>",

"_updated":"2024-05-30 12:26:28",

"input:0":{"id":0,"state":false},

"v_eve:0":{"ev":"","ttl":-1,"id":0},

"eth":{"ip":null},

"ts":1717071960.41,

"code":"codeU",

"v_eve:1":{"ev":"","ttl":-1,"id":1},

"input:1":{"id":1,"state":false},

"serial":940,

"wifi":{"sta_ip":"192.x.x.x","status":"got ip","ssid":"<WiFi_name>","rssi":-65},

"cloud":{"connected":true},

"sys":{"mac":"<mac_address>","restart_required":false,"time":"11:14","unixtime":1717064091,"uptime":20691,"ram_size":238928,"ram_free":142096,"fs_size":524288,"fs_free":282624,"cfg_rev":9,"available_updates":{"stable":{"version":"1.3.2"}}}}}}

Please, could you share your experience?

Thank you.

Thank you, everyone.
I ended up adding Custom Columns based on the following formula (adapted for each column):

if 
   Value.Is ([Value], type record) 
   then 
        Record.Field([Value], "connected") 
else 
    ""

Resulting in:

  

Thank you for your support.

Hi @Alexandra_B 

You can explore Record functions in Power Query from the following documentation. As all records don't share the same fields, you need to first filter the required fields and analyze which ones need to be organized into the same column. Then we can explore how to expand it more efficiently. 

Record functions - PowerQuery M | Microsoft Learn

If you only want to expand all records into Text format in a column, you can try the solution from below thread:

You won't have much of a choice as you have nested records too.  You will need to decide which records to keep, which to throw away, and how to flatten the hierarchies.  Not really something you can do automatically.
