Parsing a .json column in Power BI

Question

I want to parse a .json column through Power BI. I have imported the data directly from the server and have a .json column in the data along with other columns. Is there a way to parse this json column?

Example:

       Key      IDNumber    Module      JsonResult  
       012      200         Dine        {"CategoryType":"dining","City":"mumbai"',"Location":"all"} 
       97       303         Fly         {"JourneyType":"Return","Origin":"Mumbai (BOM)","Destination":"Chennai (MAA)","DepartureDate":"20-Oct-2016","ReturnDate":"21-Oct-2016","FlyAdult":"1","FlyChildren":"0","FlyInfant":"0","PromoCode":""} 
       276      6303        Stay        {"Destination":"Clarion Chennai","CheckInDate":"14-Oct-2016","CheckOutDate":"15-Oct-2016","Rooms":"1","NoOfPax":"2","NoOfAdult":"2","NoOfChildren":"0"}

I wish to retain the other columns and also get the simplified parsed columns.

Answer 1

There is an easier way to do it, in the Query Editor on the column you want to read as a json:

• Right click on the column
• Select Transform>JSON

then the column becomes a Record that you can split in every property of the json using the button on the top right corner.

Answer 2

Use Json.Document function like this

let
    ...
    your_table=imported_the_data_directly_from_the_server,
    json=Table.AddColumn(your_table, "NewColName", each Json.Document([JsonResult]))
in
    json

And then expand record to table using Table.ExpandRecordColumn

Or by clicking this button

Answer 3

Use Json.Document() function to convert string to Json data.

let
    Source = Json.Document(Json.Document(Web.Contents("http://localhost:18091/pools/default/buckets/Aggregation/docs/AvgSumAssuredByProduct"))[json]),
    #"Converted to Table" = Record.ToTable(Source),
    #"Filtered Rows" = Table.SelectRows(#"Converted to Table", each not Text.Contains([Name], "type_")),
    #"Renamed Columns" = Table.RenameColumns(#"Filtered Rows",{{"Name", "AvgSumAssuredByProduct"}}),
    #"Changed Type" = Table.TransformColumnTypes(#"Renamed Columns",{{"Value", type number}})
in
    #"Changed Type"

Answer 4

import json
from urllib import urlopen
import string
from UserList import *
l=[]
j=[]
d_base=urlopen('https://api.thingspeak.com/channels/193888/fields/1.json?results=1')
data = json.load(d_base)
for k in data['feeds']:
        name = k['entry_id']
        value = k['field1']
        l.append(name)
        j.append(value)

print l[0]
print j[0]
