[英]Parsing a .json column in Power BI
我想通过Power BI解析.json列。 我已经直接从服务器导入了数据,并且在数据中还有一个.json列以及其他列。 有没有办法解析此json列?
例:
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"}
我希望保留其他列,并获得简化的解析列。
使用Json.Document()
函数将字符串转换为Json数据。
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"
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]
