Nested JSON and never end Records

‎02-27-2017 06:43 PM

Afternoon,

 

I have a json file (https://1drv.ms/u/s!At8Q-ZbRnAj8hkJLL1cyU4t_hoHC) which has many nested arrays and I'm unsure of how to extract all of the records into powerbi.

 

I've watch the guyinacube video (incredibly helpful), but I get to a point where I can't expand my columns any further yet I need the data inside that record (it's actually the data I want).

 

First step: https://gyazo.com/86e411d5de9d7f2f52813f6f66cb3bf9

Convert to table, easy it converts out to this.

 

Second Step: https://gyazo.com/546206f9a6b0459a4a09b2c865c3d902

Expand out, again comfortable. Expand again.

 

Third Step (issue): https://gyazo.com/ffe36ce86fa91f4ae0a435c524d026e5

The column on the far right is the colum which contains the data that i want, but I'm unable to retrieve the data from that column without individually clicking on the links.

 

Any ideas as to how I would be to produce rows or tables from this?

Here is the final result that you can follow

 

let
    json= Json.Document(File.Contents("D:\Downloads\Xero Datapowerbiforum")),
    json_tab = Table.FromList(json, Splitter.SplitByNothing()),
    expand_1 = Table.ExpandRecordColumn(json_tab, "Column1", {"JournalID", "JournalDate", "JournalNumber", "CreatedDateUTC", "SourceID", "SourceType", "JournalLines"}),
    expand_2 = Table.ExpandRecordColumn(expand_1, "JournalLines", {"JournalLine"}),
    journal_line_transform = Table.TransformColumns(expand_2, {"JournalLine", each if _ is record then {_}  else _}),
    expand_3 = Table.ExpandListColumn(journal_line_transform, "JournalLine"),
    expand_4 = Table.ExpandRecordColumn(expand_3, "JournalLine", {"JournalLineID", "AccountID", "AccountCode", "AccountType", "AccountName", "Description", "NetAmount", "GrossAmount", "TaxAmount", "TaxType", "TaxName"}, {"JournalLineID", "AccountID", "AccountCode", "AccountType", "AccountName", "Description", "NetAmount", "GrossAmount", "TaxAmount", "TaxType", "TaxName"})
in
    expand_4

Keyboard Shortcut to "Toggle Line Comments" in DBeaver

-
Image
In DBeaver, "Ctrl+/" is the default shortcut to Toggle Line Comments. However, in keyboards without a dedicated / key, this may not work out of the box. In my case, the / is obtained with "Shift+7", which means I'd need to set "Ctrl+Shit+7" as the shortcut,  which DBeaver uses by default as the shortcut to "Activate results/panel": So, to set enable the Toggle Line Comments, I needed to remove the "Activate results/panel" configuration from the Preferences and I'm now able to use "Ctrl+Shit+7" for the Toggle Line Comments.
