Help with this JSON

Hi all,

 

I'm hoping to expand some json into a table but because of the way the json is structured, the values I need end up as column headers instead of row values. Has anyone run into this before?

 

Example of json input:

2019-12-30_15h45_48.png

 

What happens in PowerBI:

Desired end state of query should result in a table like this:

Additionally, if I expand the "50" column then the "50" is wiped out by the next record "101" which is in turn wiped out by "140" etc down the line. Renaming the expanded column doesn't help. Power Query:

let
Source = Json.Document(Web.Contents("APIurl")),
data = Source[data],
attendance = data[attendance],
#"Converted to Table" = Record.ToTable(attendance),
#"Expanded Value" = Table.ExpandRecordColumn(#"Converted to Table", "Value", {"50"}, {"50"}),
#"Expanded 50" = Table.ExpandRecordColumn(#"Expanded Value", "50", {"101"}, {"101"}),
#"Expanded 101" = Table.ExpandRecordColumn(#"Expanded 50", "101", {"140"}, {"140"})
in
#"Expanded 101"

 

Does anyone know a way to achieve this? Is this just bad json?

 

Thank you,
UIT

Hello

To me it seems that this json has all nested objects with the real data only after 4th level. Don't know what this ids are doing there.
You could try this function to extract all data https://www.thebiccountant.com/2018/06/17/automatically-expand-all-fields-from-a-json-document-in-po...

Hope this helps
