JSON data from Google Big Query not interpreted correctly once extracted in Power BI

[PC2790]

Hello guys,

So I am working on this piece of work where I am trying to fetch Google Big Query data in Power BI, however when I do that in normal tabular format, it comes out to be somewhat gibberish.

Something like below:

This is useless to me as I cannot use thi sdata as required.

I stumbled upon a similar post -https://community.powerbi.com/t5/Desktop/How-to-resolve-Nested-Big-Query-Data/td-p/1327846 and can see that it is marked as an Solved, however I am not able to figure out how.

Can anyone please advise how this can be approached please?

P.S- As the data is sensitive, I won't be able to share the data. If there is any other wa, please donot hesitate to suggest.

Thankyou in advance

Finally I reached to a conclusion here where I am Unnesting the columns in Google Big Query, saving them as views and then consuming them in Power BI.

Prerequisite is that you have some background knowledge of writing queries in Google Big Query.

Some information on the queries can be found here:

https://cloud.google.com/bigquery/docs/reference/standard-sql/query-syntax#unnest_operator

So when I try to download the data in the offline mode as JSON format and the load in Power BI as JSON, it works fine.

So what I am not doing is UNNESTING the data as:

Select *, co.value

from <table> as tablename,

UNNEST(NestedColumnname) as co

I am looking for ways to get this query saved as view so that I can consume it in Power BI

Hi @PC2790 

Please check whether there are other tables in the Navigator Pane. Maybe some tables contains proper data.
