Not applicable

If you want a table with a variable number of columns, maybe you want to rethink your plan as it does not work well in powerbi. You might want to set a limit and then unpivot or something to have a stable number of columns

Hi,
Not thinking of keeping variable no.of columns. In case, the columns are not applicable they can be null - like the screenshot from Pat.
Or if all nested values can be captured in seprate rows thats also fine.

Hi @Krishanu 

 

You can combine tables with different headers, paste below M code in Advanced Editor with a blank query, see if it is what you want

Hi, @Vera_33 
It brings to the same position what Pat had shown. I have to go under these records too- see below screenshot and reply to Pat's response for details. Thanks for your help.

Hi @Krishanu 

 

I missed it...you have to do some click then...and I don't see I can go to lower level, simply use a function, but it stops here as the Json is not complete...just give you a little hint

What issue are you having?  I put your JSON code in a text file called ExampleJSON.json and used Get Data with the JSON connector to automatically get this this point.

Thanks Pat @mahoneypat  for responding.

If you see the last four records,  in serviceExceptionJson column it has nested records.

I need to expand them as well and there is no limit in number of nesting, I need to go upto the last level -  as long as the nesting goes and bring the data in separate columns/records in Power Query.

 

Also, I have some files where this serviceExceptionJson column is not present at all, just like initial set of records in your screenshot. Will I have to do something or Power Query automatically handles this?
