JSON处理使用Rapidminer金桥运营商

Somnath_Das

I have simple JSON data in the format as follows:

{"A":"a1","B":"b1"}

{"A":"a2","B":"b2"}

{"A":"a3","B":"b3"}

I want the output in the format:
A B
a1 b1
a2 b2
a3 b3

Please help, it is urgent

Hi,

when I try your input on jqplay.org with the filter [.A, .B] |@csv, it returns the correct output.

The library used in the RapidMiner extension only returns the first element though. I'm not sure what to do there.

输入有点反常啊,因为这是一个列表f objects, but not in a syntactically explicit way.

When changing the input to this:

[

{"A":"a1","B":"b1"},

{"A":"a2","B":"b2"},

{"A":"a3","B":"b3"}
]
it works with the filter.[] | [.A, .B].

Example process:

< ?xml version = " 1.0 " encoding = " utf - 8 " ?> <过程版本sion="9.8.001">   
                                                                            

With this input the output of "JSON to Data" is also meaningful.

Regards,

Balázs
