具有已知结构的对象的可能巨大的JSON行文件将被转换成具有头部的CSV。
范例

{"name":"name_0","value_a":"value_a_0","value_b":"val_b_0"}
{"name":"name_1","value_a":"value_a_1","value_b":"val_b_1"}
{"name":"name_2","value_a":"value_a_2","value_b":"val_b_2"}
{"name":"name_3","value_a":"value_a_3","value_b":"val_b_3"}
{"name":"name_4","value_a":"value_a_4","value_b":"val_b_4"}

期望产量

"name","value_a","value_b"
"name_0","value_a_0","val_b_0"
"name_1","value_a_1","val_b_1"
"name_2","value_a_2","val_b_2"
"name_3","value_a_3","val_b_3"
"name_4","value_a_4","val_b_4"

正在审理中

(if (input_line_number == 1 ) then ([.|to_entries|.[].key]|@csv) else empty end), 
(.|to_entries|[.[].value]|@csv  )

然而，这依赖于json中的顺序，作为一种替代方法，我将其替换为直接按照我想要的顺序选择值。

(if (input_line_number == 1 ) then ("\"name\",\"value_a\",\"value_b\"") else empty end), (.|[.name?,.value_a?,.value_b?]|@csv  )

有没有更好的解决办法？尤其是关于if，因为它感觉很笨重。
我主要不想使用slurp，因为它会将整个文件加载到内存中
