将 JSON 转换为 CSV 的最简单方法（包括数组到字段）

Question

I'm trying to convert my parse.com json data into a csv file, except I have a column of type array, and would like each number within each array to be saved within it's own field.

What's the easiest way to do this using the command line or javascript?

I've tried several online converters but they fail because my data is too large. I'm mainly looking for an answer from someone who has converted parse data to the csv format successfully.

Yow might want to use a script, python or php, parse the data in batches, and also write the file in batches of lines by retaining the number of line at some point ( in any case when script fails ) and go back and write from that line. A quick pseudo-code example. based on your attachment

If your json it's formatted line by line :

Read file , 10 lines at a time

batch = 1000 // sample
current = 0
while (current<batch) 

for each line :
   json_decode() -> create csv string "1,2,3,3.." etc,
   write line by appending to file 
   save line number

   current++
end for
