将JSON流转换为CSV

Question

我想将文件中粘贴的JSON流（将近10,000）转换为具有特定格式的CSV文件以用于标题和值。

我JSON数据如下流：

{"shortUrlClicks":"594","longUrlClicks":"594","countries":[{"count":"125","id":"IQ"},{"count":"94","id":"US"},{"count":"56","id":"TR"},{"count":"50","id":"SA"},{"count":"29","id":"DE"},{"count":"24","id":"TN"},{"count":"20","id":"DZ"},{"count":"14","id":"EG"},{"count":"13","id":"MA"},{"count":"12","id":"PS"}],"browsers":[{"count":"350","id":"Chrome"},{"count":"100","id":"Firefox"},{"count":"46","id":"Safari"},{"count":"35","id":"Mobile"},{"count":"20","id":"Mobile Safari"},{"count":"20","id":"SamsungBrowser"},{"count":"8","id":"MSIE"},{"count":"6","id":"Opera"},{"count":"3","id":"OS;FBSV"},{"count":"2","id":"Maxthon"}],"platforms":[{"count":"227","id":"Android"},{"count":"221","id":"Windows"},{"count":"67","id":"iPhone"},{"count":"30","id":"X11"},{"count":"25","id":"Macintosh"},{"count":"8","id":"iPad"},{"count":"2","id":"Android 4.2.2"},{"count":"1","id":"Android 4.1.2"},{"count":"1","id":"Android 4.3"},{"count":"1","id":"Android 5.0.1"}],"referrers":[{"count":"340","id":"unknown"},{"count":"193","id":"t.co"},{"count":"38","id":"m.facebook.com"},{"count":"12","id":"addpost.it"},{"count":"4","id":"plus.google.com"},{"count":"3","id":"www.facebook.com"},{"count":"1","id":"goo.gl"},{"count":"1","id":"l.facebook.com"},{"count":"1","id":"lm.facebook.com"},{"count":"1","id":"plus.url.google.com"}]} 
{"shortUrlClicks":"594","longUrlClicks":"594","countries":[{"count":"125","id":"IQ"},{"count":"94","id":"US"},{"count":"56","id":"TR"},{"count":"50","id":"SA"},{"count":"29","id":"DE"},{"count":"24","id":"TN"},{"count":"20","id":"DZ"},{"count":"14","id":"EG"},{"count":"13","id":"MA"},{"count":"12","id":"PS"}],"browsers":[{"count":"350","id":"Chrome"},{"count":"100","id":"Firefox"},{"count":"46","id":"Safari"},{"count":"35","id":"Mobile"},{"count":"20","id":"Mobile Safari"},{"count":"20","id":"SamsungBrowser"},{"count":"8","id":"MSIE"},{"count":"6","id":"Opera"},{"count":"3","id":"OS;FBSV"},{"count":"2","id":"Maxthon"}],"platforms":[{"count":"227","id":"Android"},{"count":"221","id":"Windows"},{"count":"67","id":"iPhone"},{"count":"30","id":"X11"},{"count":"25","id":"Macintosh"},{"count":"8","id":"iPad"},{"count":"2","id":"Android 4.2.2"},{"count":"1","id":"Android 4.1.2"},{"count":"1","id":"Android 4.3"},{"count":"1","id":"Android 5.0.1"}],"referrers":[{"count":"340","id":"unknown"},{"count":"193","id":"t.co"},{"count":"38","id":"m.facebook.com"},{"count":"12","id":"addpost.it"},{"count":"4","id":"plus.google.com"},{"count":"3","id":"www.facebook.com"},{"count":"1","id":"goo.gl"},{"count":"1","id":"l.facebook.com"},{"count":"1","id":"lm.facebook.com"},{"count":"1","id":"plus.url.google.com"}]} 

...等等。

我想把它转换成这种形式CSV与任何标题（shortUrlclicks，longUrclicks等）：

我会感激，如果你能请帮我在相同。 Python或任何其他语言的任何代码将是有用的。

您可以使用Python标准库中的JSON库使用OS库（来自Python标准库）读取JSON和读/写文件。

这将是这样的：

f = File.open('file.json', 'r') 
items = json.loads(f.read()) 
csv_file = "" 

for row in items(): 
    new_row = "" 
    # get columns somehow 
    for column in columns: 
     new_row = "%s," % column 

    # Finished row, append a '\n' char to the row string. 
    csv_file.append("%s\n" % new_row) 

# write json file 
out = File.open('out.csv', 'rw') 
out.write(csv_file) 
out.close() 

PS：我没发布之前运行该代码。这是你的想法。

你可以使用熊猫来为你做这个。

看了你的JSON文件这样

DF = pandas.read_json（ 'filename.json'）

写入到csv

DF .to_csv（'filename.csv'，index = False）＃set index false如果你不需要它
