我正在从firebase下载数据,将其导出到json中。在此之后我尝试将其上传到bigquery但我需要删除新的换行符以进行大查询以接受它。
这是我从firebase收到它的方式。

这就是我需要的方法,但除了手动操作之外无法弄清楚如何做到这一点。

我正在使用python加载json,读取它然后写一个新的但无法弄清楚正确的代码。谢谢!
这是我的python代码的大纲
import json
with open('nospacetest.json', 'r') as f:
data_json=json.load(f)
#b= to file afte code for no line breaks is added
with open('testnoline.json', 'w') as outfile:
json.dump=(b, outfile)
答案 0 :(得分:2)
你可以使用str.replace()替换任何新行:
new_json_str = old_json_str.replace('\n', ' ')
