Question

我有一个名为“test.json”的json文件，如下所示，并希望将其转换为CSV文件。我尝试过python pandas，但遗憾的是没有成功。任何人的帮助都会非常感激。

Answer 1

以下是使用jq的解决方案。

如果filter.jq包含以下过滤器

  [ .header | match("[^: ]+";"g") | .string ]
, ( .data   | keys[] as $k  | [$k] + .[$k] )
| @csv

和data.json包含示例数据

$ jq -M -r -f filter.jq data.json

产生

"mac[#mode|_rate]","latitude","longitude","range","max","age","sig_A","noise_A","sig_B","noise_B","num","loss","kBps"
"04:e5:48:01:73:29#0000",48.14998,11.583327,-1,0,0,-80,-101,-96,-98,2,0,0.138

Answer 2

使用jsonlite和dplyr的其他解决方案：

install.packages(c("jsonlite","dplyr"))
library(jsonlite)
library(dplyr)

# asumme your file is "my_file.json"
my_data <- as_tibble(fromJSON("my_file.json"))

需要协助将json文件转换为CSV
