It has not ready to be use as a module. :(

jsoncsv raw.json expand.json

mkexcel expand.json -o output.csv
mkexcel expand.json -t xls -o output.csv

jsoncsv --help

jsoncsv

example：

echo '{"s":[1,2,{"w":1}]}'|jsoncsv
{"s.2.w": 1,"s.0": 1,"s.1": 2}

-e, –expand

expand json, 展开 json

jsoncsv -e raw.json expand.json
cat raw.json expand.json
{"s":[1,2,{"w":1}]}
{"s.2.w": 1,"s.0": 1,"s.1": 2}

{“s”:[1,2,{“w”:1}]} transformed to {“s.2.w”: 1,”s.0”: 1,”s.1”: 2}

expand.json is only one layer json, it can be easy change to csv or xlsx

-r,–restore

restore 重构被展开的json

jsoncsv -r expand.json raw.json
cat expand.json raw.json
{"s.2.w": 1,"s.0": 1,"s.1": 2}
{"s": [1, 2, {"w": 1}]}

{“s.2.w”: 1,”s.0”: 1,”s.1”: 2} change to {“s”:[1,2,{“w”:1}]}

-s,–separator

separator used for combine the keys in the tree

default separator is .

–safe

on safe mode, use escape separator to avoid confilct

expand:

[‘aa’, ‘bb’, ‘www.xxx.com’] –> ‘aa.bb.www.xxx.com’

restore:

‘aa.bb.www.xxx.com’ –> [‘aa’, ‘bb’, ‘www.xxx.com’]

mkexcel

dump expanded (by jsoncsv) json file to csv or xls

将**jsoncsv** expand 的 json文件转成 csv/xls

mkexcel expand.json -o output.csv
cat expand.json|mkexcel > output.csv
cat expnad.json|mkexcel -t xls > output.xls

-t,–type

chose dump type in [‘csv’, ‘xls’]

cat expand.json|mkexcel -t csv > output.csv
cat expand.json|mkexcel -t xls > output.xls

NOTE/TODO

1. key can’t be all intenger string

example:

echo '{"0":1,"1":[1,2]}'|jsoncsv -e| jsoncsv -r
[1, [1, 2]]

如果要考虑，实现方案会过于复杂，不想考虑在expand的json中添加类型信息

2. write in xlsx is always str
