jsoncsv : easily convert json to csv or xls[x]
jsoncsv (with mkexcel) is a command tool to convert json file to csv/xlsx file.
It’s simple, and no need user to specify the keys.
Just use them.
Quick Start :
cat the raw.json to csv/xls use command line tool
cat raw.json | jsoncsv | mkexcel > output.csv
cat raw.json | jsoncsv | mkexcel -t xls > output.xlsmake sure each line of raw json text file is a json object
$cat raw.json
{"id":1, "name":"A", "year": 2015}
{"id":2, "name":"S", "zone": "china"}
$cat raw.json | jsoncsv | mkexcel > output.csv
$cat output.csv
id,name,year,zone
1,A,2015,
2,S,,chinaThis is easily and needn’t care the different keys from any two object.
if input file is an json_array, use -A/–array to decode it
$cat raw.json
[{"id":1, "name":"A", "year": 2015}, {"id":2, "name":"S", "zone": "china"}]
$cat raw.json | jsoncsv -A | mkexcel > output.csv
$cat output.csv
id,name,year,zone
1,A,2015,
2,S,,chinaanother way to convert file step by step
$jsoncsv raw.json expand.json
$mkexcel expand.json -t xls output.xlsget more options with –help.
jsoncsv --help
mkexcel --helpInstall
pip install jsoncsvUsage
see #QuickStart and get more options with –help.
just expand/restore the json, the expand json is one layer json.
jsoncsv raw.json expand.json
jsoncsv -r expand.json raw.json
cat raw.json | jsoncsv | jsoncsv -r > raw2.jsonmkexcel the expanded json (one layer)
mkexcel expand.json output.csv
mkexcel -t xls expand.json > output.xls
mkexcel -t csv expand.json > output.csv-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}]} will transformed to {“s.2.w”: 1,”s.0”: 1,”s.1”: 2}
the output “expand.json” is only one layer json, it can be easy change to csv or xlsx (with mkexcel)
-r, –restore
restore the expanded json 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 file
mkexcel expand.json output.csv-t, –type
chose dump type in [‘csv’, ‘xls’] default is ‘csv’
cat expand.json|mkexcel -t csv > output.csv
cat expand.json|mkexcel -t xls > output.xlsNOTE/TODO
1. dict keys can’t be just array indexes
example:
echo '{"0":1,"1":[1,2]}'|jsoncsv -e| jsoncsv -r
[1, [1, 2]]2. mkexcel enable hooks
wait next next version
3. unicodecsv is not good enough
but better than python strand library csv.
4. Windows is poor support
