json2properties
Simple tool that converts JSON files to equivalent content in Java properties format. Nested structures are flattened to fit properties key-value format. Provides reverse operation as well.
Example
Source (JSON)
{
"a": 1,
"b": "two",
"c": [1, 2, 3],
"d": {
"k": 123,
"l": "asd",
"m": {
"types": "hash",
"and": ["ar", "ra", "y"]
}
}
}
Destination (.properties)
a=1
b=two
c.0=1
c.1=2
c.2=3
d.k=123
d.l=asd
d.m.types=hash
d.m.and.0=ar
d.m.and.1=ra
d.m.and.2=y
Usage
Shell
$ gem install json2propeties
$ json2propeties input.json output.properties
# to perform reverse conversion:
$ propeties2json input.properties output.json
Code
# Assuming gem has been installed
require 'json2propeties'
converter = Json2properties.new
# Convert json to properties
converter.convert_file('/tmp/input.json', '/tmp/output.properties')
# Convert properties to json
converter.unconvert_file('/tmp/input.properties', '/tmp/output.json')
# Convert JSON string to flattened key-value Hash
json = JSON.generate({
a: 1,
h: {
x: 1,
y: 2
},
a: [4, 5, 6]
})
props = converter.json2kv(json)
# props == {
"a" => 1,
"h.x" => 1,
"h.y" => 2,
"a.0" => 4,
"a.1" => 5,
"a.2" => 6,
}
# reverse action
reverse_engineered_json = converter.kv2json(props)
