Pretty Print JSON (Formatter, Beautifier)

See more JSON Examples

Demonstrates how to emit JSON in a pretty, human-readable format with indenting of nested arrays and objects. Ruby

require 'chilkat'

success = false

json = Chilkat::CkJsonObject.new()

jsonStr = "{\"name\": \"donut\",\"image\":{\"fname\": \"donut.jpg\",\"w\": 200,\"h\": 200},\"thumbnail\":{\"fname\": \"donutThumb.jpg\",\"w\": 32,\"h\": 32}}"

success = json.Load(jsonStr)
if (success != true)
    print json.lastErrorText() + "\n";
    exit
end

# To pretty-print, set the EmitCompact property equal to false
json.put_EmitCompact(false)

# If bare-LF line endings are desired, turn off EmitCrLf
# Otherwise CRLF line endings are emitted.
json.put_EmitCrLf(false)

# Emit the formatted JSON:
print json.emit() + "\n";
