path_or_buf : the path or buffer to write the result string

if this is None, return a StringIO of the converted string

orient : string

• Series
  • default is ?index?
  • allowed values are: {?split?,?records?,?index?}
• DataFrame
  • default is ?columns?
  • allowed values are: {?split?,?records?,?index?,?columns?,?values?}
• The format of the JSON string
  • split : dict like {index -> [index], columns -> [columns], data -> [values]}
  • records : list like [{column -> value}, ... , {column -> value}]
  • index : dict like {index -> {column -> value}}
  • columns : dict like {column -> {index -> value}}
  • values : just the values array

date_format : {?epoch?, ?iso?}

Type of date conversion. epoch = epoch milliseconds, iso` = ISO8601, default is epoch.

double_precision : The number of decimal places to use when encoding

force_ascii : force encoded string to be ASCII, default True.

date_unit : string, default ?ms? (milliseconds)

default_handler : callable, default None

Handler to call if object cannot otherwise be converted to a suitable format for JSON. Should receive a single argument which is the object to convert and return a serialisable object.

lines : boolean, defalut False

If ?orient? is ?records? write out line delimited json format. Will throw ValueError if incorrect ?orient? since others are not list like.
