Mimesis is a package for Python, which helps generate big volumes of fake data for a variety of purposes in a variety of languages. The fake data could be used to populate a testing database, create beautiful JSON and XML files, anonymize data taken from production and etc.

To install mimesis, simply use pip:

[env] ~ ⟩ pip install mimesis

This library is really easy to use and everything you need is just import an object which represents a type of data you need (we call such object Provider).

In example below we import provider Person, which represents data related to personal information, such as name, surname, email and etc:

>>> from mimesis import Person
>>> person = Person('en')

>>> person.full_name()
'Antonetta Garrison'

>>> person.occupation()
'Backend Developer'

>>> person.telephone()
'1-408-855-5063'

More about the other providers you can read in our documentation.

Mimesis currently includes support for 33 different locales. You can specify a locale when creating providers and they will return data that is appropriate for the language or country associated with that locale.

Let's take a look how it works:

>>> from mimesis import Person
>>> from mimesis.enums import Gender

>>> de = Person('de')
>>> en = Person('en')

>>> de.full_name(gender=Gender.FEMALE)
'Sabrina Gutermuth'

>>> en.full_name(gender=Gender.MALE)
'Layne Gallagher'

Mimesis support over twenty different data providers available, which can produce data related to people, food, computer hardware, transportation, addresses, and more.

See API Reference for more info.

You can generate dictionaries which can be easily converted to any format you want (JSON/XML/YAML etc.) with any structure you want.

Just use object Field() as shown below:

>>> from mimesis.schema import Field, Schema
>>> from mimesis.enums import Gender
>>> _ = Field('en')
>>> description = (
...     lambda: {
...         'id': _('uuid'),
...         'name': _('text.word'),
...         'version': _('version', pre_release=True),
...         'timestamp': _('timestamp', posix=False),
...         'owner': {
...             'email': _('person.email', key=str.lower),
...             'token': _('token_hex'),
...             'creator': _('full_name', gender=Gender.FEMALE),
...         },
...     }
... )
>>> schema = Schema(schema=description)
>>> schema.create(iterations=1)

Output:

[
  {
    'id': '7a41f446-57a8-ec17-b9ad-367742251679',
    'name': 'desert',
    'version': '7.3.7-alpha.6',
    'timestamp': '2026-06-06T14:00:52Z',
    'owner': {
      'email': '[email protected]',
      'token': 'acfd799af9b46e5560a51dabace593033171ec81e997905acfc602c93a741735',
      'creator': 'Keena Hendricks'
    }
  }
