Python API for SurveyJS Creator (Form Builder) schema and Form response JSON.

For information about the SurveyJS project, see https://surveyjs.io

Introduction

surveyjs is a Python package that loads and transforms SurveyJS Creator (Form Builder) JSON schema and Form response JSON into usable Python objects.

Its main aim is to provide easy access to a SurveyJS Form's questions (fields, layout elements, etc.) also captured as Python objects, which makes this API very versatile and usable.

Notes about terms:

• SurveyCreator: The Survey Creator (form builder) that defines the structure and design of a Form, with a schema in JSON format.
• SurveyForm: A filled-in or completed survey form, i.e. a form response or submission, with data in JSON format.
• Question: Represents a form field, ranging from simple input types (e.g. text, checkbox, rating) to more complex elements (e.g. matrix).
• Layout: A structural element such as a page, panel, or dynamic panel that can contain other elements, including questions and nested layouts.
• Element: The base concept for both Question and Layout elements in SurveyJS.

SurveyJS question and layout classes (source code):
https://github.com/surveyjs/survey-library/tree/master/packages/survey-core/src
The file prefix question indicates a question (field) class.

Features

• Compatible with Python 3.8 and later.
• Constructor of the SurveyCreator and SurveyForm class only requires the JSON (string or dict) and an optional language code (e.g. 'en', 'fr', etc.) for localization of questions (e.g. titles and choices).
• Get a SurveyForm object's Questions as usable Python objects e.g. datetime, boolean, list (for checkbox), dict (for matrix) etc.
• Support for all SurveyJS question types.
• Open source (MIT License).

PyPI - Python Package Index

Binary installers for the latest released version are available at the Python Package Index.

pip install surveyjs

Source Install with pip

git clone [e-mail]:novacode-nl/python-surveyjs.git

Using direnv

You can use nixpkgs to run a self-contained Python environment without any additional setup.
Once you've installed nixpkgs, switch into the directory and type "nix-shell" to get a shell from which the correct Python with packages is available.

If you're using direnv, use direnv allow after changing into the project directory and you're good to go.
Also consider nix-direnv to speed up the experience (it can re-use a cached local installation).

Usage Examples

from surveyjs import SurveyCreator, SurveyForm

# survey_json is a SurveyJS Creator JSON schema (string or dict)
# form_json is a SurveyJS Form submission JSON (string or dict)

creator = SurveyCreator(survey_json)
form = SurveyForm(form_json, creator)

# Text question
print(form.questions['firstName'].label)
# 'First Name'

print(form.questions['firstName'].value)
# 'Bob'

# Checkbox question
print(form.questions['colors'].value)
# ['red', 'blue']

# Rating question
print(form.questions['satisfaction'].value)
# 4

# Boolean question
print(form.questions['agree'].value)
# True

# Matrix question
print(form.questions['quality'].value)
# {'affordable': 'good', 'does-what-it-claims': 'excellent'}

# Panel element
print(form.elements['personal_data'])
# <QuestionPanel>
