surveyflow

A Python library for processing survey data — parse survey definitions and responses into structured outputs ready for analysis.

Features

Parse survey definition (question structure, types, positions) into metadata.json
Parse survey response rows into rawdata.csv with numeric codes
- Single-choice → integer code (e.g. 1)
- Multi-choice / ranking → semicolon-separated codes (e.g. "1;3;5")
- Open-ended / matrix / number → raw text
Filter responses by status (default: approved only)
Consistent columns between rawdata.csv and metadata.json

Installation

pip install surveyflow

Quick Start

from surveyflow.steps.ingestion import IngestionStep

# definition: dict from your survey platform's definition API
# rows_pages: list of paginated response pages from your survey platform

step = IngestionStep()
context = step.run({
    "definition":  definition,
    "rows_pages":  rows_pages,
    "output_dir":  "./output",
})

df       = context["rawdata"]      # pandas DataFrame
metadata = context["metadata"]     # dict with question info + value labels

Output

`rawdata.csv`

task_id	date_time	q6	q7	q10	q18
task_001	2026-03-01	1	2	1	1;3
task_002	2026-03-01	2	1	2	2
