Goodreads Normalizer

A Python library and command-line application for cleaning, validating, and normalizing Goodreads library exports.

Goodreads exports are an excellent way to back up your library, but the exported data is often inconsistent. Author names, series information, ISBNs, dates, shelves, and other metadata can vary significantly, making it difficult to analyse, migrate, or integrate with other cataloguing systems.

Goodreads Normalizer provides deterministic normalization using strongly typed Pydantic models, allowing your Goodreads data to be transformed into clean, validated, machine-readable records.

Why This Project?

Goodreads has existed for many years, and its export format reflects that history.

Some common issues include:

• inconsistent author names
• editors included as authors
• translators stored inconsistently
• multiple spellings of the same person
• incomplete or malformed series data
• inconsistent ISBN formatting
• missing or duplicated values

This project aims to normalize these inconsistencies while preserving the original information wherever possible.

The goal is predictable, repeatable normalization, not automatic guessing.

Installation

Using pip

pip install goodreads-normalizer

Using uv

uv add goodreads-normalizer

---

Command Line Usage

Normalize a Goodreads export:

goodreads-normalizer \
    --file goodreads_export.csv \
    --output normalized.csv

or

goodreads-normalizer -f goodreads_export.csv -o normalized.csv

Display help:

goodreads-normalizer --help

What Gets Normalized?

Current areas include:

• Author names
• Editors
• Translators
• Narrators
• Series names
• Series numbers
• ISBN values
• Empty values
• Date parsing
• Validation

The project deliberately avoids changing data that cannot be normalized with confidence.
