lethe-cli 0.1.1

Data anonymization CLI tool

Lethe

Data anonymization CLI for structured files. Detect and replace PII in CSV, TSV, and plain text using Presidio and spaCy NER, with Faker-generated replacements that stay consistent across your dataset.

Install

pip install lethe-cli
python -m spacy download en_core_web_trf

For a faster, lighter model instead of the transformer:

python -m spacy download en_core_web_sm

Usage

Anonymize

Replace detected PII with consistent fake values:

lethe anonymize data.csv -o anonymized.csv
lethe anonymize data.csv --model sm --threshold 0.7
lethe anonymize notes.txt -o clean.txt --locale nl_NL

Multiply

Generate synthetic rows from an existing dataset:

lethe multiply data.csv --factor 5 -o expanded.csv
lethe multiply data.csv --factor 10 --sanitize --seed 42

Options

Run lethe anonymize --help or lethe multiply --help for the full list of options.
