Data migration validation, reporting, and preflight toolkit.

migration-tools

A Python toolkit for data migration validation, preflight checks, and reporting.

Install

pip install migration-tools

Quick start

from migration_tools import (
    setup_logger,
    load_dataset,
    load_mapper,
    init_outputs,
    run_preflight_checks,
    check_output_date_formats,
    run_date_correlation_check,
    write_outputs,
    print_summary,
    generate_html_report,
)

logger = setup_logger(log_dir="logs")

data      = load_dataset("dataset1.xlsx", logger=logger)
migration = load_mapper("mapper.xlsx", logger=logger)
output_success, output_failed = init_outputs(migration)

# Pre-flight: column presence, mapping coverage, date format
run_preflight_checks(
    data,
    migration,
    date_columns=["Datevalue", "Datevalue"],
    date_format="%d.%m.%Y",
    logger=logger,
)

# ... your conversion loop ...

# Post-conversion checks
check_output_date_formats(output_success, date_format="%d.%m.%Y", logger=logger)
run_date_correlation_check(output_success, logger=logger)

# Write outputs and summary
output_zucc, output_fail = write_outputs(output_success, output_failed, "dataset1", logger)
print_summary(len(data), len(output_success), len(output_failed), output_zucc, output_fail, 12.4, logger)

# Generate HTML report
generate_html_report(
    dataset_name="dataset1",
    total_rows=len(data),
    success_count=len(output_success),
    failed_count=len(output_failed),
    execution_time=12.4,
    output_success=output_success,
    output_failed=output_failed,
    logger=logger,
)

CLI

# Run preflight checks only
migration-tools validate --dataset dataset1.xlsx --mapper mapper.xlsx

# Validate and generate an HTML report
migration-tools report --dataset dataset1.xlsx --mapper mapper.xlsx --format html

# Validate and generate an Excel report
migration-tools report --dataset dataset1.xlsx --mapper mapper.xlsx --format excel

# Both formats at once
migration-tools report --dataset dataset1.xlsx --mapper mapper.xlsx --format both

# Custom date columns and format
migration-tools validate \
    --dataset dataset1.xlsx \
    --mapper mapper.xlsx \
    --date-cols PaatosPaiva VoimassaolonAlkamisPaiva \
    --date-format "%d.%m.%Y"

Supported file formats

File	Formats supported
Dataset	.xlsx, .csv, .json
Mapper	.xlsx, .json

What gets validated

Check	When
Required columns present in dataset	Pre-flight
Mapping coverage (all value combos have a mapper row)	Pre-flight
Source date format	Pre-flight
Near-duplicate / whitespace column names	Pre-flight
Output date format after transformation	Post-conversion
Decision_FromDate ≤ Decision_ToDate	Post-conversion
Actualization_Date matches Decision_FromDate	Post-conversion

Publishing a new version

1. Bump version in pyproject.toml and __init__.py
2. Commit and push to main
3. Create a GitHub Release — CI will build and publish to PyPI automatically

Development

git clone https://github.com/yourname/migration-tools
cd migration-tools
pip install -e ".[dev]"
pytest tests/ -v --cov=migration_tools
