Amplify Excel Migrator

A CLI tool to migrate data from Excel files to AWS Amplify GraphQL API. Developed for the MECO project - https://github.com/sworgkh/meco-observations-amplify

Installation

From PyPI (Recommended)

Install the latest stable version from PyPI:

pip install amplify-excel-migrator

From Source

Clone the repository and install:

git clone https://github.com/EyalPoly/amplify-excel-migrator.git
cd amplify-excel-migrator
pip install .

Usage

The tool has five subcommands:

1. Configure (First Time Setup)

Save your AWS Amplify configuration:

amplify-migrator config

This will prompt you for:

• Excel file path
• AWS Amplify API endpoint
• AWS Region
• Cognito User Pool ID
• Cognito Client ID
• Admin username

Configuration is saved to ~/.amplify-migrator/config.json

2. Show Configuration

View your current saved configuration:

amplify-migrator show

3. Export Schema

Export your GraphQL schema to a markdown reference document:

# Export all models
amplify-migrator export-schema

# Export to a specific file
amplify-migrator export-schema --output my-schema.md

# Export specific models only
amplify-migrator export-schema --models User Post Comment

This generates a comprehensive markdown document with:

• All model fields with types and requirements
• Enum definitions
• Custom type structures
• Foreign key relationships
• Excel formatting guidelines

Perfect for sharing with team members who need to prepare Excel files for migration.

💡 The exported schema reference can help you prepare your Excel file. For detailed formatting guidelines, see the Excel Format Specification.

4. Export Data

Export model records from your Amplify backend to an Excel file:

# Export a single model's records
amplify-migrator export-data --model Reporter

# Export multiple models (each as a separate sheet)
amplify-migrator export-data --model Reporter Article Comment

# Export all models
amplify-migrator export-data --all

# Export to a specific file
amplify-migrator export-data --model Reporter --output reporter_backup.xlsx
amplify-migrator export-data --all --output full_backup.xlsx

Records are sorted by primary field and exported with scalar, enum, and ID fields. When exporting multiple models, each model gets its own sheet in the Excel file. This is useful for backing up data, auditing records, or preparing corrections for re-migration.

5. Run Migration

Run the migration using your saved configuration:

amplify-migrator migrate

You'll only be prompted for your password (for security, passwords are never cached).

Quick Start

# First time: configure the tool
amplify-migrator config

# View current configuration
amplify-migrator show

# Export schema documentation (share with team)
amplify-migrator export-schema

# Export existing records to Excel
amplify-migrator export-data --model Reporter
amplify-migrator export-data --all

# Run migration (uses saved config)
amplify-migrator migrate

# View help
amplify-migrator --help

📋 For detailed Excel format requirements, see the Excel Format Specification.

Requirements

• Python 3.8+
• AWS Amplify GraphQL API
• AWS Cognito User Pool
• Admin access to the Cognito User Pool

Features

Data Processing & Conversion

• Automatic type parsing - Smart field type detection for all GraphQL types including scalars, enums, and custom types
• Custom types and enums - Full support for Amplify custom types with automatic conversion
• Duplicate detection - Automatically skips existing records to prevent duplicates
• Foreign key resolution - Automatic relationship handling with pre-fetching for performance

AWS Integration

• Configuration caching - Save your setup, reuse it for multiple migrations
• MFA support - Works with multi-factor authentication
• Admin group validation - Ensures proper authorization before migration

Performance

• Async uploads - Fast parallel uploads with configurable batch size
• Connection pooling - Efficient HTTP connection reuse for better performance
• Pagination support - Handles large datasets efficiently

User Experience

• Interactive prompts - Easy step-by-step configuration
• Progress reporting - Real-time feedback on migration status
• Detailed error messages - Clear context for troubleshooting failures
• Schema export - Generate markdown documentation of your GraphQL schema to share with team members
• Data export - Export existing model records to Excel for backup, auditing, or correction

Excel Format Requirements

Your Excel file must follow specific formatting guidelines for sheet names, column headers, data types, and special field handling. For comprehensive format requirements, examples, and troubleshooting, see:

📋 Excel Format Specification Guide

Advanced Features

• Foreign Key Resolution - Automatically resolves relationships between models with pre-fetching for optimal performance
• Schema Introspection - Dynamically queries your GraphQL schema to understand model structures and field types
• Configurable Batch Processing - Tune upload performance with adjustable batch sizes (default: 20 records per batch)
• Progress Reporting - Real-time batch progress with per-sheet confirmation prompts before upload

Error Handling & Recovery

When records fail to upload, the tool provides a robust recovery mechanism to help you identify and fix issues without starting over.

How It Works

1. Automatic Error Capture - Each failed record is logged with detailed error messages explaining what went wrong
2. Failed Records Export - After migration completes, you'll be prompted to export failed records to a new Excel file with a timestamp (e.g., data_failed_records_20251201_143022.xlsx)
3. Easy Retry - Fix the issues in the exported file and run the migration again using only the failed records
4. Progress Visibility - Detailed summary shows success/failure counts, percentages, and specific error reasons for each failed record

The tool tracks which records succeeded and failed, providing row-level context to help you quickly identify and resolve issues. Simply export the failed records, fix the errors in the Excel file, and re-run the migration with the corrected file.

Troubleshooting

Authentication & AWS Configuration

Authentication Errors:

• Verify your Cognito User Pool ID and Client ID are correct
• Ensure your username and password are valid
• Check that your user is in the ADMINS group

MFA Issues:

• Enable MFA in your Cognito User Pool settings if required
• Ensure your user has MFA set up (SMS or software token)

AWS Credentials:

• Set up AWS credentials in ~/.aws/credentials
• Or set environment variables: AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_DEFAULT_REGION
• Or use aws configure to set up your default profile

Permission Errors:

• Add your user to the ADMINS group in Cognito User Pool
• Contact your AWS administrator if you don't have permission
