A CLI tool to migrate Excel data to AWS Amplify

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 three 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. 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

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

# View help
amplify-migrator --help

Example: Configuration

║        Amplify Migrator - Configuration Setup      ║
╚════════════════════════════════════════════════════╝

📋 Configuration Setup:
------------------------------------------------------
Excel file path [data.xlsx]: my-data.xlsx
AWS Amplify API endpoint: https://xxx.appsync-api.us-east-1.amazonaws.com/graphql
AWS Region [us-east-1]:

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

Excel File Format

The Excel file should have:

• One sheet per Amplify model (sheet name must match model name)
• Column names matching the model field names
• First row as headers

Basic Structure

Sheet: User

name	email	age
John	[e-mail]	30
Jane	[e-mail]	25

Sheet: Post

title	content	userId
First Post	Hello World	[e-mail]

Relationships (Foreign Keys)

To reference related records, use the primary key value of the related model:

Sheet: Comment

content	postId	userId
Great post!	post-123	[e-mail]

The tool automatically resolves foreign keys by looking up the related records.

Array/List Fields

Array fields support multiple input formats:

• JSON format: ["tag1", "tag2", "tag3"]
• Semicolon-separated: tag1; tag2; tag3
• Comma-separated: tag1, tag2, tag3

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

Recovery Workflow Example

# Run initial migration
amplify-migrator migrate

# Migration completes with some failures:
# ✅ Successfully uploaded: 95 records (95%)
# ❌ Failed to upload: 5 records (5%)
#
# Export failed records? (y/n): y
# Failed records exported to: data_failed_records_20251201_143022.xlsx

# Fix the errors in the exported Excel file
# Then re-run migration with the failed records file

amplify-migrator migrate
# Excel file path: data_failed_records_20251201_143022.xlsx

The tool tracks which records succeeded and failed, providing row-level context to help you quickly identify and resolve issues.

Troubleshooting

Authentication Errors

Error: Unable to authenticate with Cognito

• 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

Error: MFA required but not configured

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

AWS Credentials

Error: AWS credentials not found

• 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

Excel File Format

Error: Sheet name does not match any model

• Ensure sheet names exactly match your Amplify GraphQL model names (case-sensitive)
• Check for extra spaces or special characters in sheet names

Error: Required field missing

• Verify all required fields in your GraphQL schema have corresponding columns in Excel
• Check column names match field names (case-sensitive)

Permission Errors

Error: User is not in ADMINS group

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