A Python ETL package that synchronizes data from SQL databases to Google Sheets using Service Account authentication. Supports MySQL, PostgreSQL, SQLite, and SQL Server with four access interfaces: CLI, REST API, Web Dashboard, and Desktop Application.

**Version:** 1.0.0 | **Python:** 3.10-3.12+ | **License:** MIT

## Features

- **Multi-database support** — MySQL, PostgreSQL, SQLite, SQL Server
- **Multiple sync modes** — full replace, append, and streaming (chunked) for large datasets
- **Interactive setup wizard** — `quickstart` command walks through first-time configuration
- **Demo mode** — try it without a real database (`--demo`)
- **REST API** (FastAPI) with OpenAPI docs at `/docs`
- **Web Dashboard** (Flask) for browser-based sync management
- **Built-in scheduler** — cron-based scheduling with APScheduler
- **Column mapping** — rename, reorder, and filter columns
- **Preview & dry-run** — see diffs before applying changes
- **Snapshots & rollback** — restore previous sheet states
- **Incremental sync** — timestamp-based change detection
- **Job queue** — async job processing with SQLite or Redis backends
- **Freshness/SLA monitoring** — track data staleness with alerts
- **Multi-tenant** — organizations, users, RBAC (owner/admin/operator/viewer)
- **Notifications** — email, Slack, and webhook backends
- **Prometheus metrics** — built-in metrics endpoint
- **Subscription tiers** — FREE, PRO, BUSINESS, ENTERPRISE with usage metering
- **RS256 license keys** — offline-validated JWT license keys

```

## Getting Started

### Try It First (No Setup Required)

```bash
pip install mysql-to-sheets
mysql-to-sheets sync --demo
```

This runs a sample sync with built-in demo data. See [Demo Mode](docs/demo.md) for details.

### Full Setup

Ready to sync real data:

#### Step 1: Install

```bash
pip install mysql-to-sheets
```

#### Step 2: Set Up Google Cloud

1. Create a service account: [Google Cloud Console](https://console.cloud.google.com/iam-admin/serviceaccounts)
2. Download JSON key as `service_account.json`
3. Enable Google Sheets API: [Enable API](https://console.cloud.google.com/apis/library/sheets.googleapis.com)

[Detailed Setup Guide](docs/google-cloud-setup.md)

#### Step 3: Configure

```bash
mysql-to-sheets quickstart
```

Or create `.env` manually:

```bash
DB_HOST=localhost
DB_USER=readonly_user
DB_PASSWORD=secret
DB_NAME=mydb
SQL_QUERY=SELECT * FROM users LIMIT 1000
GOOGLE_SHEET_ID=your_spreadsheet_id
SERVICE_ACCOUNT_FILE=./service_account.json
```

#### Step 4: Sync

```bash
# Preview changes first
mysql-to-sheets sync --dry-run

# Run the sync
mysql-to-sheets sync
```

### Troubleshooting

If something goes wrong:

```bash
mysql-to-sheets diagnose
```

[Troubleshooting Guide](docs/troubleshooting.md)

### Optional Dependencies

```bash
pip install mysql-to-sheets[postgres]   # PostgreSQL support
pip install mysql-to-sheets[mssql]      # SQL Server support
pip install mysql-to-sheets[redis]      # Redis job queue backend
pip install mysql-to-sheets[desktop]    # Desktop app dependencies
pip install mysql-to-sheets[all]        # All optional drivers
```

### Try Without Setup

Demo mode requires no database or Google Sheets:

```bash
mysql-to-sheets sync --demo
```

### Development Install

```bash
git clone https://github.com/BrandonFricke/mysql-to-sheets.git
cd mysql-to-sheets
pip install -e ".[dev]"
```

## Desktop Installation

Download the installer for your platform from [GitHub Releases](https://github.com/BrandonFricke/mysql-to-sheets/releases).

### macOS

1. Download `mysql-to-sheets-X.X.X-macos.dmg`
2. Open the DMG and drag "MySQL to Sheets Sync" to Applications
3. On first launch, you may see a security warning (app is not notarized)

**Bypassing macOS Gatekeeper:**
1. Right-click (or Ctrl+click) the app in Applications
2. Select "Open" from the context menu
3. Click "Open" in the dialog
4. The app will launch and be remembered for future launches

### Windows

1. Download `mysql-to-sheets-X.X.X-windows-setup.exe`
2. Run the installer — it will create Start Menu shortcuts
3. On first launch, you may see a SmartScreen warning (app is not code-signed)

**Bypassing Windows SmartScreen:**
1. Click "More info" on the warning dialog
2. Click "Run anyway"
3. The app will launch normally after this

### Linux

1. Download `mysql-to-sheets-X.X.X-x86_64.AppImage`
2. Make it executable: `chmod +x mysql-to-sheets-*.AppImage`
3. Run it: `./mysql-to-sheets-*.AppImage`

No installation needed — AppImage is a portable format.

### Auto-Updates

The desktop app checks for updates automatically once per day. You can also check manually via the system tray menu: **Check for Updates...**

When an update is available, you'll see a notification and a menu item to download it.

## Google Cloud Setup

1. Create a project in [Google Cloud Console](https://console.cloud.google.com/)
2. Enable the **Google Sheets API** (APIs & Services > Library)
3. Create a **Service Account** (APIs & Services > Credentials > Create Credentials)
4. Download the JSON key and save as `service_account.json`
5. Find the `client_email` in the JSON file
6. **Share** your Google Sheet with that email as **Editor**

For detailed instructions, common mistakes, and troubleshooting, see the [Google Cloud Setup Guide](docs/google-cloud-setup.md).

## Security Notes

- Never commit `.env` or `service_account.json` to version control (already in `.gitignore`)
- Create a database user with SELECT-only permissions for sync operations
- SQL validation is enabled by default (blocks DROP, DELETE, etc.)
- API authentication is enabled by default
- Account lockout after 5 failed login attempts
- RBAC uses fail-closed design — unknown permissions are denied
- Webhook deliveries are signed with HMAC-SHA256

## Troubleshooting

| Error | Cause | Solution |
|-------|-------|----------|
| "Spreadsheet not found" | Sheet ID incorrect or not shared | Verify ID and share with service account email |
| "Connection refused" | Database not accessible | Check host, port, firewall rules |
| "Service account file not found" | Missing credentials | Download JSON from Google Cloud Console |
| "Worksheet not found" | Tab name mismatch | Check `GOOGLE_WORKSHEET_NAME` |
| "UnsupportedDatabaseError" | Invalid `DB_TYPE` | Use `mysql`, `postgres`, `sqlite`, or `mssql` |
| "ModuleNotFoundError: psycopg2" | PostgreSQL driver missing | `pip install mysql-to-sheets[postgres]` |

Run full diagnostics:

```bash
python -m mysql_to_sheets diagnose
```

## Roadmap

- [PRIORITIES.md](PRIORITIES.md) — Market-readiness priorities (ship blockers → growth)
- [ROADMAP.md](ROADMAP.md) — Completed development phases and future items
- [STANDALONE_PROJECTS.md](STANDALONE_PROJECTS.md) — Extractable packages and standalone services
