## Admin Workflow Integration

### Current Workflow (Google Forms)
1. Parent fills Google Form
2. Data appears in Google Sheet automatically
3. Admin receives email notification
4. Admin reviews in spreadsheet

### New Workflow (AI Registration)
1. Parent converses with AI agent
2. Completed registration stored in system
3. Admin receives email notification (same as before)
4. Admin can:
   - View individual registrations in admin interface
   - Export to CSV for Google Sheets compatibility
   - Export to JSON for archival/backup

### Maintaining Google Sheets Compatibility

For admins who prefer working in Google Sheets:

**Option A: Manual Import**
1. Export CSV from the system
2. Import into Google Sheets (File → Import)
3. Work with data as before

**Option B: Direct Google Sheets Integration (Future)**
- Automatic sync to a designated Google Sheet
- Requires Google API setup
- *Note: This is a potential future enhancement, not initial release*

### Export Triggers

| Trigger | Action |
|---------|--------|
| Admin clicks "Export" | Generate CSV/JSON download |
| Scheduled (optional) | Auto-generate weekly export |
| API request (optional) | Return JSON for integrations |

### Data Consistency

- Exports always reflect current stored data
- Registration IDs are consistent across exports
- Timestamps are consistent (UTC internally, local time in exports)

## Filtering and Query Requirements

### Export Filters

When exporting data, the admin should be able to filter by:

| Filter | Options | Use Case |
|--------|---------|----------|
| Date range | From/To dates | "Show September registrations" |
| Playgroup type | Indoor / Outdoor / Both | "Export only forest playgroup kids" |
| Booking day | Monday / Wednesday / Thursday | "Who's coming on Wednesdays?" |
| Channel | Email / Chat | "How many registered via chat?" |

### Query Examples

**All registrations this month:**
```
dateFrom: 2024-09-01
dateTo: 2024-09-30
```

**Forest playgroup registrations:**
```
playgroupType: outdoor
```

**Monday attendees (both playgroups):**
```
bookingDay: monday
```

**Recent registrations via chat:**
```
dateFrom: 2024-09-15
channel: chat
```

### Combination Filters

Filters can be combined:
- "All outdoor registrations in September"
- "Monday indoor kids registered via email"

### Sort Options

| Sort by | Direction |
|---------|-----------|
| Submission date | Newest first (default) / Oldest first |
| Child name | A-Z / Z-A |
| Playgroup type | Indoor first / Outdoor first |

### Default Export Behavior

If no filters specified:
- All registrations
- Sorted by submission date (newest first)
- All fields included
