+# LittleShop Product Import - Complete Guide
+
+## Summary of Changes
+
+### 1. **CSV File Created** ✅
+- **Location**: `/mnt/c/Production/Source/LittleShop/products_import.csv`
+- **Products**: 13 products with full variant pricing
+- **Categories**: 4 categories (Flour, Cereal, Vitamins, Herbal) - will be auto-created during import
+- **Format**: Proper CSV format with all required columns
+
+### 2. **Replace All Functionality Added** ✅
+- **Feature**: New "Replace All" checkbox in the import UI
+- **Location**: Admin Panel → Products → Import
+- **Functionality**: When checked, deletes ALL existing products, variants, and categories before import
+- **Warning**: Displays prominent warning message about data deletion
+
+### 3. **Auto-Create Categories** ✅
+- **Feature**: Categories are automatically created during import if they don't exist
+- **Benefit**: No need to manually create categories before importing
+- **Logging**: Auto-creation is logged for audit purposes
+
+### 4. **Unit Type Clarification** ✅
+- **Note**: The existing `Unit` enum value (0) serves as "Single" for individual items
+- **Usage**: Used for tablets/capsules where quantity is measured in units rather than weight
+- **No Changes Made**: Enum remains unchanged as `Unit` is already suitable
+

+## Import Instructions
+
+### Option 1: Replace All Products (Clean Slate)
+1. Navigate to **Admin Panel → Products → Import**
+2. **Check the "Replace All" checkbox** ⚠️ WARNING: This deletes all existing data!
+3. Click "Choose File" and select `products_import.csv`
+4. Click "Import Products"
+5. Review the import results
+
+### Option 2: Add to Existing Products
+1. Navigate to **Admin Panel → Products → Import**
+2. **Leave "Replace All" unchecked**
+3. Click "Choose File" and select `products_import.csv`
+4. Click "Import Products"
+5. Products will be added alongside existing products
+
+## Technical Implementation Details
+
+### Code Changes
+
+#### 1. ProductImportService.cs
+- **Interface Updated**: Added `replaceAll` parameter to import methods
+- **New Method**: `DeleteAllProductsAndCategoriesAsync()` - Removes all product data
+- **Auto-Create Categories**: Categories from CSV are created automatically if missing
+- **Enhanced Logging**: Warning logs when replace all is triggered
+
+#### 2. ProductsController.cs (Admin Area)
+- **Import Action Updated**: Now accepts `bool replaceAll` parameter
+- **Passes Parameter**: Forwards `replaceAll` to import service
+
+#### 3. Import.cshtml View
+- **New Checkbox**: "Replace All" option with danger styling
+- **Warning Message**: Prominent warning about data deletion
+- **User Experience**: Clear indication of destructive action
+
+### Database Operations (Replace All)
+The delete operation executes in this order:
+1. ProductPhotos
+2. ProductVariations (variants/multi-buys)
+3. ProductMultiBuys
+4. Products
+5. Categories
+
+## CSV Format Reference
+
+```csv
+Name,Description,Price,Weight,WeightUnit,StockQuantity,CategoryName,IsActive,Variations,PhotoUrls
+Product Name,Description text,29.99,100,Grams,50,Category Name,true,Name:Qty:Price;Name:Qty:Price,
+```
+
+### Variations Format
+```
+VariantName:Quantity:Price;VariantName:Quantity:Price
+Example: 28g:1:700;14g:1:360;7g:1:190
+```
+
+### Weight Units
+- `Grams` - For weight-based products
+- `Unit` - For individual items (tablets, capsules)
+- `Kilograms`, `Pounds`, `Ounces` - Also supported
+
+## Safety Features
+
+1. **Explicit Opt-In**: Replace All requires checkbox to be checked
+2. **Visual Warnings**: Red danger styling on checkbox and warning message
+3. **Audit Logging**: All deletions and auto-creations are logged
+4. **Transaction Safety**: Database operations use EF Core transactions
+5. **Error Reporting**: Detailed error messages for failed imports
+
+## Testing Recommendations
+
+### Before Production Use
+1. **Backup Database**: Always backup before using "Replace All"
+2. **Test Import**: Try importing without "Replace All" first
+3. **Verify Results**: Check all products, variants, and categories created correctly
+4. **Review Logs**: Check application logs for any warnings or errors
+
+### Post-Import Verification
+1. Navigate to **Products** page - verify product count
+2. Check **Categories** page - verify all 4 categories exist
+3. Open individual products - verify variants are created
+4. Test ordering workflow through TeleBot (if applicable)
+
+## Support & Troubleshooting
+
+### Common Issues
+
+**Issue**: Import fails with "Missing required column" error
+**Solution**: Ensure CSV has all required headers matching the template
+
+**Issue**: Categories not created
+**Solution**: Categories are auto-created - check application logs for confirmation
+
+**Issue**: Variants not showing
+**Solution**: Verify variation format matches `Name:Qty:Price;Name:Qty:Price`
+
+**Issue**: Price showing as 0
+**Solution**: Check CSV uses decimal format (e.g., `10.00` not `£10`)
+
+## File Locations
+
+- **CSV Import File**: `/mnt/c/Production/Source/LittleShop/products_import.csv`
+- **Import Service**: `LittleShop/Services/ProductImportService.cs`
+- **Controller**: `LittleShop/Areas/Admin/Controllers/ProductsController.cs`
+- **View**: `LittleShop/Areas/Admin/Views/Products/Import.cshtml`
+
+## Next Steps
+
+1. **Review CSV Data**: Verify product names, prices, and variants are correct
+2. **Backup Current Data**: If you have existing products, export them first
+3. **Import Products**: Use the Admin Panel to import the CSV
+4. **Test Integration**: Verify TeleBot can access and display products
+5. **Monitor Performance**: Check application logs for any issues
