What potential pitfalls should be considered when automating the process of filling a webshop with product information from Excel?

One potential pitfall to consider when automating the process of filling a webshop with product information from Excel is data validation. It's important to ensure that the data being imported from Excel is formatted correctly and matches the expected data types in the webshop database to prevent errors and inconsistencies.

// Example data validation function
function validate_product_data($data) {
    // Check if required fields are present
    if (!isset($data['name']) || !isset($data['price']) || !isset($data['description'])) {
        return false;
    }
    
    // Validate data types
    if (!is_string($data['name']) || !is_numeric($data['price']) || !is_string($data['description'])) {
        return false;
    }
    
    // Additional validation logic as needed
    
    return true;
}
