What Does Address Normalizer Do?

This tool intelligently normalizes and fixes addresses using AI. It handles:

• Capitalization Fixes - Proper title case for street names, cities, and states
• Missing Fields - Fills in missing city, state, zip code, or country when possible
• Format Correction - Standardizes abbreviations and formats (St. → Street, Ave. → Avenue)
• Component Parsing - Breaks down addresses into structured components (street, city, state, zip, country)
• Bulk Processing - Process hundreds or thousands of addresses efficiently
• CSV Support - Upload CSV files with addresses for batch processing

Business Value: Save hours of manual address cleanup. Automatically standardize and fix address data, ensuring your database has clean, properly formatted addresses ready for mailing, analysis, or integration.

Input

To start normalizing addresses, simply fill in the input form. You can provide addresses in two ways:

• Addresses - List of addresses to normalize. Each address can be a string. The tool will parse and normalize each one.
• CSV File URL - Upload a CSV file containing addresses and provide the file URL. The CSV should have an 'address' column or columns for address components.
• Custom Prompt - (Optional) Custom instructions for address normalization. If not provided, default normalization rules will be used.

Here's what the filled-out input schema looks like:

And here it is written in JSON:

{
    "addresses": [
        "123 main st new york ny 10001",
        "456 oak avenue los angeles ca",
        "789 pine road chicago il 60601"
    ],
    "csvFileUrl": "",
    "customPrompt": ""
}

Pro Tip: Use CSV file upload for processing large batches of addresses. The tool will automatically detect the address column in your CSV.

Output

After the Actor finishes its run, you'll get a dataset with normalized addresses. Each address includes the original address, normalized address, and all address components. You can download those results as an Excel, HTML, XML, JSON, and CSV document.

Here's an example of normalized address data you'll get:

Example normalized address structure:

{
    "originalAddress": "123 main st new york ny 10001",
