Address Formatter Guide
The Address Formatter tool helps you standardize and validate postal addresses using country-specific formatting rules. It supports both single address processing and bulk operations, with options for structured input, freeform parsing, and various export formats.
Single Address Mode
In single mode, you can format one address at a time. Choose between structured fields or paste a freeform address block.
Structured Input
Fill in the individual fields for recipient, organization, house number, street, address lines, locality, administrative area, and postal code. The tool dynamically adjusts labels based on the selected country (e.g., "State" for US, "Province" for CA).
Example (US):
- Recipient: John Doe
- Organization: Acme Inc.
- House Number: 123
- Street: Main St
- Address Line 2: Apt 4B
- Locality: San Francisco
- Administrative Area: CA
- Postal Code: 94107
Formatted (International):
John Doe
Acme Inc.
123 Main St Apt 4B
San Francisco, CA 94107
United States
Freeform Input
Paste a multi-line address, and the tool will attempt to parse it into structured fields based on the selected country. Click "Parse" to extract components.
Example Input:
John Doe
Acme Inc.
123 Main St Apt 4B
San Francisco, CA 94107
United States
Country Selection
Choose from supported countries including US, Canada, UK, Germany, France, India, Australia, and Japan. Each has unique postal code validation and formatting templates.
Example (UK):
Formatted: Mr John Smith
BBC Broadcasting House
Portland Place
London W1A 1AA
United Kingdom
Formatting Styles
- International: Multi-line format suitable for envelopes.
- National: Local format variation (e.g., different line order).

Options

- Line endings: LF (\n) or CRLF (\r\n).

Validation
The tool validates required fields and postal code formats per country. Issues are displayed below the actions.
Actions
