Auto Capitalize & UPPERCASE Names and Addresses ensures all customer names and addresses in your WordPress and WooCommerce site are properly formatted, maintaining professional consistency across your entire platform.

The Problem It Solves

Many website owners face issues with inconsistent name and address formatting:

Customers entering names and addresses in all lowercase during registration or checkout
Unprofessional-looking reports and invoices with incorrect capitalization
Billing errors and disputes due to mismatched name formats
Poor data quality affecting marketing efforts and customer communications
Manual correction of thousands of existing records
Need for specific fields in UPPERCASE for legal or formatting requirements
Business acronyms and brand names being incorrectly formatted

This plugin was born from a real client need: ensuring invoice reports had correctly formatted names and addresses to avoid billing discrepancies and maintain professional standards.

Exclusions Feature (NEW in 2.1.0)

The plugin allows you to define terms that should not be modified during formatting. This works with exact matching – the plugin will preserve the term exactly as you write it in the exclusion list.

Two Independent Exclusion Lists:
– Main Settings: For automatic formatting of new/edited records
– Bulk Tool: Separate list for one-time bulk conversions

Examples:
* Particles: de, la, del (for “Juan de la Cruz”)
* Spanish business types: SL, S.L., SA, S.A., SLU
* Acronyms: CCOO, UGT, ONU, UNESCO, UNED
* Brand names: iPhone, WordPress, PayPal
* Multiple variants: If you want to cover all cases, add each variant: de, De, DE

How it works:
If “SL” is in your exclusion list, only the exact text “SL” will be preserved. If the input contains “sl” or “Sl”, those will be formatted according to the selected mode. To preserve all variants, add them all: sl, SL, Sl, s.l., S.L.

Bulk Conversion Tool

The bulk conversion tool is completely independent from automatic formatting settings:

Three Conversion Modes:
1. Capitalize: Names capitalized respecting particles, addresses capitalized, emails/phones to lowercase
2. UPPERCASE: All selected fields converted to UPPERCASE
3. lowercase: All selected fields converted to lowercase (useful to undo incorrect changes)

Detailed Selection:
– WordPress user first and last names
– Customer billing and shipping names
– Complete customer addresses (billing and shipping)
– Order billing and shipping names
– Complete order addresses (billing and shipping)
– Additional fields (email, phone, etc.)

Independent Exclusions:
The bulk tool has its own exclusion list, separate from automatic formatting settings. This allows you to have different exclusion rules for bulk conversions.
