AI Form Filler

📅 Support for Multiple Date Formats: Generates dates of birth in formats (`dd/mm/yyyy`, `yyyy-mm-dd`, `dd-mm-yyyy`, ISO UTC) and adapts to `<input type="date">`.

☑️ Checkbox Handling: Detects and programmatically checks or unchecks boxes.

🇬🇧 UK-Specific Data: Produces realistic UK banking details, National Insurance numbers, tax codes, and postcodes.

⚙️ Customizable Filling: Allows individual or bulk filling with options for formats or checked states.

1️⃣ Custom Faker Extensions

Enhancements to faker.js include:

🎩 Titles (`Mr`, `Mrs`) 🚻 Gender (`Male`, `Female`) 💳 UK banking details (account, sort code) 🧾 Tax details (NI number, tax code) 🎂 Dates of birth with format support 🏠 Postcodes 📧 Custom email addresses 🔢 Random numbers of specified digit length

2️⃣ Field Detection Logic

🔍 Detection: Finds all fields (excluding hidden inputs) using `querySelectorAll`. 🏷️ Label Extraction: Uses `label[for=]`, `aria-label`, placeholders, and DOM traversal. 🧩 Type Suggestion: Matches labels/names/IDs via regex to suggest faker methods.

3️⃣ Filling Logic

📝 Text Inputs & Text areas: Auto-fill based on detected type. 🔽 Selects: Matches data to options or selects randomly. 📅 Date Pickers: Adapts date formats automatically. ☑️ Checkboxes: Check/uncheck based on logic or randomness.
