Main functions
- User Login/Logout
- Load Data
- Auto Fill
Basic Usage
- Navigate to a webpage with a form you want to fill out
- Click the FormMasterPro icon in your browser toolbar
- Login with your gmail accont, or creat an account.
- Click "Load Data File" to import data from a single file, or "Load Folder" (premium subscribers only) to import data from multiple files
- Click "Auto Fill Form" to automatically populate the form fields. This button is also on the bottom left pop up menu
Supported File Formats
- DOCX: Microsoft Word documents
- PDF: Portable Document Format files
Creating Data Files
FormMasterPro can extract data from different file formats to populate HTML forms on websites. Here's how to prepare them:
DOCX Documents
FormMasterPro can extract data from structured DOCX documents, including:
- Regular paragraphs of text
- Tables with labeled rows and columns
- Formatted sections with headings
The extension will attempt to intelligently parse the document structure and extract relevant information.
PDF Documents
FormMasterPro can extract data from PDF files, including:
- Text content from all pages
- Form fields and their values
- Tables and structured content
For best results, ensure your PDF contains selectable text rather than scanned images.
Note: While FormMasterPro extracts data from PDF files, it cannot fill out PDF forms directly. It uses the extracted data to fill HTML forms on websites.
Loading Data from Folders Premium
Note: This feature is only available for premium subscribers.
FormMasterPro offers premium subscribers the ability to load multiple files at once from a folder:
- Click "Load Folder" and select a folder containing your documents
- All supported files (PDF and DOCX) in the folder will be loaded into memory
- The extension merges information from all files to create a comprehensive data source
- This is especially useful when your information is spread across multiple documents
When using folder extraction:
- Organize related documents in a single folder
- Consider file naming to ensure logical processing order (e.g., "01_personal.pdf", "02_education.docx")
- Be mindful of memory usage when loading many large files
- The AI will attempt to resolve any conflicting information across documents
Pro Tip
For complex applications, organize your documents by category in a single folder. For example, have one document for personal details, another for educational history, and another for employment records.

Upgrade NowImportance of Quality Input for AI
The effectiveness of FormMasterPro's AI-powered form filling depends significantly on the quality of your input data:
Why Quality Matters
- Accuracy: Higher quality inputs result in more accurate form filling
- Efficiency: Well-structured data reduces the need for manual corrections
- Consistency: Clean data leads to consistent results across multiple forms
- Recognition: Clear formatting helps the AI better recognize data patterns
Tips for Optimal AI Input
- Use consistent formatting in your source documents
- Label data clearly with descriptive field names
- Structure information hierarchically (e.g., personal information, address, education)
- Avoid abbreviations when possible, or use standard ones
- Ensure text is machine-readable (not embedded in images)
- Check for typos and formatting errors before importing
Example Comparison
Poor Quality Input | High Quality Input |
---|---|
John doe, johnd@email 555-1234 |
Name: John Doe Email: john.doe@example.com Phone: (555) 123-4567 |
addr: 123 main st anytown |
Address: 123 Main Street City: Anytown State/Province: California Postal Code: 12345 |
Impact on Form Filling
When FormMasterPro processes high-quality inputs:
- Field matching becomes more precise
- The need for manual mapping is reduced
- Complex forms can be filled with greater confidence
- The system learns more effectively from each interaction
Pro Tip
For best results, organize your data in a way that mirrors how it would appear on a form. This helps the AI understand the context and relationship between different pieces of information.
Field Mapping
Sometimes, you may need to manually map data fields to form fields:
- Click "Data Mappings" in the extension popup
- Use the mapping interface to connect your data fields with form fields
- Save your mappings for future use
FormMasterPro will remember your mappings for each website, making future form filling even faster.
Limitations
While FormMasterPro is a powerful tool, it's important to understand its current limitations:
- HTML Forms Only: FormMasterPro works exclusively with HTML forms on websites. It cannot fill out PDF forms, desktop application forms, or other document-based forms.
- Data Extraction vs Form Filling: The extension extracts data FROM PDFs and DOCX files, but it fills data INTO HTML web forms only.
- Complex Dynamic Forms: Some highly complex JavaScript-based forms with unusual implementations may present challenges.
- Anti-Automation Sites: Websites with strong anti-automation measures may block or limit FormMasterPro's functionality.
- Image-Based PDFs: PDFs containing scanned images without proper OCR text layers may have limited data extraction.
We're continuously working to improve FormMasterPro's capabilities and overcome these limitations in future updates.
Frequently Asked Questions
What types of forms can FormMasterPro fill?
FormMasterPro can fill almost any HTML-based web form including job applications, account registrations, contact forms, surveys, and more. It works best with clearly labeled form fields that match common data patterns.
Is my data secure when using FormMasterPro?
Yes. FormMasterPro processes your data locally in your browser. Your sensitive information never leaves your computer unless you specifically submit a form. We don't store or access your personal data on our servers.
How accurate is the AI form filling?
FormMasterPro achieves high accuracy rates (typically 85-95%) on most standard forms. The accuracy depends on the quality of your input data and the complexity of the form. Well-structured input documents and clearly labeled form fields yield the best results.
