Template-Based Reusability

Configure your field mappings once and save the setup for future use. This creates a powerful, reusable workflow that any team member can execute. When a new batch of data arrives, simply upload the new spreadsheet to the saved template flow and generate the filled PDFs instantly. This promotes consistency across all documents and empowers every team member to execute complex form filling without specialized training, fostering a truly cooperative and efficient work environment.

Law firms and real estate agencies can quickly assemble high volumes of standardized legal documents, such as rental agreements, client engagement letters, or property disclosure forms.

Frequently Asked Questions

Fill PDF from Excel FAQ

What file formats are supported for the PDF and data files?

We support fillable PDF forms as templates. For your data source, we accept Excel files (.xlsx and .xls), CSV files, and exports from Google Sheets. It is crucial that your PDF has properly defined, fillable form fields for our intelligent mapping system to detect and populate them correctly from your spreadsheet columns.

Do you store the files we upload for processing?

As a core feature focused on your security and privacy, we do not permanently store your uploaded PDF or data files. Uploaded files are processed in memory to generate your filled PDF results and are not retained on our servers after the processing session is complete, giving your team peace of mind when handling sensitive information.

How does the field mapping work?

When you upload your PDF form and data file, our system automatically scans the PDF for fillable fields and attempts to match them with column headers from your spreadsheet. You will be presented with a mapping screen to review these connections. Here, your team can manually link any unmatched fields or correct any suggestions, ensuring the automation aligns perfectly with your specific document structure.

Can I generate multiple PDFs from one data file?

Absolutely. This is the core of our batch processing capability. Each row in your Excel or CSV data file represents one unique set of information. When you run the process, the system will create a separate, individually filled PDF document for every row in your spreadsheet, making it ideal for teams that need to produce large volumes of personalized forms efficiently.
