How to fill multiple PDF forms from Excel
Keep the original PDF layout. Put column names in the first spreadsheet row and one customer, employee, vendor, or case in each row below it. JustFill creates a separate PDF for every selected row.
- 1
Upload the original PDF
Use an AcroForm, a flat PDF, or a scan. JustFill detects the fields before the merge.
- 2
Import XLSX or CSV
Dates, leading zeros, percentages, booleans, and spreadsheet headers are preserved for mapping.
- 3
Check the column mapping
Matching headers map directly. Ambiguous columns can use AI-assisted mapping.
- 4
Review and export
Approve the records you want and download individual filled PDFs in one ZIP.

Where it fits

Guardrails
Draft preparation with human review.
Clear boundaries
JustFill prepares PDF drafts from data your organization provides. It does not complete employee attestations, inspect identity or employment authorization documents, sign Section 1 or Section 2, or submit cases to E-Verify.
Beyond manual uploads
Run the same PDF workflow from an AI agent or n8n.
The browser flow is the fastest way to validate a spreadsheet and PDF. Once the mapping works, the same JustFill account can expose PDF detection, filling, and saved templates through the hosted MCP endpoint.
Frequently asked questions
Does JustFill replace Section 1 employee attestation or Section 2 document inspection?
No. JustFill only places user-supplied text into a PDF draft to reduce repetitive typing (such as employer business name, address, start date, or authorized contact info). Employees and employers must still review, complete required attestations, inspect physical or approved documents, and sign in compliance with USCIS rules.
Can we use this for other new-hire onboarding PDFs in the same packet?
Yes. You can run the same employee roster CSV against Form W-4, state withholding forms, direct deposit authorizations, and company policy acknowledgments.
Does it connect to E-Verify?
No. JustFill is a standalone browser PDF preparation tool and does not transmit data to USCIS or E-Verify.
Does it work with scanned or flat PDFs?
Yes. JustFill detects field locations in fillable, flat, and scanned PDFs before mapping spreadsheet columns.
Does each spreadsheet row create a separate PDF?
Yes. The first row contains the Excel or CSV column names. Every selected data row becomes one reviewable PDF in the exported ZIP.
Is this the same as Word mail merge?
It uses the same one-row-per-document idea, but fills your existing PDF directly. You do not need to recreate the form in Word or convert the PDF first.
Can I review results before downloading?
Yes. Each spreadsheet row becomes a reviewable record. Approve the records you want before creating the ZIP.
Does JustFill email the generated PDFs?
Not in the current self-service batch. It creates individual PDFs and packages the approved files in a ZIP for download.
What happens to uploaded documents?
Transfers use TLS. Rendered page images are deleted within 7 days and source documents within 30 days unless you save the PDF as a reusable template.
