22-second walkthrough
One PDF. Five spreadsheet rows. One ZIP.
A real production workflow with a synthetic vendor form and a five-row Excel workbook: match all nine fields, review every PDF, and export one ZIP.

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.
Sample input
One authorized worker row becomes one PDF
| Employee ID | Legal name | Start date |
|---|---|---|
| EMP-2041 | Alex Morgan | 2026-08-03 |
| EMP-2042 | Jordan Lee | 2026-08-10 |
| EMP-2043 | Taylor Kim | 2026-08-17 |
Upload the required PDF
Start with the current employer, agency, or client-specific form. Do not recreate it in Word.
Import authorized records
Use one worker or candidate per spreadsheet row and include only the fields required by the document.
Review before signature or delivery
Verify every field and record before the draft leaves your normal HR or compliance process.
Where it fits
Built for repeated paperwork—not hiring decisions.
Use JustFill after the correct candidate or employee data is already approved and the remaining work is placing it into recurring agency, employer, or client PDF layouts.
Simple pricing
Validate one onboarding form without scheduling a demo.
Try five synthetic sample rows first, then use your authorized data. Starter supports clean ZIPs of up to 25 records; Pro supports up to 100 records per batch.
Starter
Recommended first workflow
- Up to 25 PDFs per batch
- 125 clean output pages per month
- AI field detection for 25 new pages per month
- Clean, watermark-free ZIP exports
- CSV and XLSX spreadsheet imports
- Review every record before export
- Reusable reviewed PDF templates
Paid workflow
Reuse reviewed paperwork without turning JustFill into an HRIS.
Keep employee and candidate records in your approved source system. Use JustFill only to prepare the recurring PDF drafts that system does not produce.
Reusable form layout
Save reviewed field geometry for unchanged employer and client forms.
Minimal source columns
Pass only the approved fields required by the form instead of exporting an entire HR record.
Human-reviewed output
Inspect each generated draft and export selected PDFs for your existing approval process.
Guardrails
Draft preparation with human review.
Clear boundaries
JustFill does not screen candidates, verify identity or employment eligibility, provide HR or legal advice, sign forms, run E-Verify, or submit documents. It prepares drafts from authorized source data.
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 complete employment verification or E-Verify?
No. It can prepare a draft PDF from authorized data, but the employer and authorized representatives remain responsible for identity checks, required attestations, signatures, and submission.
Should we upload an entire HR export?
No. Create a minimal spreadsheet containing only the columns needed by the target PDF and only records you are authorized to process.
Can it handle client-specific staffing forms?
Yes. Upload the exact client form, review the detected fields, and save the layout for repeat batches while that PDF remains unchanged.
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.
