How HR Can Generate 500 Onboarding Letters in 5 Minutes with Excel

The Scenario: Campus Hiring Season, 500 Onboarding Letters to Send

If you work in HR, you already know what’s coming. Campus recruiting season is here, and your director just dropped an Excel spreadsheet on your desk: 500 new hires, each with their name, department, position, start date, and salary. The request? “Get their onboarding letters done. EOD today.”

You open your Word template, copy a name from Excel, paste it in, save as a new file, change the next name, repeat. At a normal pace, one letter takes about 2 minutes (including proofreading). That’s 1,000 minutes — roughly 17 hours. Two full days of nonstop typing, assuming no breaks, no lunch, no life.

But there’s another way. It takes 5 minutes.

Step 1: Prepare a Word Template

Open a Word document and format it like your usual onboarding letter. The only difference: replace every variable piece with a placeholder wrapped in curly braces.

Dear {Name},

Congratulations on joining {Company}. We are pleased to offer you the position of {Position} in the {Department} department.

Start Date: {Start_Date}
Salary: {Salary}
Reporting To: {Manager}

Please bring your ID documents to {Office_Address} on your first day to complete the onboarding process.

Best regards,
{Company}
{Date}

This template takes about 15 minutes to set up — and then you can reuse it every year.

Step 2: Open Your Excel Data

Your Excel sheet looks like this:

Name Department Position Start_Date Salary Manager Office_Address
Zhang Wei Engineering Frontend Dev 2026-09-01 15000 Li Si Pudong Tower A
Li Li Marketing Operations 2026-09-03 12000 Wang Fang Pudong Tower B
… … … … … … …

Make sure the column headers match your {Placeholders} in the Word template.

Step 3: Open Sheet-to-Doc, Paste Data, Generate

Visit Sheet-to-Doc. Here’s the entire workflow:

  1. Upload your prepared Word template
  2. Copy and paste your Excel data into the website (or upload a CSV/Excel file)
  3. Set the filename rule to Onboarding_Letter_{Name}.docx
  4. Click “Generate”

Within seconds, your browser downloads a ZIP archive. Unzip it, and you’ll find 500 individual Word files — each named after the employee, each with the correct personal information filled in.

From opening the website to having the files ready: under 5 minutes.

Data Security: Why HR Can Trust This

HR data is among the most sensitive in any organization — salaries, ID numbers, home addresses. A single leak can mean serious compliance issues.

Sheet-to-Doc processes everything locally in your browser:

  • Data is never uploaded to any server
  • All processing happens on your own computer
  • Data is cleared immediately after processing

This means even your most sensitive payroll data never leaves your machine. For an extra layer of security, you can use the offline desktop version, which runs completely without internet access.

Beyond Onboarding: What Else Can HR Automate?

Onboarding letters are just the beginning. Here’s a list of HR document types that Sheet-to-Doc handles with ease:

Document Type Data Source Template Placeholders
Termination Certificate Departure Register {Name} {Departure_Date} {Position}
Salary Confirmation Payroll Sheet {Name} {Monthly_Salary} {Social_Insurance} {Housing_Fund}
Training Notice Training Roster {Name} {Training_Date} {Training_Location} {Course}
Transfer Notification Transfer Approval {Name} {Old_Position} {New_Position} {Effective_Date}
Bonus Letter Bonus Calculation {Name} {Bonus_Amount} {Payment_Date} {Tax}
Contract Attachment Contract Data {Name} {Contract_Term} {Salary} {Job_Description}

One template framework, reused all year round. Swap in a new Excel file each time — a batch of documents in minutes.

Is the Free Version Enough?

The free version of Sheet-to-Doc supports up to 10 rows per batch. If you process small batches monthly — say a few dozen people — the free version will likely cover you.

But if you’re generating 500 onboarding letters for campus recruiting, or hundreds of salary confirmations every pay cycle, the Pro version is the way to go. No row limits, plus access to encryption, loop placeholders, and other advanced features.

Final Thoughts

HR work shouldn’t be defined by endless copy-pasting. When you first cut 500 onboarding letters from 17 hours down to 5 minutes, you’ll realize — all that time you’ve been wasting could be spent on the things that actually matter.
