About the Mail Merge Tool
The Mail Merge Tool combines a text template with rows of CSV data to produce personalized documents — one per row — entirely in your browser. Write your message once with placeholders, supply a spreadsheet of names and details, and generate a customized version for every recipient.
Personalized communication at scale usually means clunky office software or a paid service. This tool gives you the core of mail merge for free and private: certificates, letters, notices, and emails that address each person by name and fill in their specific details.
Because it runs client-side, your template and recipient data never leave your device. That’s important when the spreadsheet holds names, addresses, or other personal information — nothing is uploaded, and no account is required.
How to use the Mail Merge Tool
- Write or paste your template, using placeholders for the fields to personalize.
- Upload the CSV containing one row per recipient.
- Map the placeholders to the matching CSV columns.
- Preview a generated example to confirm the merge looks right.
- Generate the personalized documents for every row.
- Copy or download the results.
Common use cases
- Producing personalized certificates for a group of participants.
- Generating individualized letters or notices from a contact list.
- Creating customized emails that greet each recipient by name.
- Filling a repeated template with details from a spreadsheet.
Frequently asked questions
How do placeholders work?
You insert a placeholder for each field you want personalized, then map those placeholders to columns in your CSV. Each row’s values are substituted to create a unique document.
What format does my data need to be in?
A CSV with a header row works best, where each column is a field and each row is one recipient or document.
Does it send emails for me?
It generates the personalized content; sending is up to you. You can copy the output into your email client or save the documents.
Is my recipient data uploaded to a server?
No. Both the template and the CSV are processed in your browser, so personal data never leaves your device.
How is this different from the Batch PDF Form Filler?
Mail merge fills a text template to produce documents or messages, while the Batch PDF Form Filler populates fields in an existing fillable PDF. Choose based on whether you start from text or a PDF form.
