Generate Document action in Zapier: mail merge Word templates into finished PDFs with PDF4me
· 15 min read
Generate Document is a PDF4me action for Zapier that performs a mail merge: it takes a Word, HTML or PDF template plus a JSON or XML data file and returns the filled document. A Zap can watch a folder, merge each record, and save every result without anyone opening Word.
Every mail merge tutorial you will find assumes a person is sitting in Word, clicking through a wizard. That works once. It does not work when a hundred invoices need generating on a schedule, or when the data arrives from a system rather than a spreadsheet on someone's desktop. This post covers the template syntax and the Zap that runs the merge unattended.
The flow at a glance

2. Find File
Dropbox fetches the Word template from its own folder.
3. Generate Document
PDF4me merges the data into the template.
4. Create Loop From Line Items
Only needed when the merge returns many documents.
5. Upload File
