MailMergeOnline PDF mail merge from Excel
Merges an Excel sheet into hundreds of personalized PDFs, entirely in your browser.
MailMergeOnline binds a PDF template to rows from an Excel or CSV file and generates one PDF per row — offer letters, certificates, invoices, KYC packs — named from your own data and delivered as a zip. There's no upload step and no server: salary data, ID numbers and client records never leave the machine you're on. The 23 library templates are built from editable structured text rather than flattened artwork, so you can restyle or extend them instead of fighting a fixed layout.
What holds up
- +Nothing uploads to a server — salary and ID data in your spreadsheet never leaves your machine.
- +Generates one named PDF per row and bundles hundreds of them into a single zip.
- +23 templates are editable structured text, not flattened images, so you can restyle freely.
Mind the limits
- −No account means no sync across devices — everything lives in that one browser session.
- −Runs entirely client-side, so very large batches depend on your own machine's power.
