What PlainMerge is
PlainMerge creates personalized PDF files by combining a PDF template with rows from Excel-compatible spreadsheets. Users can drag spreadsheet headers onto template positions or connect them to native PDF form fields. The application supports native forms, custom fonts, multi-page documents, and QR code rendering. Input formats include .xlsx, .xls, and .ods. Outputs can be batches of personalized PDFs, emails carrying PDF attachments, or both. The desktop application works offline on macOS, Windows, and Linux. The maker also links to Mergram, a browser service for merging PDFs without installation. PlainMerge is described as open source, and its GitHub repository displays an AGPL-3.0 license. The paid plan costs $59, paid once as a one-time fee for those desktop platforms. There is no free plan, but a personal-use trial is available. Support is offered through email and GitHub Discussions. The privacy policy says support-submitted personal information may be retained indefinitely, including in backups, and purchases are not refundable.
