SheetMergy is a document automation platform that generates personalized documents directly from Google Sheets data. It connects your spreadsheet to a template — built in Google Docs or uploaded as a DOCX file — and automatically produces invoices, certificates, reports, contracts, offer letters, and more in seconds. It works as both a web dashboard and a Google Workspace Add-on, requiring zero coding. Users set up a job once, and SheetMergy handles the rest — filtering the right rows, grouping data, generating documents, and emailing them to recipients automatically on any schedule. Unlike basic mail merge tools, SheetMergy supports multiple sheet tabs in one job, cross-tab filtering, data joins, custom header row selection, grouping by date or value, aggregated calculations, and full run history so you always know what generated and when. Used by real estate agencies, training companies, freelancers, HR teams, and small businesses — anyone who has data in Google Sheets and needs to turn it into professional documents without doing it manually one by one.
