Go Document Merge - Bulk personalized Google Docs
Go Document Merge is an automated document creation add-on for Google Workspace. Prepare merge data in Google Sheets, build a Google Docs template with {{Column Name}} variables, choose a Google Drive output folder path (which can include variables), and start the merger. It runs until documents are created, can resume hourly when quota is hit, and shows merge status in the sheet. Typical quotas cited on site are about 2000 docs/day for normal Gmail and about 4000/day for Google Workspace. The Marketplace listing describes it as 100% free. Built for teams that need bulk personalized contracts, letters, certificates, and other Google Docs without leaving Google Workspace. Pricing: Free, with daily quotas applying.
