What differs for Google Sheets

For letters built from Google Sheets data, the lowest paid starting price is $5 a month after conversion to dollars, from Docs Creator. Published starting prices run from $5 to $39 a month, the top end from MailMergic. Google Sheets has no built-in document generation; Apps Script can merge rows into Google Docs if you write the code.

These tools for letters most often write PDF (8), email (7) and Google Docs (5). Among them, 1 needs Zapier, Make or n8n to read Google Sheets data, so it sits after the tools with a direct connection. Add-ons run from the Extensions menu or on a schedule, and Apps Script can run on edit or on a time trigger. Prices were checked on 20 Oct 2026.
