What differs for Excel

For letters built from Excel data, the lowest paid starting price is $6.58 a month, from Document Studio. Published starting prices run from $6.58 to $39 a month, the top end from MailMergic. Excel has no built-in document generation; Word mail merge can read rows from a workbook.

These tools for letters most often write PDF (5), DOCX (3) and XLSX (3). Among them, 1 needs Zapier, Make or n8n to read Excel data, so it sits after the tools with a direct connection. Generation runs from an add-in inside Excel, from an uploaded workbook, or from a Power Automate flow. Prices were checked on 20 Oct 2026.
