Personalize one message for a whole list. Paste (or load) a CSV whose first row is the column names, write a template using {{column}} placeholders, and Merge fills in a copy for every row. Preview them, print or save as PDF, or download them all as text files. Nothing is uploaded.

CSV data (first row = headings)

Template

The CSV parser understands quoted fields and commas inside quotes. Placeholders that don't match a column are left as-is so you can spot typos. "Print / PDF all" lays out one record per page — choose "Save as PDF" in the print dialog for a single combined file; "Download all" saves a .zip of one .txt per record. Everything runs on your device — your list never leaves it.
