Mail merge letters
Upload a CSV, write one letter with {{column}} placeholders, and get a personalized letter for every row — preview them, then print or save them all as PDF. Everything runs in your browser; nothing is uploaded.
CSV file
Drop your CSV here, or click to choose
A header row plus one row per recipient

Letter template
Upload a CSV first to see your placeholders and preview.
Your CSV is read and merged entirely in your browser. Nothing is uploaded.
How it works
STEP 1
Upload your CSV
Drop a CSV with a header row. Each column name becomes a placeholder you can use, like {{name}} or {{city}}.
STEP 2
Write your template
Type one letter and insert {{column}} placeholders. The preview fills in real data for each row as you go.
STEP 3
Print or export
Print or save every letter as a single PDF (one page each), or download all letters as a combined .txt — nothing is uploaded.
