Step 1: Start with Headers Create a clean Excel sheet. Use row 1 for headers like: First Name | Last Name | Company | Address | City | State | ZIP Step 2: Fill in Your Data Add one contact per row—no blank rows, no merged cells. Each column holds only one type of data. Step 3: Save as .CSV Go to File → Save As Choose CSV (Comma delimited) (.csv) If prompted about features not supported, click Yes Step 4: Import into Mail Merge Use the CSV in Word, Mailchimp, Constant Contact, or your label software. Why CSV Works Best It's plain text with commas—no hidden styling or formatting. Universally accepted by mail merge tools. Keeps your data clean and ready to merge.
