Envelope printing from CSV

Why CSV to envelopes is so common

CSV is the universal export: CRMs, databases, event tools, and spreadsheets all output CSV. When you need to mail that list, you need envelope printing from CSV—a way to go from rows of data to physical (or print-ready) envelopes. You can do it in Word, or use List Processor and skip the column mapping.

How to print envelopes from a CSV in Word

In Word you use Mailings → Start Mail Merge → Envelopes (or Letters), then:

1. Select Recipients → Use an Existing List and browse to your CSV. Word may prompt you to choose a delimiter (comma, semicolon, tab) and which row contains headers.
2. Map columns to merge fields. Word expects fields like «FirstName», «AddressLine1», «City», «State», «PostalCode». Your CSV might have “First Name”, “Address 1”, “Zip”—you have to match them in the Mail Merge Recipients dialog or the merge fails or puts the wrong data in the wrong place.
3. Insert merge fields into the envelope or letter layout in the correct order.
4. Preview and fix. If the CSV has extra columns, blank rows, or different column order in another export, you may get wrong names on wrong envelopes until you fix the mapping or the file.
5. Finish & Merge to print or save as PDF.

One wrong column mapping and you get the wrong name on the wrong envelope. Re-export from a different tool and you may have to re-map.

List Processor handles CSV without column mapping

Upload your CSV file or paste CSV data at List-Processor.com. List Processor parses the content and detects name and address fields—you don’t tell it which column is “address” or “city.” Choose your envelope size (#10, 6×9, 9×12, or custom), add a return address if you like, and generate. You get a single PDF, one envelope per page, ready for your printer or mail house. Same workflow whether your CSV came from Excel, a CRM, or an export from another tool.

No column mapping required

Different CSVs use different column orders and headers. List Processor is built to handle that. It looks at the data and standardizes addresses; you’re not mapping “Column C” to “Address Line 1.” If your CSV has extra columns (phone, email, etc.), List Processor ignores them for the envelope output. You just need something that looks like names and addresses.
