Free CSV Invoice Template — Export & Open in Excel or Google Sheets
A CSV (comma-separated values) invoice is the most portable format there is: it opens in every spreadsheet app and imports cleanly into accounting tools. Billify generates a clean, RFC-4180 CSV straight from your browser — with cells properly quoted and formula-injection characters neutralized so Excel and Sheets open it safely. No signup, no account, and no .xlsx lock-in: your data is yours to move wherever you want.

CSV invoice FAQ
Is the CSV invoice template really free?
Yes. The free tier lets you create and export up to 3 invoices a month with no signup and no watermark. The CSV export is included on the free tier — you don’t need Pro to download a CSV.
Will the CSV open correctly in Excel and Google Sheets?
Yes. Billify follows RFC 4180 (commas, quotes, and newlines are escaped correctly) and prefixes cells that start with =, +, -, or @ with a single quote, so Excel and Sheets treat them as text rather than formulas — a standard protection against CSV formula injection.
Is my invoice data stored on a server?
No. Billify is browser-first: your invoice lives in your browser’s local storage and the CSV is generated on your device. There is no server-side database of invoices, so nothing to leak.
