This n8n workflow automates the process of creating personalized invoices from a Google Sheets spreadsheet using Google Docs. When triggered manually, the workflow retrieves invoice data from Google Sheets, loads a pre-designed invoice template from Google Docs, and then generates customized invoices for each row of data. The process includes key steps such as loading data, duplicating the template, merging data with placeholders, and replacing placeholders with actual invoice details, resulting in ready-to-use invoice documents stored in Google Drive. This workflow is ideal for small businesses or freelance professionals seeking a streamlined, on-demand method for producing consistent, branded invoices without manual editing.
