Quick overview This workflow collects an invoice PDF via an n8n Form, extracts text from the PDF, uses OpenAI to convert it into structured invoice JSON, logs invoice headers and line items to Google Sheets, validates totals, and emails a formatted extraction report via Gmail. How it works Receives an invoice submission through an n8n Form that includes the uploader’s name, email address, currency, notes, and a PDF file. Extracts text content from the uploaded PDF. Sends the extracted text to OpenAI (Chat Completions) to return invoice fields and all line items as a strict JSON object. Parses and validates the returned JSON, enriching it with the form metadata and stopping the run if key fields (like invoice number or line items) are missing. Appends a single invoice “header” row to the Invoices tab in Google Sheets. Splits the extracted line items, adds per-line metadata and a unique key, and appends each line item as a row to the Line Items tab in Google Sheets. Aggregates all line items, verifies that their summed totals match the invoice total within a tolerance, builds an HTML report, and emails it to the submitter via Gmail.
