Hi n8n Community! 
Here is a ready-to-use n8n workflow designed to **automatically extract and structure accounting invoices, receipts, and quotes into clean JSON**.
### 
What this workflow does:
1. Receives incoming invoice data (from Gmail or Webhooks).
2. Sends it to **DocToJSON API** (`https://91.98.169.170.sslip.io/v1/parse/text\`).
3. Returns deterministic JSON containing supplier name, dates, line items, and total amounts.
4. Outputs the structured data directly into Google Sheets or your CRM.
### 
Setup Instructions:
1. Import the workflow JSON file attached below into your n8n instance.
2. Get an API key from [DocToJSON API](https://91.98.169.170.sslip.io/).
3. Set your `X-API-Key` header in the HTTP Request node.
Feel free to test it and share your feedback!
