N8N · Invoice CSV
An invoice in n8n, fields for human review
This free workflow receives an invoice through an n8n form and calls Invoice CSV. It returns eight fields, warnings and a “human review required” status. It stops before any automatic export or accounting entry.
Set up and review
- Create an Invoice CSV account and confirm the emailed access link. The free quota is enough to try it.
- Create a key in your workspace. In n8n, create a Header Auth credential: Name = Authorization; Value = Bearer followed by a space and your key.
- Import the JSON file, attach this credential to “Extract invoice fields”, then open the form test URL.
- Upload a PDF, PNG or JPEG. Open the last node output and compare the fields with the original.
- To review and export CSV in the browser: download the node JSON response, select the original in your workspace, then “Load JSON result”. Correct and confirm before exporting.
Requirements and limits
The workflow requires an n8n instance and a free or Pro Repondea account. It uses native nodes and your secured credential, with no model API key. n8n may retain files and results in its execution history: configure retention in your instance. CSV export follows your review and is never sent automatically to accounting software.
