How Does n8n Handle Files and Binary Data?
n8n stores files as binary data in a separate binary property on each item, kept apart from the item's JSON. This lets workflows download, read, transform, and upload files like CSVs, PDFs, images, and spreadsheets while still passing structured JSON alongside them.
How to Work With Files in n8n
Use Read/Write Files from Disk to load or save local files, and the HTTP Request node to download or upload them over the web. Convert between formats with Extract From File, which reads a CSV, PDF, or spreadsheet into JSON, and Convert To File, which builds a file from JSON to send onward. Always reference a file by its binary property name so the next node can find it.
