When the batch finishes, the form shows a summary marking each file \u2705 or \u274c, so you instantly see which invoices need a second look.\n\n**Who it's for:** finance and ops teams who receive invoices in bulk and want structured data without manual entry.\n\n## \u2699\ufe0f How it works\n1. Upload one or many invoices through the form.\n2. Each file is split into its own item.\n3. The loop sends one file at a time to the Extractor (it returns one result per request).\n4. The filename is reattached and the core fields are checked.\n5. A row is appended to the Sheet for every invoice.\n6. A summary lists each file with \u2705 or \u274c on the completion screen.\n\n## \ud83d\udee0\ufe0f Set up steps\nTakes about 10 minutes.\n\n**1. Install the Extractor node**\nn8n Cloud: search \"easybits\" in the nodes panel (verified node) and add it.\nSelf-hosted: Settings \u2192 Community Nodes \u2192 Install \u2192 `@easybits/n8n-nodes-extractor`.\n\n**2. Create your pipeline**\nSign up at extractor.easybits.tech, create a pipeline, and add your invoice fields. Fastest way: upload one example invoice and use auto-mapping to detect and map every field, then tweak the field descriptions. Free tier covers 50 extractions per month. Copy the API key.\n\n**3. Connect it in n8n**\nOn the Extract node, add your easybits credential with the API key, and read the binary property named `data`.\n\n**4. Point the Sheet node at your own sheet**\nSelect your spreadsheet and tab, and set value input to RAW so amounts and dates store exactly as extracted.\n\nDocs: extractor.easybits.tech/documentation/integration" }, "typeVersion": 1 }, { "id": "b1a11111-0000-4000-8000-000000000001", "name": "Section: Upload & Split", "type": "n8n-nodes-base.stickyNote", "position": [ 80, -240 ], "parameters": { "color": 7, "width": 520, "height": 480, "content": "## 1.
