Claude splits it into date, amount, category and memo, code checks the result against your note, and the row lands in Google Sheets. A reply in the room says what was recorded.\n\n### How it works\n1. Every 5 minutes it reads the latest 100 messages of the rooms you list (Chatwork has no n8n node, so this uses the API). Every message is cleaned and logged in the `log` tab.\n2. A message that contains the keyword (default #記録) is read by Claude.\n3. **Code checks every record:** the amount must be written in the note, the date words are turned into a date by code (昨日, 10/3, 先週金曜), the category must be in your list. Anything doubtful is saved as 要確認 with the reason, never dropped.\n4. Rows go to the `records` tab. One reply per note is posted in Chatwork.\n\n### Setup\n1. Create a blank Google Sheet. Paste its ID in **Spreadsheet ID**, run the **Run once** branch (it adds the `log` and `records` tabs and the header rows), and select the sheet in the three Google Sheets nodes.\n2. Credentials: Header Auth for Chatwork (Name `x-chatworktoken`, Value = your API token only, no \"Bearer\"), Google Sheets OAuth2, Anthropic.\n3. Put your room IDs in **Config** (the number after `#!rid` in the room URL). Edit the category list.\n4. Publish.\n\n### Customization\nChange the keyword, the categories and their examples, or turn off replies in **Config**.", "height": 860, "width": 780, "color": 1 }, "type": "n8n-nodes-base.stickyNote", "typeVersion": 1, "position": [ -130, -1384 ], "id": "sticky-1-f3895132", "name": "Overview" } ], "connections": { "Every 5 minutes": { "main": [ [ { "node": "Config", "type": "main", "index": 0 } ] ] }, "Run now": { "main": [ [ { "node": "Config", "type": "main", "index": 0 } ] ] }, "Config": { "main": [ [ { "node": "Get room names", "type": "main", "index": 0 } ] ] }, "Get room names": { "main": [ [ { "node": "Split rooms", "type": "main", "index": 0 } ] ] }, "Split rooms": { "main": [ [ { "node": "Get messages", "type": "main", "index": 0 } ] ] }, "Get messages": { "main": [ [ { "node": "Add room", "type": "main", "index": 0 } ] ] }, "Add room": { "main": [ [ { "node": "Clean messages", "type": "main", "index": 0 } ] ] }, "Clean messages": { "main": [ [ { "node": "Keep new messages only", "type": "main", "index": 0 }, { "node": "Is it an accounting note?", "type": "main", "index": 0 } ] ] }, "Keep new messages only": { "main": [ [ { "node": "Add to log sheet", "type": "main", "index": 0 } ] ] }, "Is it an accounting note?": { "main": [ [ { "node": "Read recorded notes", "type": "main", "index": 0 } ] ] }, "Read recorded notes": { "main": [ [ { "node": "Skip notes already recorded", "type": "main", "index": 0 } ] ] }, "Skip notes already recorded": { "main": [ [ { "node": "AI: Extract records", "type": "main", "index": 0 } ] ] }, "AI: Extract records": { "main": [ [ { "node": "Check records", "type": "main", "index": 0 } ] ] }, "Check records": { "main": [ [ { "node": "Add to records sheet", "type": "main", "index": 0 } ] ] }, "Add to records sheet": { "main": [ [ { "node": "Build Chatwork reply", "type": "main", "index": 0 } ] ] }, "Build Chatwork reply": { "main": [ [ { "node": "Reply in Chatwork", "type": "main", "index": 0 } ] ] }, "Run once: set up the sheet": { "main": [ [ { "node": "Spreadsheet ID", "type": "main", "index": 0 } ] ] }, "Add the log and records tabs": { "main": [ [ { "node": "Write the header rows", "type": "main", "index": 0 } ] ] }, "Spreadsheet ID": { "main": [ [ { "node": "Add the log and records tabs", "type": "main", "index": 0 } ] ] } }, "settings": { "executionOrder": "v1" }, "pinData": {} }
