\ud83d\udccc Overview\n\nThis workflow monitors an Excel 365 sheet every minute and detects new, updated, and deleted rows using a unique ID column. It compares the current dataset with the previous snapshot and identifies field-level differences.\n\nWhen changes are detected, the workflow filters rows that require approval (Status = \u201cWaiting Approval\u201d), sends structured notifications, and optionally logs every field-level change into an audit sheet (Excel or Google Sheets).\n\nThe configuration layer allows you to define the ID column, ignored fields, and audit logging behavior without modifying the comparison logic.\n\nThis template is suitable for approval tracking, operational monitoring, and lightweight compliance logging.\n\n\u2e3b\n\n## \ud83d\ude80 Features\n\n### \u23f1 Scheduled Monitoring\n- Runs automatically every 1 minute\n- Near real-time Excel monitoring\n- Prevents unnecessary execution when no changes are detected\n\n### \ud83d\udd0d Row-Level Change Detection\n\n### Detects:\n- \u2705 New rows\n- \u270f\ufe0f Updated rows\n- \u274c Deleted rows\n\nUses a unique ID field per row for accurate tracking.\n\n\u2e3b\n\n### \ud83e\udde0 Field-Level Comparison\n- Compares previous vs current values\n- Identifies exactly which fields changed\n- Outputs structured change data\n- Prevents false positives via data normalization\n\n\u2e3b\n\n## \u2699\ufe0f Environment Configuration Layer\n\nCentralized configuration node allows easy customization without modifying core logic.\n\n## Configurable options include:\n- idField\n- ignoreFields\n- monitorOnly\n- firstRunSilent\n- enableAuditLog\n\nNo hardcoded logic required.\n\n\u2e3b\n\n## \ud83d\uded1 Approval Validation Layer\n- Filters rows where Status = \"Waiting Approval\"\n- Sends notifications only for relevant approval cases\n- Prevents unnecessary alerts\n\n\u2e3b\n\n## \ud83d\udd14 Smart Notification System\n- Sends formatted change notifications\n- Includes:\n- Change Type (NEW / UPDATED / DELETED)\n- Row ID\n- Field-level old \u2192 new values\n\nFully customizable message formatting.\n\u2e3b\n## \ud83d\udcca Optional Audit Logging\n\nIf enabled in the Environment Config:\n- Converts each field-level change into structured audit rows\n- Appends logs to:\n- Excel 365 (Audit Sheet)\n- Google Sheets (External Log)\n\nAudit Log Structure\n\n| Timestamp | ChangeType | RowID | Field | OldValue | New Value |\n|-------------|--------------|--------|------|----------|------------|\n\nDesigned for compliance and tracking purposes.\n\n## \ud83d\udce6 Use Cases\n- Internal approval tracking\n- Financial data monitoring\n- Sales pipeline control\n- Procurement workflows\n- Excel-based compliance systems\n- SME automation systems\n\n## \ud83e\udde9 Requirements\n- Microsoft 365 (Excel Online \u2013 Business)\n- n8n (Cloud or Self-hosted)\n- Microsoft credentials configured in n8n\n- Telegram Bot\n- (Optional) Google Sheets credentials for audit logging\n\n## \ud83d\udd27 Configuration Guide\nAll system behavior is controlled from the Environment Config node.\n\nExample configuration structure:\n\n```\n{\n CONFIG: {\n idField: \"ID\",\n ignoreFields: [\"UpdatedAt\", \"LastModified\"],\n monitorOnly: null,\n firstRunSilent: true,\n enableAuditLog: true\n }\n}\n```\n\nYou can customize:\n- Which column acts as unique ID\n- Which fields to ignore\n- Which fields to monitor exclusively\n- Whether to enable audit logging\n- Whether first run should be silent\n\n## \ud83d\udfe2 First Run Behavior\nOn first execution:\n- The workflow initializes internal snapshot storage\n- No mass notification is sent (if firstRunSilent = true)\n\nThis prevents false \u201cNEW row\u201d alerts during setup.\n## \ud83c\udfe2 Who Is This For?\n- Operations teams\n- Finance departments\n- SMEs using Excel as core system\n- Automation consultants\n- Businesses requiring lightweight audit tracking\n\n\u2e3b\n\n## \ud83d\udca1 Why This Workflow?\n\nUnlike simple Excel polling workflows, this solution:\n- Tracks changes at field level\n- Supports approval-based filtering\n- Includes structured audit logging\n- Avoids duplicate alerts\n- Is fully configurable\n- Designed for production usage\n\nThis is not just an Excel notifier \u2014 it is a structured Change Tracking & Approval Monitoring System built on n8n." }, "typeVersion": 1 }, { "id": "6d5867c7-9ce0-493d-af68-d4b921f04c39", "name": "Notification Approval", "type": "n8n-nodes-base.telegram",
