RETURN ONLY THE SANITIZED JSON OBJECT.\n - No explanations, no markdown, no code fences, no text outside the JSON.\n - Output must be valid JSON.\n\n2. REMOVE the following everywhere in the workflow:\n - Any key named \"credentials\"\n - Any key named \"webhookId\"\n - Root-level: \"meta\", \"versionId\", \"id\"\n\n3. STICKY NOTES (type: \"n8n-nodes-base.stickyNote\"):\n - Do not modify them in any way.\n - Do NOT sanitize emails, URLs, or text inside sticky notes.\n - Preserve their content, color, size, position, and metadata.\n\n4. DO NOT MODIFY:\n - Node id, name, type, typeVersion\n - Node positions\n - Connections\n - Any n8n expression syntax (for example, expressions that begin with \"=\" and use n8n-style placeholders).\n\n5. REPLACE secret-like values with placeholders:\n - clientId \u2192 \"YOUR_CLIENT_ID_HERE\"\n - clientSecret \u2192 \"YOUR_CLIENT_SECRET_HERE\"\n - API keys / tokens \u2192 \"YOUR_API_KEY_HERE\", \"YOUR_BEARER_TOKEN\", or \"REDACTED_TOKEN\"\n - Email addresses \u2192 \"YOUR_EMAIL@EXAMPLE.COM\"\n - Public document URLs \u2192 \"REPLACE_WITH_YOUR_URL\"\n\n6. SPECIAL RULES:\n - Google Translate (service account): remove credentials; keep authentication field; no other changes.\n - ConvertAPI URLs: replace Secret=... with Secret=YOUR_CONVERTAPI_SECRET or append if missing.\n - Gmail OAuth2 nodes: remove Gmail credentials object.\n - JavaScript nodes: only replace literal strings containing secrets; do not change code structure.\n\n7. The final output must be:\n - A single valid JSON object\n - Sanitized according to all rules\n - Directly importable into n8n.\n\nIf the workflow is very large, you may truncate fields like systemMessage or long descriptions only if needed to stay within the model\u2019s context limit, but keep structure and logic intact.\n"
