Snapshot Site This workflow corresponds to n8n.io template #17668 — we link there as the canonical source.
This workflow follows the Google Sheets → Informationextractor recipe pattern — see all workflows that pair these two integrations.

"content": "## Events Extractor \u2192 Google Sheets\n\n### How it works\n\nThis workflow runs daily and reads a list of event-listing page URLs from a Google Sheet. For each URL, it captures the fully-rendered page HTML with Snapshot Site, cleans it, and passes it to an AI Information Extractor that pulls out structured event fields. Extracted events are appended to a results sheet (deduplicated by registration URL); comparison failures are logged to an errors sheet instead of stopping the run.\n\n### Setup steps\n\n- Install the `n8n-nodes-snapshot-site` community node (Settings \u2192 Community nodes \u2192 Install \u2192 `n8n-nodes-snapshot-site`) \u2014 verified by n8n.\n- Add a Snapshot Site credential, a Google Sheets credential, and an AI chat model credential (e.g. OpenAI) for the Information Extractor.\n- Create a source sheet with a `url` column (one event page per row) and a results sheet with columns matching the extracted fields (see the workflow README for the full list).\n- Paste this exact header row into row 1 of the **Events** tab (tab-separated, one column per cell): `eventName\torganizer\tcategory\tstartDate\tendDate\ttime\tvenue\taddress\tcity\tcountry\tonlineOrOffline\tticketPrice\tregistrationUrl\tdescription`\n- Paste this header row into row 1 of the **Extraction Errors** tab: `url\tmessage\toccurredAt`\n- After importing, open the two Google Sheets write nodes (Log Extraction Error, Save Events) and switch Mapping Column Mode from \"Map Each Column Manually\" to \"Map Automatically\" \u2014 it always imports blank regardless of the JSON, but since the sheet headers above already match the incoming field names, this needs no manual typing.\n- Point the two Google Sheets nodes at your spreadsheet and adjust the schedule.\n\n### Customization\n\nAdd more source columns (e.g. a `region` tag), swap the AI model, or point the same Clean HTML \u2192 Extractor pattern at a different page type \u2014 this is the base pattern for every extraction workflow in this collection."
