Title: Automate event planning & budget optimization with Claude AI and Google Sheets
Workflow name: Automate event planning & budget optimization with Claude AI and Google Sheets

This enterprise-grade n8n workflow automates the entire event planning lifecycle — from client briefs to final reports — using Claude AI, real-time financial data, and smart integrations. It converts raw client data into optimized, insight-driven event plans with cost savings, risk management, and automatic reporting, all with zero manual work.

Key Features

Multi-source data fusion from Google Sheets (ClientBriefs, BudgetEstimates, ActualCosts, VendorDatabase)
AI-powered orchestration using Claude 3.5 Sonnet for event plan optimization
Automatic ROI and variance analysis with cost-saving insights
Vendor intelligence — ranks suppliers by cost, rating, and reliability
Risk engine computes event risk (probability × impact)
Auto-approval logic for safe, high-ROI events
Multi-channel delivery: Slack + Email + Google Sheets
Audit-ready: Full JSON plan + execution logs
Scalable triggers: Webhook or daily schedule

Tag stale ClickUp tasks and escalate overdue items with assignee comments

## Quick overview This workflow runs daily on a schedule and checks ClickUp tasks in one or more lists for inactivity based on the task’s date_updated field, automatically applying “stale” tags and escalating long-idle tasks by tagging them and posting an assignee comment. ## How it works 1. Runs every day at the configured hour using the schedule trigger. 2. Loads monitoring settings (statuses, tags, stale thresholds, and tag names) and fetches matching tasks from the selected ClickUp list(s), then merges and deduplicates them. 3. Skips tasks that already have the second-level stale tag (for example, stale:14). 4. For tasks without the first-level stale tag, checks the last updated timestamp and adds either the first-level stale tag (for example, stale:7) or the second-level stale tag if they already exceed the higher threshold. 5. For tasks that already have the first-level stale tag, checks whether enough time has passed since that tag was applied and, if so, removes the first-level tag and adds the second-level stale tag. 6. When a task is escalated to the second-level stale tag, posts a warning comment on the ClickUp task and assigns the comment to the task assignee (or the creator if no assignee exists). ## Setup 1. Add a ClickUp API credential (OAuth or API token) and select it on all ClickUp nodes. 2. In the ClickUp task search node(s), choose the list(s) you want to monitor and enable/configure the second list node if you want to pull tasks from multiple lists. 3. Update the monitoring settings (monitoredStatuses, monitoredTags, daysUntilFirstStaleTag, daysUntilSecondStaleTag, and the stale tag names) to match your ClickUp workspace conventions. 4. Adjust the schedule trigger time and, if needed, set the workflow timezone in n8n settings so the run time matches your local time. ## Requirements - A ClickUp account with API access - ClickUp credential configured in n8n - At least one ClickUp list to monitor ## Customization - Change thresholds — Edit `daysUntilFirstStaleTag` and `daysUntilSecondStaleTag` in `SetContext` to any number of days - Change tag names — Update `firstStaleTagName` / `secondStaleTagName` to match your ClickUp tag naming convention - Monitor different statuses — Edit `monitoredStatuses` and `monitoredTags` in `SetContext` (e.g. add `review`, `blocked`) - Add more lists — Duplicate `GetTaskFromList1`, update the List ID, enable the node, and connect its output to a new input port on `AppendListTasks` - Change schedule — Open `TriggerRegularly` and switch from daily to weekdays-only or any custom cron interval - Disable subtasks — Open each `GetTaskFromList` node and set `subtasks` to `false` in the Filters section

Summarize daily Slack standups with OpenAI, Notion, and Google Sheets

## Quick overview This workflow runs every weekday, pulls standup messages from a Slack channel, uses OpenAI to generate a structured daily digest, saves the digest to a Notion database, posts a summary back to Slack, and appends an audit entry to Google Sheets. ## How it works 1. Runs every weekday morning on a cron schedule. 2. Fetches the day’s recent messages from a specified Slack standup channel and filters out bot, subtype, and join/leave system messages. 3. Checks whether any standup messages remain and posts a Slack notice if none are found. 4. Formats the remaining Slack updates into a single structured prompt with date, team name, and message count. 5. Sends the formatted standup text to OpenAI (gpt-4.1-mini) to generate a JSON digest with summary, highlights, blockers, per-user updates, and mood. 6. Parses and enriches the AI output with metadata, creates a new page in a Notion database, posts the digest to a Slack summary channel, and appends a run record to a Google Sheets “Audit Log” sheet. ## Setup 1. Add a Slack OAuth2 credential and set the standup channel ID (history source) and the summary channel ID (digest destination). 2. Add an OpenAI credential and confirm the model selection (gpt-4.1-mini) is available in your account. 3. Add a Notion credential, create/select a target database, and replace `YOUR_NOTION_DATABASE_ID` (and ensure the database has the referenced properties: Date, Team, Message Count, Mood). 4. Add a Google Sheets Service Account credential, share the target spreadsheet with the service account email, and replace `YOUR_SHEET_ID` and the sheet name (“Audit Log”) if different. 5. Adjust the schedule cron expression (`0 9 * * 1-5`) to match your team’s standup timing and timezone expectations.

Sync check due dates from Google Sheets to Google Calendar with Telegram alerts

## Quick overview This workflow watches a Google Sheets check inventory list and creates or updates matching all-day events in Google Calendar, then posts a creation or update notice to a Telegram group. ## How it works 1. Polls Google Sheets every hour for any updates in the “Check Inventory” sheet. 2. Checks whether the updated row already contains a Google Calendar Event ID. 3. If the Event ID is empty, searches Google Calendar for an existing event whose text matches the check number and backfills the found Event ID to Google Sheets. 4. If no matching calendar event exists, creates an all-day Google Calendar event using the check date and details from the Google Sheets row, then writes the new Event ID back to the sheet. 5. If an Event ID exists, fetches the corresponding Google Calendar event and compares its date, summary, and description to the latest Google Sheets values. 6. When differences are detected, updates the Google Calendar event to match the sheet and sends a Telegram message summarizing the created or updated events. ## Setup 1. Connect credentials for Google Sheets (including Google Sheets Trigger), Google Calendar OAuth2, and a Telegram Bot API account. 2. Replace `YOUR_CHECK_INVENTORY_SHEET_ID` in all Google Sheets nodes and ensure the “Check Inventory” sheet contains the required columns (including “Check Number” and “Event ID”). 3. Set the target Google Calendar ID (for example `[email protected]` or a shared calendar ID) in the Google Calendar nodes. 4. Replace `YOUR_TELEGRAM_GROUP_CHAT_ID` in the Telegram nodes and edit the message text to use the correct @mentions for your team.
