Aggregate Marketing Spend Data with Custom Pivots & VLOOKUPs in Google Sheets

This workflow transforms raw marketing data from Google Sheets into a pivot-like summary table. It merges lookup data, groups spend by name, and appends the results into a clean reporting tab — all automatically, without needing to manually build pivot tables in Sheets.

🧑‍💻 Who’s it for Marketing analysts who track channel spend across campaigns
Small businesses that rely on Google Sheets for reporting
Teams that need automated daily rollups without rebuilding pivot tables manually

⚙️ How it works Get Marketing Data (Google Sheets) – Pulls raw spend data.
Vlookup Data (Google Sheets) – Brings in reference/lookup fields (e.g., channel labels).
Merge Tables – Joins marketing data and lookup data on the Channel column.
Summarize – Groups data by Name and sums up Spend ($).
Clear Sheet – Wipes the reporting tab to avoid duplicates.
Append to Pivot Sheet – Writes the aggregated results into the "render pivot" sheet.

The result: a pivot-style summary table inside Google Sheets, automatically refreshed by n8n.
