  title: Ramp Transactions to Google Sheet and Slack
  summary: Export Ramp card transactions to a Google Sheet, then post a spend summary to Slack.
  description: >-
    A spend-visibility workflow that pulls recent card transactions from Ramp,
    appends them as rows to a Google Sheet for finance review, and posts a
    summary message to a Slack channel so the team sees new spend activity.
    Demonstrates fanning a corporate-card data source out to a spreadsheet and a
    chat channel in one pass.
