Why connect Google Sheets to Codex?

Codex runs in your terminal, its IDE extension and scripts, so what it finds once can be rerun with codex exec instead of redone by hand. Connected through Lemonado, it reads your Google Sheets media plans, targets, offline sales and UTMs, so it can join offline sales with ad clicks with today's numbers.

  • All your Google Sheets data

    Any tab you connect, as a table, ready to ask about.

  • Always today's numbers

    Targets and forecasts, synced from Google Sheets automatically, so answers use today's numbers.

  • Connect all your tools

    Questions like "Is the forecast holding?" use Google Sheets and GA4, Google Ads at once.

    Run codex mcp list, or /mcp inside Codex, to see the server and its tools. Try "Pull last week's Google Sheets numbers, save them to data/google-sheets-weekly.csv and give me the codex exec command to refresh it." Or ask: "Are the targets up to date?" or "What's in the media plan?"

What can Codex do with Google Sheets?

Codex reads your Google Sheets data from your terminal and turns one-off questions into commands you can rerun with codex exec.

Pull last week's Google Sheets numbers, save them to data/google-sheets-weekly.csv and give me the codex exec command to refresh it.

Saved data/google-sheets-weekly.csv. Run the same prompt with codex exec in a scheduled job and the file refreshes with each week's numbers.
