Track OpenAI API Usage & Costs Automatically with Google Sheets

This workflow helps teams monitor OpenAI expenses by automatically collecting API usage and cost data every few days (default: 3 days) via the OpenAI Admin API. It fetches comprehensive metrics like token usage, model breakdowns, and line-item costs for every project and API key, then enriches the data with project and key names for clarity before appending it to a Google Sheets template.

Key benefits include effortless spend tracking, historical audit trails, and actionable insights without manual reporting. Finance and ops teams gain visibility into AI budgets, data analysts get granular breakdowns, and admins simplify organization-wide monitoring—saving hours of manual data pulls and spreadsheet management.

Ideal for finance/ops tracking AI spend, data teams needing project-level details, technical leads managing usage, or anyone requiring OpenAI activity records. Setup is straightforward: add OpenAI Admin credentials (separate from model API keys), Google Sheets auth, and copy the provided template. Adjustable schedule ensures flexibility for any cadence.
