You do not need Python to pull options chains excel. The Eulerpool add-in for Excel and Google Sheets maps this endpoint to a formula. Paste, refresh, done.
Load options chains into a spreadsheet with =EP.OPTIONS("SPY") — no CSV export step.
What the data contains
- Full US options chain: strikes, expirations, bid/ask, open interest, volume
- Greeks (delta, gamma, theta, vega, rho) computed at the quote
- Intraday implied-vol surface snapshots for vol-trading systems
The endpoint
Primary path /v1/options/{ticker}/chain. Authenticate with a Bearer token. Errors are JSON with a stable code field so retries are mechanical.
=EP.OPTIONS("SPY")Authentication
Send Authorization: Bearer YOUR_KEY. Keys are created at register in under a minute. Official SDKs take the key in the constructor; Excel stores it in the add-in settings. There is no key-in-query-string mode — do not paste tokens into public notebooks.
Primary route for this article: /v1/options/{ticker}/chain. Docs: /financial-data-api/options-futures-data.
Coverage and freshness
Eulerpool maps 100,000+ securities across 90+ exchanges. options chains excel rides that same reference layer — identifiers resolve through ticker, name, ISIN, or CUSIP via search, so a European name is not a dead end. History depth depends on the source: prices and macro go back 100+ years, 1-minute bars to 2010, 13F to 2013.
Paid plans can stream quotes over WebSocket; the free plan uses REST with a 15-minute delay on real-time equity fields. Fundamentals, ownership, and calendars are identical on every plan. Rate-limit headers ship on every response. Batch routes (up to 100 symbols) count as one request.
Spreadsheet specifics
Install from Microsoft AppSource or Google Workspace Marketplace. Formula family is EP.*. Auto-refresh keeps a dashboard live without a daily paste. More: Excel integration.
Fit versus other sources
Most teams land here after fighting Yahoo Finance scrapers, Alpha Vantage’s 25-request/day ceiling, or a Polygon bill that ignored fundamentals. Eulerpool is a licensed options chains excel with statements, estimates, filings, and macro on the same key — and a terms of service you can actually show legal.
Deep comparisons live here: vs Alpha Vantage, vs Polygon, Yahoo Finance alternative, best stock market APIs in 2026.
Who should call this
- Quant research — pandas/R dataframes, point-in-time fields, 20+ years of history where the source publishes it.
- Fintech apps — watchlists, screeners, and portfolio views without relicensing Bloomberg for every customer.
- AI agents — typed JSON and a native MCP server so models stop inventing numbers for Options Chains in Excel and Google Sheets.
- Spreadsheets — the Excel and Google Sheets add-in covers the same endpoints as REST.
Options Chains in Excel and Google Sheets is one slice of the Eulerpool Financial Data API. Adjacent routes — quotes, statements, ownership, macro — use the same key, so a prototype that starts here does not hit a wall at the second dataset.
Get started
Create a free key at eulerpool.com/developers/register — no credit card, 100,000 requests/month. Then read the options chains excel docs or the Excel guide and ship.
Every day’s drop is listed on the Financial Data API changelog. Same data powers the Eulerpool terminal 500,000+ investors already use — the API is that database with a key in front of it.
